In 330 C.E., Emperor Constantine founded Constantinople and moved the Roman Empire's capital there. This eventually led to the beginning of the Byzantine Empire.
Answer;
He founded Constantinople and moved the Roman Empire's capital there.

In 330 CE, Emperor Constantine dedicated the new city of Constantinople as the imperial capital of the Roman Empire.

Explanation; 
Constantine was a very significant Roman Emperor, ruling for 32 years.
He consolidated his power, becoming the sole emperor, and brought an end to the turmoil that resulted from the breakdown of Emperor Diocletian's plan for an ongoing tetrarchy. He dedicated the new city of Constantinople as the imperial capital of the Roman Empire.
During his reign the borders of the Roman Empire were maintained, and the economic reforms of Emperor Diocletian were consolidated and also made Christianity to move from its status as a "sometimes persecuted religion" to the favored religion of Roman Empire.
