Conversion of Constantine
Before the Battle of the Milvian Bridge in 312 CE, Constantine experienced a vision of the cross and converted to Christianity, transforming the empire's relationship with the faith.
Outcome
Christianity gained imperial patronage; the Edict of Milan granted toleration, and the church was integrated into the structures of imperial power.
