Answer 1

Rome was becoming a dangerous place to live, given the rising power of the "barbarians".

Answer 2

Foundation of Constantinople

Licinius' defeat represented the passing of old Rome, and the beginning of the role of the Eastern Roman Empire as a center of learning, prosperity, and cultural preservation. Constantine rebuilt the city of Byzantium, which was renamed Constantinopolis ("Constantine's City" or Constantinople in English), and issued special commemorative coins in 330 to honour the event. He provided the "Second Rome" with a Senate and civic offices similar to those of Rome. The new city was protected by the alleged True Cross, the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city.[187] The figures of old gods were either replaced or assimilated into a framework of Christian symbolism. Constantine built the new Church of the Holy Apostles on the site of a temple to Aphrodite. Generations later there was the story that a Divine vision led Constantine to this spot, and an angel no one else could see, led him on a circuit of the new walls. The capital would often be compared to the 'old' Rome as Nova Roma Constantinopolitana, the "New Rome of Constantinople").[186][188]
