Little is known of the pre-Islamic religions of Arabia, but it is known that the Arabs worshiped a number of gods such as al-Lat, Manat, al-Uzza and Hubal, with the most important being Allah (God).[16] There were also Jewish and Christian communities in Arabia and aspects of Arab religion reflected their influence.[16] Pilgrimage was a major part of Arabian paganism, and one of the most important pilgrimage sites was Mecca, which housed the Kaaba, considered an especially holy place to visit.[16] Mohammad, a merchant of Mecca, started to have visions in which he claimed that the Archangel Gabriel had told him that he was the last of the prophets continuing the work of Jesus Christ and the prophets of Tanakh.[17] After coming into conflict with the elite of Mecca, Mohammad fled to the city of Yathrib, which was renamed Medina.[17] At Yathrib, Mohammad founded the first Islamic state and by 630 conquered Mecca.[17]
