The Apostolic Age of the history of Christianity is traditionally the period of the Twelve Apostles, dating from the Great Commission of the Apostles by the resurrected Jesus in Jerusalem c. 33 until the death of the last Apostle, believed to be John the Apostle in Anatolia c. 100. Traditionally, the Apostles are believed to have dispersed from Jerusalem, founding the Apostolic Sees. It holds special significance in Christian tradition as the age of the direct apostles of Jesus Christ. The major primary source for the "Apostolic Age" is the Acts of the Apostles, but its historical accuracy is questioned by some.
