Answer:
Roman culture did not disappear because the traditions were kept alive by leaders in Constantinople.
Step-by-step explanation:
Thanks to Constantinople, the remaining part of the Roman Empire which became Byzantium, kept the traditions almost for millennia.
The Western Roman Empire preserved the heritage until the coming of the influence of the Renaissance from the Mediterranean.
As Constantine, decided to change the political seat from Rome, he chose Constantinople and founded a capital from which Commerce through the Silk Road flourished.
Constantinople survived all sorts of invasions, since Rome fell to the Visigoths in 410, and it kept to succeed commercially and culturally in one of the richest and prolific regions of the time.
