Byzantium, later renamed Constantinople after him.

Constantinople
Constantine the Great designated Byzantium as his imperial capital, redeveloped and renamed it Constantinople, after himself - Constantinople means city of Constantine. However, this did not lead to the beginning of the Byzantine Empire. In fact, the Byzantine Empire did not actually exist. This is a term which has been coined by historians to indicate the eastern part of the Roman Empire after the fall of the western part of this empire and which became popular in the 19th century. The people in question did not know this term and called their empire Roman Empire. Therefore, it would be more appropriate to talk of a "Byzantine" period. This started about a century later.
The capital of the Eastern Roman Empire was Constantinople, which is present-day Istanbul in Turkey. It was founded by the Roman Emperor Constantine the Great in 330 AD and served as the political, cultural, and economic center of the Byzantine Empire. Constantinople remained the Eastern Roman Empire's capital until it fell to the Ottoman Turks in 1453.
Constantine split the Roman Empire into the Holy Roman Empire and the Byzantine Empire. It should be noted however that the emperor Diocletian (284-305 AD ) made this easier as he was the first to divide the empire into two parts, a western and eastern empire to be ruled separately. The emperors who followed Constantine, Julian and Theodosius I, made permanent the division of the Roman Empire into an eastern and western half.
Constantinople was the capital city of the Eastern Roman Empire, named so after Constantine the Great. It was not an empire.
Constantinople was the capital of the Roman Empire under Emperor Constantine the Great around 330 AD.
the capital of eastern Rome was Constantinople or in other words Byzantium. It was ruled by Constantine
Romulus Augustulus was the last Emperor of the Western Roman Empire. The last Emperor of the eastern Roman Empire (Constantinople) was Constantine XI Palaiologos.
Constantine never had a thing to do with the "eastern" empire or the "western" empire. He moved the capital of the Roman empire to the eastern city of Constantinople. The connotation of eastern and western was not made by the ancients, but is a term invented by historians to clarify the part of the empire they would be writing about. The ancients considered the empire one, and they all considered themselves Roman.
