Christianity originated in the 1st century CE in the region of Judea, part of the Roman Empire. It began as a movement within Judaism, centered around the teachings of Jesus of Nazareth, who is considered the central figure of the faith. His followers believed him to be the Messiah and the Son of God, spreading his teachings after his crucifixion and resurrection. The early Christians formed communities that practiced their faith and shared their beliefs. Key figures, such as the apostles Peter and Paul, played significant roles in spreading Christianity beyond Judea, leading to its growth throughout the Roman Empire and eventually becoming a major world religion.
