Answer:
Explanation:
Justinian is generally thought to be one of the most important rulers of the Eastern Roman Empire. His most significant achievement is considered to be the collection of Roman laws, the Corpus Juris Civilis, which was an important body of law for the Eastern Roman Empire for centuries and laid the foundation for the legislation of several other European countries.
Justinian was responsible for the construction of the Hagia Sophia, the center of Christianity in Constantinople. Even today, the Hagia Sophia is recognized as one of the greatest buildings in the world. Justinian also systematized the Roman legal code that served as the basis for law in the Byzantine Empire.
Some of his most notable achievements include Belisarius and Justinian's reconquering of lost territories, Justinian's Code which unified the empire under a single set of laws, and his Rebuilding of Constantinople into one of the best cities there ever was, after the Nika revolt destroyed most of it.
