Illustration of the Black Death from the Toggenburg Bible (1411)

The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350. Although there were several competing theories as to the etiology of the Black Death, it has been conclusively proven via analysis of ancient DNA from plague victims in northern and southern Europe that the pathogen responsible is the Yersinia pestis bacterium.^[1] Thought to have started in China or central Asia,^[2] it travelled along the Silk Road and reached the Crimea by 1346.

From there it was probably carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. It spread throughout the Mediterranean and Europe. The Black Death is estimated to have killed 30–60 percent of Europe's population,^[3] reducing world population from an estimated 450 million to between 350 and 375 million in the 14th century. The aftermath of the plague created a series of religious, social and economic upheavals, which had profound effects on the course of European history. It took 150 years for Europe's population to recover. The plaugue occasionally reoccurred in Europe until 19th century.

Overview[link]

Inspired by the Black Death, The Dance of Death, an allegory on the universality of death, is a common painting motif in the late medieval period.

There have been three major outbreaks of plague. The Plague of Justinian in the 6th and 7th centuries is the first known attack on record, and marks the first firmly recorded pattern of bubonic plague. From historical descriptions, as much as 40 percent of the population of Constantinople died from the plague. Modern estimates suggest half of Europe's population was wiped out before the plague disappeared in the 700s.^[4] After 750, major epidemic diseases did not appear again in Europe until the Black Death of the 14th century.^[5] The Third Pandemic hit China in the 1890s and devastated India but was confined to limited outbreaks in the west.^[6]

The Black Death originated in or near China and spread by way of the Silk Road or by ship.^[6] It may have reduced world population from an estimated 450 million to between 350 and 375 million in 1400.^[7]

The plague is thought to have returned at intervals with varying virulence and mortality until the 18th century.^[8] On its return in 1603, for example, the plague killed 38,000 Londoners.^[9] Other notable 17th-century outbreaks were the Italian Plague (1629–1631), the Great Plague of Seville (1647–1652), the Great Plague of London (1665–1666),^[10] and the Great Plague of Vienna (1679). There is some controversy over the identity of the disease, but in its virulent form, after the Great Plague of Marseille in 1720–1722,^[11] the Great Plague of 1738 (which hit Eastern Europe), and the Russian plague of 1770-1772, it seems to have gradually disappeared from Europe. By the early 19th century, the threat of plague had diminished, but it was quickly replaced by a new disease. The Asiatic cholera was the first of several cholera pandemics to sweep through Asia and Europe during the 19th and 20th centuries.^[12]

The 14th century eruption of the Black Death had a drastic effect on Europe's population, irrevocably changing the social structure. It was, arguably, a serious blow to the Catholic Church, and resulted in widespread persecution of minorities such as Jews, foreigners, beggars, and lepers. The uncertainty of daily survival has been seen as creating a general mood of morbidity, influencing people to "live for the moment", as illustrated by Giovanni Boccaccio in The Decameron (1353).^[13]

Naming[link]

Medieval people called the catastrophe of the 14th century either the "Great Pestilence"' or the "Great Plague".^[14] Writers contemporary to the plague referred to the event as the "Great Mortality". Swedish and Danish chronicles of the 16th century described the events as "black" for the first time, not to describe the late-stage sign of the disease, in which the sufferer's skin would blacken due to subepidermal hemorrhages and the extremities would darken with gangrene, but more likely to refer to black in the sense of glum or dreadful and to denote the terror and gloom of the events.^[15] The German physician and medical writer Justus Hecker suggested that a mistranslation of the Latin atra mors (terrible, or black, death) had occurred in Scandinavia when he described the catastrophe in 1832^[14] in his publication "Der schwarze Tod im vierzehnten Jahrhundert". The work was translated into English the following year, and with the cholera epidemic happening at that time, "The Black Death in the 14th century" gained widespread attention and the terms Schwarzer Tod and Black Death became more widely used in the German and English speaking worlds, respectively.

