11.2 The Rise of Christianity in the Roman Empire

Christianity emerged as a powerful force in the Roman Empire, transforming from a small Jewish sect to the state religion. Its message of salvation and equality appealed to many, spreading rapidly through Roman infrastructure and trade networks.

The faith faced persecution but ultimately gained imperial favor under Constantine. This shift led to Christianity's integration into Roman society, shaping the empire's cultural and political landscape for centuries to come.
