Justinian I

Justinian I or Iustinian I (/dʒʌˈstɪniən/; Latin: Flavius Petrus Sabbatius Iustinianus Augustus, Greek: Φλάβιος Πέτρος Σαββάτιος Ἰουστινιανός Flávios Pétros Sabbátios Ioustinianós) (c. 482 – 14 November 565), traditionally known as Justinian the Great and also Saint Justinian the Great in the Eastern Orthodox Church, was a Byzantine (East Roman) emperor from 527 to 565. During his reign, Justinian sought to revive the empire's greatness and reconquer the lost western half of the historical Roman Empire. Justinian's rule constitutes a distinct epoch in the history of the Later Roman empire, and his reign is marked by the ambitious but only partly realized renovatio imperii, or "restoration of the Empire".

Because of his restoration activities, Justinian has sometimes been called the "last Roman" in modern historiography. This ambition was expressed by the partial recovery of the territories of the defunct western Roman empire. His general, Belisarius, swiftly conquered the Vandal kingdom in North Africa, re-extending Roman control to the Atlantic Ocean. Subsequently Belisarius, Narses, and other generals conquered the Ostrogothic kingdom, restoring Dalmatia, Sicily, Italy, and Rome to the empire after more than half a century of rule by the Ostrogoths. The prefect Liberius reclaimed most of southern Iberia, establishing the province of Spania. These campaigns re-established Roman control over the western Mediterranean, increasing the Empire's annual revenue by over a million solidi. During his reign Justinian also subdued the Tzani, a people on the east coast of the Black Sea that had never been under Roman rule before.

Roman Empire

The Roman Empire (Latin: Imperium Rōmānum; Classical Latin: [ɪmˈpɛ.ri.ũː roːˈmaː.nũː] Ancient and Medieval Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tōn Rhōmaiōn) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The extended city of Rome was the largest city in the world c. 100 BC – c. 400 AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was now unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus, effectively marking the end of the Roman Republic.

Byzantine Empire

The Byzantine Empire, sometimes referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, originally founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the Roman Empire (Ancient Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tôn Rhōmaiōn; Latin: Imperium Romanum), or Romania (Ῥωμανία), and to themselves as "Romans".

Several events from the 4th to 6th centuries mark the period of transition during which the Roman Empire's Greek East and Latin West divided. Constantine I (r. 324–337) reorganised the empire, made Constantinople the new capital, and legalised Christianity. Under Theodosius I (r. 379–395), Christianity became the Empire's official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius (r. 610–641), the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. Thus, although the Roman state continued and Roman state traditions were maintained, modern historians distinguish Byzantium from ancient Rome insofar as it was centred on Constantinople, oriented towards Greek rather than Latin culture, and characterised by Orthodox Christianity.

Empire

An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Spanish Empire, Russian Empire, Byzantine Empire or Roman Empire." An empire can be made solely of contiguous territories such as the Austro-Hungarian Empire, or of territories far remote from the homeland, such as a colonial empire.

Aside from the more formal usage, the term "empire" can also be used to refer to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss) or a group (political bosses). The term "empire" is associated with other words such as imperialism, colonialism, and globalization. Empire is often used to describe a displeasure to overpowering situations. The effects of imperialism exist throughout the world today.

An imperial political structure can be established and maintained in two ways: (i) as a territorial empire of direct conquest and control with force or (ii) as a coercive, hegemonic empire of indirect conquest and control with power. The former method provides greater tribute and direct political control, yet limits further expansion because it absorbs military forces to fixed garrisons. The latter method provides less tribute and indirect control, but avails military forces for further expansion. Territorial empires (e.g., the Mongol Empire and Median Empire) tend to be contiguous areas. The term, on occasion, has been applied to maritime empires or thalassocracies, (e.g., the Athenian and British empires) with looser structures and more scattered territories. Empires are usually larger than kingdoms.

World history

World history, global history or transnational history (not to be confused with diplomatic or international history) is a field of historical study that emerged as a distinct academic field in the 1980s. It examines history from a global perspective. It is not to be confused with comparative history, which, like world history, deals with the history of multiple cultures on a global scale. World historians use a thematic approach, with two major focal points: integration (how processes of world history have drawn people of the world together) and difference (how patterns of world history reveal the diversity of the human experiences).

History

Pre-modern

The study of world history, as distinct from national history, has existed in many world cultures. However, early forms of world history were not truly global, and were limited to only the regions known by the historian.

In Ancient China, Chinese world history, that of China and the surrounding people of East Asia, was based on the dynastic cycle articulated by Sima Qian in circa 100 BC. Sima Qian's model is based on the Mandate of Heaven. Rulers rise when they united China, then are overthrown when a ruling dynasty became corrupt. Each new dynasty begins virtuous and strong, but then decays, provoking the transfer of Heaven's mandate to a new ruler. The test of virtue in a new dynasty is success in being obeyed by China and neighboring barbarians. After 2000 years Sima Qian's model still dominates scholarship, although the dynastic cycle is no longer used for modern Chinese history.
