when was christianity created

Christianity was created in the 1st century AD, emerging from the teachings and life of Jesus of Nazareth, a Jewish preacher in the Roman province of Judea. The religion is generally considered to have begun after the death and resurrection of Jesus, around AD 30–33. His followers believed him to be the Messiah and the Son of God, and this belief distinguished Christianity from Judaism and other religions. The earliest Christians were originally a Jewish sect, and the movement gradually separated from Judaism over the first and second centuries. Christianity's key doctrines, including the belief in Jesus' resurrection and salvation through faith in him, became established as defining elements of the new religion. Christianity officially grew and developed through the missionary work of apostles such as Paul, spreading throughout the Roman Empire and beyond in the centuries following Jesus' death. By the 4th century, it had grown significantly and was legalized by the Roman Emperor Constantine in AD 313, eventually becoming the state religion of the Roman Empire by around AD 380. In summary, Christianity originated around AD 30–33 with the ministry and resurrection of Jesus Christ and progressively developed as a distinct religion over the subsequent decades and centuries.
