Explanation:

Hagia Sophia was built possibly by Constantin the Great, who moved the capital city of the Roman Empire from Rome to Byzantium, rebuilt by Emperor Constant and finally rebuilt in its actual aspect by Justinian I.

The Roman Code was a compilation of Roman laws in a systemized way, which led to the development of an efficient and centralized administration in the Byzantine Empire.

The Byzantine Empire expanded thanks to millitary campaigns lead by Bellisarius and Narses (Restauration Imperii).
