Strictly speaking, Constantine did not make Christianity the state religion of Rome - this did not happen until 391 CE, some sixty years after his death. However, Constantine did set in place the process by which Christianity would inevitably become the state religion. He gave Christianity state patronage and massive financial support, began the persecution of pagans, and stripped the pagan temples of their treasures, humiliating them in the eyes of the faithful. Nevertheless, at the time of his death, the majority of the population had remained faithful to the pagan gods and paganism remained nominally the state religion, or at least on an equal basis with Christianity.

Christianity
Emperor Constantine was instrumental in the conversion of Rome to Christianity in the 4th century. He issued the Edict of Milan in 313 AD, which legalized Christianity and eventually led to its establishment as the state religion.
Constantine, is erroneously known as a Roman emperor who made Christianity the state religion and even converted to it. In reality he made Christianity a legal religion along with all the others and there is no proof except the word of a religious fanatic that he ever converted to Christianity.
