The Greek East was one of the two main cultural areas of the Roman Empire and began to be ruled by an autonomous imperial court in 286 AD under Diocletian. However, Rome remained the nominal capital of both parts of the empire, and Latin was the state language. When the Western Empire fell and the Roman Senate sent the regalia of the Western Emperor to the Eastern Emperor Zeno in 476 AD, Constantinople (Byzantium in Ancient Greek) was recognized as the seat of the sole Emperor. A process of political Hellenization began and led, among other reforms, to the declaration of Greek as the official language in 610 AD.[31]
