AnswerEmperor Constantine made Christianity an official religion of the empire about 312 CE. It became the official religion of the Roman Empire in the 380s CE.
Constantine established religious tolerance.
AnswerNo. The Edict of Milan in 312 proclaimed universal religious freedom in the Roman empire. After this point, both Christianity and Manichaeism spread rapidly through the empire. However, state patronage for Christianity made the flowering of Manichaeism shortlived.
The first Roman Emperor to accept Christianity was Constantine the Great. He converted to Christianity in the early 4th century, particularly after the Battle of Milvian Bridge in 312 AD, where he reportedly had a vision that influenced his victory. In 313 AD, he issued the Edict of Milan, which granted religious tolerance to Christians and allowed the faith to be practiced openly within the empire. Constantine's support significantly contributed to the spread and eventual establishment of Christianity as a dominant religion in the Roman Empire.
