The Establishment of Christianity: A Gradual Process

Christianity's establishment cannot be pinned to a single date. It emerged from the teachings of Jesus of Nazareth in the 1st century CE. After his crucifixion and reported resurrection, followers spread the message across the Roman Empire. Over centuries, it grew from a persecuted sect to the empire's dominant religion, culminating in Constantine's conversion and the Edict of Thessalonica (380 CE) making it the official state religion.