Migration[link]

Populations in crisis[link]

Spread of the black death in Europe (1346–53)

In Europe, the Medieval Warm Period ended some time towards the end of the 13th century, bringing the "Little Ice Age"^[16] and harsher winters with reduced harvests. In northern Europe, new technological innovations such as the heavy plough and the three-field system were not as effective in clearing new fields for harvest as they were in the Mediterranean because the north had poor clay soil,^[14] and the potato, otherwise ideal for Northern Europe, was an American crop unknown in Europe at the time. Food shortages and rapidly inflating prices were a fact of life for as much as a century before the plague. Wheat, oats, hay and consequently livestock were all in short supply. Their scarcity resulted in malnutrition, which increases susceptibility to infections due to weakened immunity. Consistently high fertility rates, at five or more children per woman throughout Europe, resulted in high population growth rates and contributed to food shortages. In the autumn of 1314, heavy rains began to fall, followed by several years of cold and wet winters.^[14] The already weak harvests of the north suffered and the seven-year famine ensued. In the years 1315 to 1317 a catastrophic famine, known as the Great Famine, struck much of northwest Europe. It was arguably the worst in European history, reducing the population by perhaps more than 10 percent.^[14]

Infection and migration[link]

The plague disease, generally thought to be caused by Yersinia pestis, is enzootic (commonly present) in populations of fleas carried by ground rodents, including marmots, in various areas including Central Asia, Kurdistan, Western Asia, Northern India and Uganda.^[17] Nestorian graves dating to 1338–9 near Lake Issyk Kul in Kyrgizstan have inscriptions referring to plague and are thought by many epidemiologists to mark the outbreak of the epidemic, from which they could easily have spread to China and India.^[18] In October 2010, medical geneticists confirmed that the plague originated in Yunnan, province in southwest China.^[6] In China, the 13th century Mongol conquest caused a decline in farming and trading. However, economic recovery had been observed in the beginning of the 14th century. In the 1330s a high frequency of natural disasters and plagues led to widespread famine starting in 1331, with a deadly plague arriving soon after.^[19] The 14th-century plague killed an estimated 25 million Chinese and other Asians during the 15 years before it entered Constantinople in 1347.^[20] However, according to George Sussman, the first obvious medical description of plague in China dates to 1644.^[21]

The disease may have travelled along the Silk Road with Mongol armies and traders or it could have come via ship.^[22] By the end of 1346 reports of plague had reached the seaports of Europe: "India was depopulated, Tartary, Mesopotamia, Syria, Armenia were covered with dead bodies".^[23]

Plague was reportedly first introduced to Europe at the trading city of Caffa in the Crimea in 1347. After a protracted siege, during which the Mongol army under Jani Beg was suffering the disease, they catapulted the infected corpses over the city walls to infect the inhabitants. The Genoese traders fled, taking the plague by ship into Sicily and the south of Europe, whence it spread north.^[24] Whether or not this hypothesis is accurate, it is clear that several existing conditions such as war, famine, and weather contributed to the severity of the Black Death.

European outbreak[link]

There appear to have been several introductions into Europe. It reached Sicily in October 1347 carried by twelve Genoese galleys,^[25] where it rapidly spread all over the island. Galleys from Caffa reached Genoa and Venice in January 1348 but it was the outbreak in Pisa a few weeks later that was the entry point to northern Italy. Towards the end of January one of the galleys expelled from Italy arrived in Marseille.^[26]

From Italy the disease spread northwest across Europe, striking France, Spain, Portugal and England by June 1348, then turned and spread east through Germany and Scandinavia from 1348 to 1350. It was introduced in Norway in 1349 when a ship landed at Askøy, then spread to Bjørgvin (modern Bergen) but never reached Iceland.^[27] Finally it spread to north-western Russia in 1351. The plague spared some parts of Europe, including the Kingdom of Poland and isolated parts of Belgium and the Netherlands.^{[citation needed]}

Middle Eastern outbreak[link]

The plague struck various countries in the Middle East during the pandemic, leading to serious depopulation and permanent change in both economic and social structures. As it spread to western Europe, the disease also entered the region from southern Russia. By autumn 1347, the plague reached Alexandria in Egypt, probably through the port's trade with Constantinople, and ports on the Black Sea. During 1347, the disease travelled eastward to Gaza, and north along the eastern coast to cities in Lebanon, Syria and Palestine, including Ashkelon, Acre, Jerusalem, Sidon, Damascus, Homs, and Aleppo. In 1348–49, the disease reached Antioch. The city's residents fled to the north, most of them dying during the journey, but the infection had been spread to the people of Asia Minor.

Mecca became infected in 1349. During the same year, records show the city of Mawsil (Mosul) suffered a massive epidemic, and the city of Baghdad experienced a second round of the disease. In 1351, Yemen experienced an outbreak of the plague. This coincided with the return of King Mujahid of Yemen from imprisonment in Cairo. His party may have brought the disease with them from Egypt.

Symptoms[link]

A hand showing acral gangrene of the digits due to plague, the black appearance of the necrotized tissue which occurs in gangrene, one of the symptoms of plague.

