  China
  China (ⁱ/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.
  The People's Republic of China is a single-party state governed by the Communist Party of China. It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). Its capital city is Beijing. The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.

  Germany
  Germany (ⁱ/ˈdʒɜrməni/), officially the Federal Republic of Germany (German: Bundesrepublik Deutschland, pronounced [ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant] ( listen)), is a federal parliamentary republic in Europe. The country consists of 16 states while the capital and largest city is Berlin. Germany covers an area of 357,021 km² and has a largely temperate seasonal climate. With 81.8 million inhabitants, it is the most populous member state and the largest economy in the European Union. It is one of the major political powers of the European continent and a technological leader in many fields.
  A region named Germania, inhabited by several Germanic peoples, was documented before AD 100. During the Migration Period, the Germanic tribes expanded southward, and established successor kingdoms throughout much of Europe. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation while southern and western parts remained dominated by Roman Catholic denominations, with the two factions clashing in the Thirty Years' War, marking the beginning of the Catholic–Protestant divide that has characterized German society ever since. Occupied during the Napoleonic Wars, the rise of Pan-Germanism inside the German Confederation resulted in the unification of most of the German states into the German Empire in 1871 which was Prussian dominated. After the German Revolution of 1918–1919 and the subsequent military surrender in World War I, the Empire was replaced by the Weimar Republic in 1918, and partitioned in the Treaty of Versailles. Amidst the Great Depression, the Third Reich was proclaimed in 1933. The latter period was marked by Fascism and World War II. After 1945, Germany was divided by allied occupation, and evolved into two states, East Germany and West Germany. In 1990 Germany was reunified.

  Goguryeo
  Goguryeo or Koguryŏ (Korean pronunciation: [koɡuɾjʌ]) was an ancient Korean kingdom located in present day northern and central parts of the Korean Peninsula, southern Manchuria, and southern Russian Maritime province.
  Along with Baekje and Silla, Goguryeo was one of the Three Kingdoms of Korea. Goguryeo was an active participant in the power struggle for control of the Korean peninsula as well as associated with the foreign affairs of neighboring polities in China and Japan.
  The Samguk Sagi, a 12th century CE Goryeo text, indicates that Goguryeo was founded in 37 BC by Jumong, a prince from Buyeo, although there is archaeological and textual evidence that suggests Goguryeo culture was in existence since the 2nd century BCE around the fall of Gojoseon, an earlier kingdom that also occupied southern Manchuria and northern Korea.
  Goguryeo was a major dynasty in Northeast Asia, until it was defeated by a Silla-Tang alliance in 668 CE. After its defeat, its territory was divided among the Unified Silla, Balhae, and Tang dynasty.

  Han Dynasty
  The Han Dynasty (simplified Chinese: 汉朝; traditional Chinese: 漢朝; pinyin: Hàn Cháo; Wade–Giles: Han Ch'ao; IPA: [xân tʂʰɑ̌ʊ̯]) (206 BCE – 220 CE) was an imperial dynasty of China, preceded by the Qin Dynasty (221–207 BCE) and succeeded by the Three Kingdoms (220–280 CE). It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han. It was briefly interrupted by the Xin Dynasty (9–23 CE) of the former regent Wang Mang. This interregnum separates the Han into two periods: the Western Han (206 BCE – 9 CE) and Eastern Han (25–220 CE). Spanning over four centuries, the period of the Han Dynasty is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people" and Chinese characters are referred to as "Han characters".

  Slovakia
  The Slovak Republic (short form: Slovakia ⁱ/sloʊˈvɑːkiə/ or /sləˈvækiə/; Slovak:  Slovensko (help·info), long form  Slovenská republika (help·info)) is a landlocked state in Central Europe. It has a population of over five million and an area of about 49,000 square kilometres (19,000 sq mi). Slovakia is bordered by the Czech Republic and Austria to the west, Poland to the north, Ukraine to the east and Hungary to the south. The largest city is the capital, Bratislava, and the second largest is Košice. Slovakia is a member state of the European Union, NATO, United Nations, OECD and WTO among others. The official language is Slovak, a member of the Slavic language family.
  The Slavs arrived in the territory of present day Slovakia in the 5th and 6th centuries during the migration period. In the course of history, various parts of today's Slovakia belonged to Samo's Empire (the first known political unit of Slavs), Principality of Nitra (as independent polity, as part of Great Moravia and as part of Hungarian Kingdom), Great Moravia, Kingdom of Hungary, the Austro-Hungarian Empire or Habsburg Empire, and Czechoslovakia. A separate Slovak state briefly existed during World War II, during which Slovakia was a dependency of Nazi Germany between 1939 and 1944. From 1945 Slovakia once again became a part of Czechoslovakia. The present-day Slovakia became an independent state on 1 January 1993 after the peaceful dissolution of Czechoslovakia.

