Another answer from our community:First of all he was a Roman Emperor. Second he was a profound supporter of the Christian Church and issued the Edict of Milan in 313 C.E./A.D. which made Christianity an accepted religion in the Roman Empire.
For the most part, Constantine retained most of the sweeping reforms introduced by his predecessor, Diocletian, and which restructured the Roman Empire: the doubling in the number of provinces of the empire and the their grouping into 12 dioceses and the doubling of the size of the imperial bureaucracy. To address the problem of hyperinflation which had plagued the em[ire, Constantine temporarily dropped the main silver coin, the denarius, and concentrated on minting a gold coin the aureus). To do this he resorted to confiscating the treasuries of temple and their gold statues to smelt gold. Historians disagree on whether the Aureus was introduced by Constantine or his predecessor. The problem of hyperinflation had been caused by decades of debasement of the Roman coins (i.e. the reduction of their precious metal content. This devalued the Roman coins and caused inflation. The aureus had a high content of gold and was never debased over the next centuries. This, over the long run, resolved the problem of inflation. Historians also disagree on whether a military reform of this period was carried out by Constantine or Diocletian. Previously the Roman Army had legions which were stationed in the provinces, particularly the frontier ones, and were under the command of provincial governors. The army was now divided into frontier troops, the limitanei, and the comitatus, the field army. The task of the limitanei was to respond to smaller scale hold attacks on the frontier. The comitatus supported the limitanei when there were larger scale invasions, carried out large scale operations in foreign territories. The comitatus and was composed of the legiones (legions) comitatenses . They were regional units stationed in each of the new administrative regions created by Diocletian (the dioceses), further back from the frontiers and near cities. They were mobile units and they were more heavily armed. They could be deployed rapidly. The size of the legions was decreased from some 5,000 to 1,000 and their number was increased. Constantine favoured Christianity. With the Edict of Milan, issued together with his co-emperor Licinius in 313, he finalised the termination of the Great persecution of the Christians which had been decreed by the Edict of Toleration by the emperor Galerius two years earlier. C onstantine built Christian churches, most notably, the original Basilica of St Peter's in Rome, the St John Lateran's Basilica (the city of Rome's first Cathedral and the original residence of the Popes), the Church of the Holy Apostles in Constantinople and Church of the Holy Sepulchre in Jerusalem. He convened synods and ecumenical councils to mediate disputes between rival Christian doctrines, and initiating the tradition of Roman emperors convening such meetings.He promoted Christians in the imperial bureaucracy.
Crusades had a major impact on the building of castles as many large castles were built across Europe. The crusades were expensive and led to the creation of governmental processes to asses and collect taxes. In turn, this led to the current taxation system that has now been adopted around the world.
Might I add that this was in 330 A.D. (C.E.) and is now Istanbul, a major (but not capitol) city in Turkey.
Constantinople was originally called Byzantium, which is where the name for the Eastern Roman Empire after the Western half fell came from (The Byzantine Empire). It became Constantinople when Constantine converted it to Christianity and improved it. Located on the Bosporus Strait, it was very well placed strategically, with water on three sides and right on many major trade routes.
Constantinople (Greek for "Constantine's city" from the Greek "polis" meaning a city) was the name the Roman Emperor Constantine gave to his new capital which was formerly called Byzantium. The city is now called Istanbul and is a major city in Turkey.
he had to do two things that's all I know.
well, when the Roman Empire split in half, the east side was called Byzantium and the west side fell to barbaric tribes. The major religon of Byzantium was Orthodoxy. i dont really understand your question, but i hope this helps!
Constantine moved the capital of the eastern part of the Roman Empire from Nicomedia (in northwestern Turkey) to the nearby Byzantium, which he redeveloped, renamed Constantinople (city of Constantine) and inaugurated in 330. This new capital was given titles such as "The New, second Rome,' 'Eastern Rome,' 'Alma Roma,' and 'Roma Constantinopolitana.' Propaganda-wise the new capital symbolised the new dawn of the Roman Empire which Constantine rule would usher in. Ancient historians did not actually clarify why Constantine the Great moved the capital of the eastern part of the Roman Empire from Nicomedia (in north-western Turkey) to the nearby Byzantium. One reason might have been that Nicomedia had been designated as the capital of the eastern part of the Roman Empire by the emperor Diocletian who had unleashed the Great Persecution of Christians. A highly likely reason was propaganda, which Constantine was very good at. He even invented a fictitious descent from the family of a previous emperor.to give legitimacy to his quest for power. A new capital named after himself would give him further prestige and act as a symbol of the new dawn for the empire his rule would usher in. Constantine redeveloped the Greek city of Byzantium and renamed it Constantinople (which means the city of Constantine) in 330. The city was also given titles such as "The New, second Rome,' 'Eastern Rome,' 'Alma Roma,' and 'Roma Constantinopolitana.' Byzantium has seven hills like Rome. This created a similarity with Rome and justified the titles mentioned above. Originally Constantine considered Sirmium (in modern day Serbia) for his new capital. Then he opted for Byzantium. Other factors may have helped this choice. This city was on the route between Europe and Asia like Nicomedia, but it was in a better strategic position. The roads from south-western Europe to Asia converged there. It was on the Bosporus, the strait between Europe and Asia, and between the Mediterranean and the Black Sea. Therefore, it also controlled the naval route between these two seas. It was also a city easy to defend. It was on a promontory into the Bosporus. Therefore, it had water on two sides. The Golden Horn, an inlet of the Bosporus meant that there was water on the third side as well. The hilly terrain helped to defend the part of the city which was not on the seafront or by the Golden Horn. .