An inguinal bubo on the upper thigh of person infected with bubonic plague. Swollen lymph glands (buboes) often occur in the neck, armpit and groin (inguinal) regions of plague victims

Contemporary accounts of the plague are often varied or imprecise. The most commonly noted symptom was the appearance of buboes (or gavocciolos) in the groin, the neck and armpits, which oozed pus and bled when opened.^[28] Boccaccio's description is graphic:

"In men and women alike it first betrayed itself by the emergence of certain tumours in the groin or armpits, some of which grew as large as a common apple, others as an egg...From the two said parts of the body this deadly gavocciolo soon began to propagate and spread itself in all directions indifferently; after which the form of the malady began to change, black spots or livid making their appearance in many cases on the arm or the thigh or elsewhere, now few and large, now minute and numerous. As the gavocciolo had been and still was an infallible token of approaching death, such also were these spots on whomsoever they showed themselves."^[29]

Ziegler comments that the only medical detail that is questionable is the infallibility of approaching death, as if the bubo discharges, recovery is possible.^[30]

This was followed by acute fever and vomiting of blood. Most victims died within two to seven days after infection. David Herlihy identifies another potential sign of the plague: freckle-like spots and rashes^[31] which could be the result of flea-bites.

Some accounts, like that of Louis Heyligen, a musician in Avignon who died of the plague in 1348, noted a distinct form of the disease which infected the lungs and led to respiratory problems^[28] and which is identified with pneumonic plague.

"It is said that the plague takes three forms. In the first people suffer an infection of the lungs, which leads to breathing difficulties. Whoever has this corruption or contamination to any extent cannot escape but will die within two days. Another form...in which boils erupt under the armpits,...a third form in which people of both sexes are attacked in the groin."^[32]

Causes[link]

Yersinia pestis (200x magnification). The bacterium which causes bubonic plague .^[33]

The Oriental rat flea (Xenopsylla cheopis) engorged with blood after a blood meal. This species of flea is the primary vector for the transmission of Yersinia pestis the organism responsible for bubonic plague in most plague epidemics. Both male and female fleas feed on blood and can transmit the infection.

Oriental rat flea (Xenopsylla cheopis) infected with the Yersinia pestis bacterium which appears as a dark mass in the gut. The foregut (proventriculus),of this flea is blocked by a Y. pestis biofilm; when the flea attempts to feed on an uninfected host Y. pestis is regurgitated into the wound, causing infection.

Medical knowledge had stagnated during the Middle Ages. The most authoritative account at the time came from the medical faculty in Paris in a report to the king of France that blamed the heavens, in the form of a conjunction of three planets in 1345 that caused a "great pestilence in the air".^[34] This report became the first and most widely circulated of a series of "plague tracts" that sought to give advice to sufferers. That the plague was caused by bad air became the most widely accepted theory. The word plague had no special significance at this time, and only the recurrence of outbreaks during the Middle Ages gave it the name that has become the medical term.

The importance of hygiene was recognised only in the nineteenth century; until then it was common that the streets were filthy, with live animals of all sorts around and human parasites abounding. A transmissible disease will spread easily in such conditions. One development as a result of the Black Death was the establishment of the idea of quarantine in Dubrovnik in 1377 after continuing outbreaks.^{[citation needed]}

The dominant explanation for the Black Death is the plague theory, which attributes the outbreak to Yersinia pestis, also responsible for an epidemic that began in southern China in 1865, eventually spreading to India. The investigation of the pathogen that caused the 19th-century plague was begun by teams of scientists who visited Hong Kong in 1894, among whom was Alexandre Yersin, after whom the pathogen was named Yersinia pestis.^[35] The mechanism by which Y. pestis was usually transmitted was established in 1898 by Paul-Louis Simond and was found to involve the bites of fleas whose midguts had become obstructed by replicating Y. pestis several days after feeding on an infected host. This blockage results in starvation and aggressive feeding behaviour by the fleas, which repeatedly attempt to clear their blockage by regurgitation, resulting in thousands of plague bacteria being flushed into the feeding site, infecting the host. The bubonic plague mechanism was also dependent on two populations of rodents: one resistant to the disease, which act as hosts, keeping the disease endemic, and a second that lack resistance. When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic.^[35]

The historian Francis Aidan Gasquet, who had written about the 'Great Pestilence' in 1893^[36] and suggested that "it would appear to be some form of the ordinary Eastern or bubonic plague" was able to adopt the epidemiology of the bubonic plague for the Black Death for the second edition in 1908, implicating rats and fleas in the process, and his interpretation was widely accepted for other ancient and medieval epidemics, such as the Justinian plague that was prevalent in the Eastern Roman Empire from 541 to 700 AD.^[35]

