As a result of the conversion of Konstantin, he became more tolerant of Roman Christianity, the church spread to other parts of his empire and it became possible to preach in the public society. Constantine was praised as an emperor who did not make Christianity any longer anti-Roman. If Konstantinus does not transform Rome without transforming it, the church will not be able to get enough footholds in Rome and the western part. His conversion ended the widespread persecution of Christians in the Roman Empire and greatly enhanced the power and influence of Christianity in Rome.
Many historians believe that the transformation of Constantine was for ancient churches, so the Concord of 1801 is an important event for contemporary churches. Since Constantine first recognized and established Christianity in the Roman Empire, a series of agreements and other non-formal agreements created a model between the church and the modern secular society. The effect of this arrangement on the Pope was to give up most of the domination of the church in Europe. As a result, the Vatican City became a unique political organization, but after the years of conflict between churches in the Italian unification between 1869 and 1970.
Constantine's conversion to Christianity led to the legitimization of religion within the Roman Empire. Konstantin integrated his religion into his politics, and in so doing, the influence of Christianity began to promote Roman politics. Due to his conversion, many other people motivated to pursue political progress joined the church, so the transformation of Konstantin promoted the growth of religion.
In the history of Christianity for the first 280 years, Christianity was banned by the Roman Empire and Christians were greatly persecuted. This situation changed after the "transformation" of Roman emperor Constantine. Constantine offered religious tolerance to the Milan Decree in 313 AD, effectively virtually lifted the prohibition of Christianity. Later, in 325 AD, Konstantin called for the Nicene air parliament to try Christian unity. Constantine regarded Christianity as a unified religion of the Roman Empire when the Roman Empire divided and began to divide. This seems to be a positive development for Christian churches, but the result is not positive. Constantine, but he has refused to accept completely the Christian faith, as continued to practice and his many pagan beliefs, expanded to have Christ Church of Constantine and the heir and the true Christian It became a pagan mixture of Rome.
