who moved the capital from rome to constantinople
Byzantium took on the name of Konstantinoupolis ("city of Constantine", Constantinople) after its re-foundation under Roman emperor Constantine I, who transferred the capital of the Roman Empire from Rome to Byzantium in 330 AD and designated his new capital officially as Nova Roma (Νέα Ῥώμη)' New Rome'. During this time, the city was also called' Second Rome',' Eastern Rome', and Roma Constantinopolitana. As the city became the sole remaining capital of the Roman Empire after the fall of the West, and its wealth, population, and influence grew, the city also came to have a multitude of nicknames.