More recently other forms of plague have been implicated. The modern bubonic plague has a mortality rate of 30 to 75 percent and symptoms including fever of 38–41 °C (101–105 °F), headaches, painful, aching joints, nausea and vomiting, and a general feeling of malaise. If untreated, of those that contract the bubonic plague, 80 percent die within eight days.^[37] Pneumonic plague has mortality rate of 90 to 95 percent. Symptoms include fever, cough, and blood-tinged sputum. As the disease progresses, sputum becomes free flowing and bright red. Septicemic plague is the least common of the three forms, with a mortality rate close to 100 percent. Symptoms are high fevers and purple skin patches (purpura due to disseminated intravascular coagulation). In cases of pneumonic and particularly septicemic plague the progress of the disease is so rapid that there would often be no time for the development of the enlarged lymph nodes that were noted as buboes.^[38]

"Many modern scholars accept that the lethality of the Black Death stemmed from the combination of bubonic and pneumonic plague with other diseases and warn that every historical mention of 'pest' was not necessarily bubonic plague...In her study of 15th Century outbreaks, Ann Carmichael states that worms, the pox, fevers and dysentery clearly accompanied bubonic plague."^[39]

Alternative explanations[link]

Plague victims being blessed, shown with symptoms from a late 14th century manuscript Omne Bonum by James le Palmer

This interpretation was first significantly challenged by the work of British bacteriologist J. F. D. Shrewsbury in 1970, who noted that the reported rates of mortality in rural areas during the 14th century pandemic were inconsistent with the modern bubonic plague, leading him to conclude that contemporary accounts were exaggerations.^[35] In 1984 zoologist Graham Twigg produced the first major work to challenge the bubonic plague theory directly, and his doubts about the identity of the Black Death have been taken up by a number of authors, including Samuel K. Cohn, Jr. (2002), David Herlihy (1997), and Susan Scott and Christopher Duncan (2001).^[35]

It is recognised that an epidemiological account of the plague is as important as an identification of symptoms, but researchers are hampered by the lack of reliable statistics from this period. Most work has been done on the spread of the plague in England, and even estimates of overall population at the start vary by over 100% as no census was undertaken between the Domesday Book and 1377.^[40] Estimates of plague victims are usually extrapolated from figures for the clergy.

In addition to arguing that the rat population was insufficient to account for a bubonic plague pandemic, sceptics of the bubonic plague theory point out that the symptoms of the Black Death are not unique (and arguably in some accounts may differ from bubonic plague); that transference via fleas in goods was likely to be of marginal significance and that the DNA results may be flawed and might not have been repeated elsewhere, despite extensive samples from other mass graves.^[35] Other arguments include the lack of accounts of the death of rats before outbreaks of plague between the 14th and 17th centuries; temperatures that are too cold in northern Europe for the survival of fleas; that, despite primitive transport systems, the spread of the Black Death was much faster than that of modern bubonic plague; that mortality rates of the Black Death appear to be very high; that, while modern bubonic plague is largely endemic as a rural disease, the Black Death indiscriminately struck urban and rural areas; and that the pattern of the Black Death, with major outbreaks in the same areas separated by five to fifteen years, differs from modern bubonic plague, which often becomes endemic for decades, flaring up on an annual basis.^[35]

Walløe complains that all of these authors "take it for granted that Simond's infection model, black rat → rat flea → human, which was developed to explain the spread of plague in India, is the only way an epidemic of Yersinia pestis infection could spread", whilst pointing to several other possibilities.^[41]

Anthrax skin lesion

A variety of alternatives to the Y. pestis have been put forward. Twigg suggested that the cause was a form of anthrax and N. F. Cantor (2001) thought it may have been a combination of anthrax and other pandemics. Scott and Duncan have argued that the pandemic was a form of infectious disease that characterise as hemorrhagic plague similar to Ebola. Archaeologist Barney Sloane has argued that there are insufficient evidence of the extinction of large number of rats in the archaeological record of the medieval waterfront in London and that the plague spread too quickly to support the thesis that the Y. pestis was spread from fleas on rats and argues that transmission must have been person to person.^[42][43] However, no single alternative solution has achieved widespread acceptance.^[35] Many scholars arguing for the Y. pestis as the major agent of the pandemic, suggest that its extent and symptoms can be explained by a combination of bubonic plague with other diseases, including typhus, smallpox and respiratory infections. In addition to the bubonic infection, others point to additional septicemic (a type of "blood poisoning") and pneumonic (an airborne plague that attacks the lungs before the rest of the body) forms of the plague, which lengthen the duration of outbreaks throughout the seasons and help account for its high mortality rate and additional recorded symptoms.^[28]

DNA evidence[link]

Skeletons in a mass grave from 1720–1721 in Martigues, France, yielded molecular evidence of the orientalis strain of Yersinia pestis, the organism responsible for bubonic plague. The second pandemic of bubonic plague was active in Europe from AD 1347, the beginning of the Black Death, until 1750.

