Justinian I, also known as ‘Justinian the Great’ and ‘Saint Justinian the Great’, was a Byzantine (East Roman) Emperor and one of the most influential rulers in the western history. At the time he acquired the throne, the kingdom was weak and Justinian vowed to make it powerful again and rightly so, he set out to reclaim the western half of the empire and successfully won it. His reign is also known famously in the history as the ‘restoration of the Empire’. In his important campaigns, he took Africa back from the Vandals and defeated Goths to make Italy a part of his empire again. He also set out to build countless new churches, monasteries, forts, water reservoirs and bridges. The public loved him as much as it feared him. One of the other biggest achievements of his reign was his decision to order the rewriting of Roman law, called Corpus Juris Civilis. These documents were so modern in their nature that many of the modern civil laws take their inspiration from it.
