Roman Empire

The Roman Empire was a state that controlled the Mediterranean and much of Europe, Western Asia, and North Africa during the classical period. The Roman Republic had previously conquered most of these territories, which became ruled by emperors following triumvir Octavian's rise to power and establishment of a Principate regime in 27 BC. By the 4th century AD the empire split into western and eastern halves. The Western Empire collapsed in 476 AD, while the Eastern Empire endured until the fall of Constantinople in 1453. By 100 BC, the city of Rome had expanded its rule from the Italian peninsula to most of the Mediterranean and beyond. However, it was severely destabilised by civil wars and political conflicts, which culminated.