In October 2010 the open-access scientific journal PLoS Pathogens published a paper by a multinational team who undertook a new investigation into the role of Yersinia pestis in the Black Death following the disputed identification by Drancourt & Raoult in 1998.^[44] Their surveys tested for DNA and protein signatures specific for Y. pestis in human skeletons from widely distributed mass graves in northern, central and southern Europe that were associated archaeologically with the Black Death and subsequent resurgences. The authors concluded that this new research, together with prior analyses from the south of France and Germany

"...ends the debate about the etiology of the Black Death, and unambiguously demonstrates that Y. pestis was the causative agent of the epidemic plague that devastated Europe during the Middle Ages."^[45]

The study also found that there were two previously unknown but related clades (genetic branches) of the Y. pestis genome associated with medieval mass graves. These clades (which are thought to be extinct) were found to be ancestral to modern isolates of the modern Y. pestis strains Orientalis and Medievalis, suggesting that the plague may have entered Europe in two waves. Surveys of plague pit remains in France and England indicate that the first variant entered Europe through the port of Marseille around November 1347 and spread through France over the next two years, eventually reaching England in the spring of 1349, where it spread through the country in three epidemics. Surveys of plague pit remains from the Dutch town of Bergen op Zoom showed that the Y. pestis genotype responsible for the pandemic that spread through the Low Countries from 1350 differed from that found in Britain and France, implying that Bergen op Zoom (and possibly other parts of the southern Netherlands) was not directly infected from England or France in 1349 and suggesting that a second wave of plague, different from those in Britain and France, may have been carried to the Low Countries from Norway, the Hanseatic cities or another site.^[45]

The results of the Haensch study have since been confirmed and amended. Based on genetic evidence derived from Black Death victims in the East Smithfield burial site in England, Schuenemann et al. in 2011 further conclude "that the Black Death in medieval Europe was caused by a variant of Y. pestis that may no longer exist."^[46] A study published in Nature in October 2011 sequenced the genome of Y. pestis from plague victims and indicated that the strain that caused the Black Death is ancestral to most modern strains of the disease.^[47]

Consequences[link]

Death toll[link]

Citizens of Tournai bury plague victims

Figures for the death toll vary widely by area and from source to source as new research and discoveries come to light. It killed an estimated 75 million–200 million people in the 14th century.^[48][49][50] According to medieval historian Philip Daileader in 2007:

The trend of recent research is pointing to a figure more like 45 percent to 50 percent of the European population dying during a four-year period. There is a fair amount of geographic variation. In Mediterranean Europe, areas such as Italy, the south of France and Spain, where plague ran for about four years consecutively, it was probably closer to 75 percent to 80 percent of the population. In Germany and England ... it was probably closer to 20 percent.^[51]

The most widely accepted estimate for the Middle East, including Iraq, Iran and Syria, during this time, is for a death rate of about a third.^[52] The Black Death killed about 40% of Egypt's population.^[53] Half of Paris's population of 100,000 people died. In Italy, Florence's population was reduced from 110,000 or 120,000 inhabitants in 1338 to 50,000 in 1351. At least 60 percent of Hamburg's and Bremen's population perished.^[54] Before 1350, there were about 170,000 settlements in Germany, and this was reduced by nearly 40,000 by 1450.^[55] In 1348, the plague spread so rapidly that before any physicians or government authorities had time to reflect upon its origins, about a third of the European population had already perished. In crowded cities, it was not uncommon for as much as 50 percent of the population to die. Europeans living in isolated areas suffered less, whereas monks and priests were especially hard hit since they cared for the Black Death's victims.^[56]

Persecutions[link]

Jews are burned alive during the Black Death

Because 14th century healers were at a loss to explain the cause, Europeans turned to astrological forces, earthquakes, and the poisoning of wells by Jews as possible reasons for the plague's emergence.^[14] The governments of Europe had no apparent response to the crisis because no one knew its cause or how it spread. The mechanism of infection and transmission of diseases was little understood in the 14th century; many people believed only God's anger could produce such horrific displays.

