The Byzantine Empire (officially, the Roman Empire, Greek: Βασιλεία Ῥωμαίων or Basileia Rhōmaiōn) was a state located in the east of the former Roman Empire, which remained stable even after the collapse of the Western Roman Empire in AD 453. It remained one of the strongest powers of Europe, helping to establish the Empire of the West and the Saxon Empire, as well as influence the establishment of the Kingdom of Pyrdain. However, it lost influence in the Middle East after the independence of the Empire of Aram, leading it to lose regional power status to Aram and the Sassanid Empire, its historical enemy.