• Liu Hui
  Liu Hui (fl. 3rd century) was a mathematician of the state of Cao Wei during the Three Kingdoms period of Chinese history. In 263, he edited and published a book with solutions to mathematical problems presented in the famous Chinese book of mathematics known as The Nine Chapters on the Mathematical Art (九章算术).
  He was a descendant of the Marquis of Zixiang of the Han dynasty, corresponding to current Zixiang township of Shandong province. He completed his commentary to the Nine Chapters in the year 263.
  He probably visited Luoyang, and measured the sun's shadow.
  Along with Zu Chongzhi, Liu Hui was known as one of the greatest mathematicians of ancient China. Liu Hui expressed all of his mathematical results in the form of decimal fractions (using metrological units), yet the later Yang Hui (c. 1238-1298 AD) expressed his mathematical results in full decimal expressions.
  Liu provided commentary on a mathematical proof identical to the Pythagorean theorem. Liu called the figure of the drawn diagram for the theorem the "diagram giving the relations between the hypotenuse and the sum and difference of the other two sides whereby one can find the unknown from the known".

  Marcomanni
  The Marcomanni were a Germanic tribe, probably related to the Buri, Suebi or Suevi.
  Scholars believe their name derives possibly from Proto-Germanic forms of "march" ("frontier, border") and "men".
  The Marcomanni settled in the Main River valley soon after 100 BC. To escape Roman aggression in 9 BC they migrated east to Bohemia, where their king Maroboduus established a powerful kingdom that Augustus perceived as a threat to Rome. Before he could act, however, the war in Illyria intervened. Eventually Maroboduus was deposed and exiled by Catualda (AD 19).
  Tacitus, in the late 1st century mentions (Germania I.42) the Marcommani as being under kings appointed by Rome. [1]
  In the 2nd century AD, the Marcomanni entered into a confederation with other peoples including the Quadi, Vandals, and Sarmatians, against the Roman Empire. This was probably driven by movements of larger tribes, like the Goths. According to the historian Eutropius, the forces of the Emperor Marcus Aurelius battled against the Marcomannic confederation for three years at the fortress of Carnuntum in Pannonia. Eutropius compared the war, and Marcus Aurelius' success against the Marcomanni and their allies, to the Punic Wars. The comparison was apt in that this war marked a turning point and had significant Roman defeats; it caused the death of two Praetorian Guard commanders. The war began in 166, when the Marcomanni overwhelmed the defences between Vindobona and Carnuntum, penetrated along the border between the provinces of Pannonia and Noricum, laid waste to Flavia Solva, and could be stopped only shortly before reaching Aquileia on the Adriatic sea. The war lasted until Marcus Aurelius' death in 180. It would prove to be only a limited success for Rome; the Danube river remained as the frontier of the Empire until the final fall of the West.

  Marcus Aurelius
  Marcus Aurelius (Latin: Marcus Aurelius Antoninus Augustus; 26 April 121 – 17 March 180 AD), was Roman Emperor from 161 to 180 AD. He ruled with Lucius Verus as co-emperor from 161 until Verus' death in 169. He was the last of the "Five Good Emperors", and is also considered one of the most important Stoic philosophers. During his reign, the Empire defeated a revitalized Parthian Empire; Aurelius' general Avidius Cassius sacked the capital Ctesiphon in 164. Aurelius fought the Marcomanni, Quadi, and Sarmatians with success during the Marcomannic Wars, but the threat of the Germanic tribes began to represent a troubling reality for the Empire. A revolt in the East led by Avidius Cassius failed to gain momentum and was suppressed immediately.
  Marcus Aurelius' Stoic tome Meditations, written in Greek while on campaign between 170 and 180, is still revered as a literary monument to a philosophy of service and duty, describing how to find and preserve equanimity in the midst of conflict by following nature as a source of guidance and inspiration.

  Sima Yi
  Sima Yi (179 – September 7, 251) was a general and politician of the state of Cao Wei during the Three Kingdoms era of Chinese history. He is perhaps best known for defending Wei from Zhuge Liang's Northern Expeditions. His success and subsequent rise in prominence paved the way for his grandson Sima Yan's founding of the Jin Dynasty, which would eventually bring an end to the Three Kingdoms era. In 265 after the Jin Dynasty was established, Sima Yi was posthumously honored as Emperor Xuan of Jin with the temple name of Gaozu.
  Sima Yi was one of eight brothers, all of whom were famous due to their lineage. Each of them had a Chinese style name ending with the character Da (達). Because of this, the brothers were known collectively as the "Eight Da of Sima" (司馬八達). This was a term of respect, as other groups of eight talented administrators in previous eras had been referred to in this way. His family resided in Luoyang when Dong Zhuo occupied the city, destroyed it, and moved the capital to Chang'an. Sima Yi's elder brother, Sima Lang led the family to their ancestral home in the Wen district (温縣), and then, correctly predicting that it would become a battlefield, moved them again to Liyang (黎陽). In 194, as Cao Cao did battle with Lü Bu, Sima Yi accompanied his family back to Wen district.