There were many attacks against Jewish communities.^[57] In August 1349, the Jewish communities of Mainz and Cologne were exterminated. In February of that same year, the citizens of Strasbourg murdered 2,000 Jews.^[57] By 1351, 60 major and 150 smaller Jewish communities were destroyed.^[58] The Brotherhood of the Flagellants, a movement said to number up to 800,000, reached its peak of popularity.^[59]

In culture[link]

Pieter Bruegel's The Triumph of Death (c. 1562) reflects the social upheaval and terror that followed the plague which devastated medieval Europe

The Black Death had a profound impact on art and literature throughout the generation that experienced it. Much of the most useful manifestations of the Black Death in literature, to historians, comes from the accounts of its chroniclers. Some of these chroniclers were famous writers, philosophers and rulers such as Boccaccio and Petrarch. Their writings, however, did not reach the majority of the European population. Petrarch's work was read mainly by wealthy nobles and merchants of Italian city-states. He wrote hundreds of letters and vernacular poetry, and passed on to later generations a revised interpretation of courtly love.^[60] There was one troubadour, writing in the lyric style long out of fashion, who was active in 1348. Peire Lunel de Montech composed the sorrowful sirventes "Meravilhar no·s devo pas las gens" during the height of the plague in Toulouse.

They died by the hundreds, both day and night, and all were thrown in ... ditches and covered with earth. And as soon as those ditches were filled, more were dug. And I, Agnolo di Tura ... buried my five children with my own hands ... And so many died that all believed it was the end of the world.

—The Plague in Siena: An Italian Chronicle^[61]

How many valiant men, how many fair ladies, breakfast with their kinfolk and the same night supped with their ancestors in the next world! The condition of the people was pitiable to behold. They sickened by the thousands daily, and died unattended and without help. Many died in the open street, others dying in their houses, made it known by the stench of their rotting bodies. Consecrated churchyards did not suffice for the burial of the vast multitude of bodies, which were heaped by the hundreds in vast trenches, like goods in a ships hold and covered with a little earth.

—Giovanni Boccaccio^[62]

The Great Plague of London, in 1665, killed up to 100,000 people

An epidemic of plague dies out after a few months because it has no host in which the bacteria can survive. However that does not mean that there is not somewhere some surviving infection, in a rodent or flea or warm place, that acts as a reservoir so that sooner or later it breaks out again.^[63]

The plague repeatedly returned to haunt Europe and the Mediterranean throughout the 14th to 17th centuries.^[64] According to Biraben, plague was present somewhere in Europe in every year between 1346 and 1671.^[65] The Second Pandemic was particularly widespread in the following years: 1360–1363; 1374; 1400; 1438–1439; 1456–1457; 1464–1466; 1481–1485; 1500–1503; 1518–1531; 1544–1548; 1563–1566; 1573–1588; 1596–1599; 1602–1611; 1623–1640; 1644–1654; and 1664–1667.^[66] According to Geoffrey Parker, "France alone lost almost a million people to plague in the epidemic of 1628–31."^[67]

In England, in the absence of census figures, historians propose a range of pre-incident population figures from as high as 7 million to as low as 4 million in 1300,^[68] and a post-incident population figure as low as 2 million.^[69] By the end of 1350 the Black Death subsided, but it never really died out in England. Over the next few hundred years, there were further outbreaks in 1361–62, 1369, 1379–83, 1389–93, and throughout the first half of the 15th century.^[70] An outbreak in 1471 took as much as 10–15 percent of the population, while the death rate of the plague of 1479–80 could have been as high as 20 percent.^[71] The most general outbreaks in Tudor and Stuart England seem to have begun in 1498, 1535, 1543, 1563, 1589, 1603, 1625, and 1636, and ended with the Great Plague of London in 1665.^[72]

Plague Riot in Moscow in 1771. During the course of the city's plague, between 50,000 and 100,000 died (1/6 to 1/3 of its population).

In 1466, perhaps 40,000 people died of plague in Paris.^[73] During the 16th and 17th centuries, plague visited Paris for almost one year out of three.^[74] The Black Death ravaged Europe for three years before it continued on into Russia, where the disease hit somewhere once every five or six years from 1350 to 1490.^[75] Plague epidemics ravaged London in 1563, 1593, 1603, 1625, 1636, and 1665,^[76] reducing its population by 10 to 30% during those years.^[77] Over 10% of Amsterdam's population died in 1623–1625, and again in 1635–1636, 1655, and 1664.^[78] There were twenty-two outbreaks of plague in Venice between 1361 and 1528.^[79] The plague of 1576–1577 killed 50,000 in Venice, almost a third of the population.^[80] Late outbreaks in central Europe included the Italian Plague of 1629–1631, which is associated with troop movements during the Thirty Years' War, and the Great Plague of Vienna in 1679. Over 60 percent of Norway's population died from 1348 to 1350.^[81] The last plague outbreak ravaged Oslo in 1654.^[82]

In the first half of the 17th century a plague claimed some 1,730,000 victims in Italy, or about 14% of the population.^[83] In 1656 the plague killed about half of Naples' 300,000 inhabitants.^[84] More than 1,250,000 deaths resulted from the extreme incidence of plague in 17th century Spain.^[85] The plague of 1649 probably reduced the population of Seville by half.^[86] In 1709–1713, a plague epidemic that followed the Great Northern War (1700–1721, Sweden v. Russia and allies)^[87] killed about 100,000 in Sweden,^[88] and 300,000 in Prussia.^[86] The plague killed two-thirds of the inhabitants of Helsinki,^[89] and claimed a third of Stockholm's population.^[90] Europe's last major epidemic occurred in 1720 in Marseilles.^[81]

Worldwide distribution of plague-infected animals 1998

The Black Death ravaged much of the Islamic world.^[91] Plague was present in at least one location in the Islamic world virtually every year between 1500 and 1850.^[92] Plague repeatedly struck the cities of North Africa. Algiers lost 30,000–50,000 to plague in 1620–21, and again in 1654–57, 1665, 1691, and 1740–42.^[93] Plague remained a major event in Ottoman society until the second quarter of the 19th century. Between 1701 and 1750, 37 larger and smaller plague epidemics were recorded in Constantinople, and 31 between 1751 and 1800.^[94] Baghdad has suffered severely from visitations of the plague, and sometimes two-thirds of its population has been wiped out.^[95]

Third plague pandemic[link]

The Third plague pandemic (1855–1959) started in China in the middle of the 19th century, spreading plague to all inhabited continents and killing 10 million people in India alone.^[96] There were twelve plague outbreaks in Australia between 1900 and 1925 resulting in well over 1000 deaths, mainly in Sydney. This led to the establishment of a Public Health Department there which undertook some leading edge research on plague transmission from rat fleas to humans via the bacillus Yersinia pestis.^[97]

The first North American plague epidemic was the San Francisco plague of 1900–1904, followed by another outbreak in 1907–1908.^[98] From 1944 through 1993, 362 cases of human plague were reported in the United States; approximately 90 percent of these occurred in four western states; Arizona, California, Colorado, and New Mexico.^[99] Plague was confirmed in the United States from nine western states during 1995.^[100]

The plague bacterium could develop drug-resistance and again become a major health threat. The ability to resist many of the antibiotics used against plague has been found so far in only a single case of the disease in Madagascar, in 1995.^[101]

Justin Drew Bieber ( /ˈbiːbər/ BEE-bər, born March 1, 1994)^[2] is a Canadian Pop/R&B singer-songwriter, musician, and actor.^[3][5] Bieber was discovered in 2008 by Scooter Braun,^[8] who came across Bieber's videos on YouTube and later became his manager. Braun arranged for him to meet with Usher in Atlanta, Georgia, and Bieber was soon signed to Raymond Braun Media Group (RBMG), a joint venture between Braun and Usher,^[9] and then to a recording contract with Island Records offered by L.A. Reid.^[6][10] Bieber's debut single, "One Time", was released in 2009 and peaked in the top twenty in Canada and charted in the top thirty in several international markets. His debut album, the seven-track EP My World, followed in November 2009, and was soon certified platinum in the United States. He became the first artist to have seven songs from a debut album chart on the Billboard Hot 100.^[11]

Bieber's first full-length studio album, My World 2.0, was released in March 2010. It debuted at number one or within the top ten in several countries and was certified platinum in the United States. It was preceded by the worldwide top-ten single, "Baby". The music video of "Baby" is currently ranked as the most viewed and most discussed YouTube video.^[12] Bieber followed up the release of his debut album with his first headlining tour, the My World Tour, the remix albums My Worlds Acoustic and Never Say Never – The Remixes, and the 3D biopic-concert film Justin Bieber: Never Say Never, that nearly matched the record for the biggest opening weekend gross for a concert-film. Bieber released his second studio album, Under the Mistletoe, in November 2011, which debuted at number one on the Billboard 200. Bieber has received numerous awards, including Artist of the Year at the 2010 American Music Awards, and has been nominated for such awards as Best New Artist and Best Pop Vocal Album at the 53rd Grammy Awards. In 2012, Bieber was named Forbes 3rd most powerful celebrity in the world, earning $55 million. As of May 2012, Bieber has sold 15 million albums.^[13]

Early life[link]

Bieber was born on March 1, 1994, in London, Ontario in St Joseph's Hospital,^[14][15] and was raised in Stratford, Ontario.^[16] Bieber's mother, Patricia Lynn "Pattie" Mallette, was 18 years old when she became pregnant. Mallette, originally from Stratford, raised her son with the help of her parents, Bruce and Diane.^[17] Mallette worked a series of low-paying office jobs, raising Bieber as a single mother in low-income housing. Bieber has maintained contact with his father, Jeremy Jack Bieber, who married another woman and had two children.^[18][19][20] Bieber's great-grandfather was from Germany.^[21] Bieber's mother's ancestry is French Canadian.^[22] Bieber attended a French immersion elementary school in Stratford called Jeanne Sauvé Catholic School.^[17]

During his childhood, Bieber was interested in hockey, soccer, and chess; he often kept his musical aspirations to himself.^[18] As he grew up, Bieber taught himself to play the piano, drums, guitar, and trumpet.^[16][23] In early 2007, when he was twelve, Bieber sang Ne-Yo's "So Sick" for a local singing competition in Stratford and was placed second.^[6][23] Mallette posted a video of the performance on YouTube for their family and friends to see. She continued to upload videos of Bieber singing covers of various R&B songs, and Bieber's popularity on the site grew.^[10] Chris Hicks, Bieber's A&R at Island/Def Jam, explained the young artist's huge online following to HitQuarters by saying:

"He was doing something different. He was an attractive white kid singing very soulful R&B hits. That set him apart immediately from anyone in his range because no one was covering or singing these kind of records. But equally important was that you believed in these songs – it was real. And you wanted to hear more."^[24]

Career[link]

[edit] 2008–09: Discovery and My World

While searching for videos of a different singer, Scooter Braun, a former marketing executive of So So Def, clicked on one of Bieber's 2007 videos by accident.^[18] Impressed, Braun tracked down the theater Bieber was performing in, located Bieber's school, and finally contacted Mallette. Mallette was reluctant because of Braun's Jewish religion; she remembered praying, "God, I gave him to you. You could send me a Christian man, a Christian label! ... you don’t want this Jewish kid to be Justin’s man, do you?"^[18] However, after praying with her church elders and receiving their encouragement, she permitted Braun to fly Bieber, then 13,^[10] to Atlanta, Georgia, to record demo tapes.^[18] A week after arriving, Bieber sang for R&B singer/songwriter Usher.^[25] Bieber was soon signed to Raymond Braun Media Group (RBMG), a joint venture between Braun and Usher.^[9] Justin Timberlake was also reportedly in the running to sign Bieber, but lost the bidding war to Usher.^[9][26] Usher then sought assistance in finding a label home for the artist from then manager Chris Hicks, who helped engineer an audition with his contact Antonio L.A. Reid of Island Def Jam Music Group.^[24] Reid signed Bieber to Island Records in October 2008 (resulting in a joint venture between RBMG and Island Records) and appointed Hicks as executive Vice-President of Def Jam where he would be able manage Bieber's career at the label.^{[6][9][10][24]} At that point, Bieber and his mother moved to Atlanta temporarily, also the home of Usher and Braun, to record and get counseling from Braun.^[9] Braun became Bieber's manager.^[10]

Justin Bieber has a higher score on the Klout online "influence" scale than Barack Obama or The Dalai Lama.^[78] According to Jan Hoffman of The New York Times, part of Bieber's appeal stems from his YouTube channel. Long before he released his EP, My World, in mid-November, the YouTube videos attracted millions of views.^[18] Braun recognized the appeal. Prior to flying him to Atlanta, Braun wanted to "build him up more on YouTube first" and had Bieber record more home videos for the channel. "I said: 'Justin, sing like there’s no one in the room. But let's not use expensive cameras.' We'll give it to kids, let them do the work, so that they feel like it's theirs", recalled Braun.^[18] Bieber continues to upload videos to the same channel and has opened a Twitter account, from which he interacts with fans regularly;^[10] his account was reported in November 2010 to have over 6 million followers.^[79] Since then he has been consistently gaining followers at an average of 24,000 per day.^[80] The accounts also serve marketing purposes; for example, Bieber's music video for "One Time" only began selling quickly after it was uploaded to YouTube.^[81]
