Ahmadis believe that the prophecies concerning the Mahdi and the second coming of Jesus have been fulfilled in Mirza Ghulam Ahmad (1835–1908), the founder of the Ahmadiyya Movement. Unlike mainstream Muslims, the Ahmadis do not believe that Jesus is alive in heaven, but that he survived the crucifixion and migrated towards the east where he died a natural death and that Ghulam Ahmad was only the promised spiritual second coming and likeness of Jesus, the promised Messiah and Mahdi. He also claimed to have appeared in the likeness of Krishna and that his advent fulfilled certain prophecies found in Hindu scriptures. He stated that the founder of Sikhism was a Muslim saint, who was a reflection of the religious challenges he perceived to be occurring. Ghulam Ahmad wrote "Barahin-e-Ahmadiyya", in 1880, which incorporated Indian, Sufi, Islamic and Western aspects in order to give life to Islam in the face of the British Raj, Protestant Christianity, and rising Hinduism. He later declared himself the Promised Messiah and the Mahdi following Divine revelations in 1891. Ghulam Ahmad argued that Jesus had appeared 1300 years after the formation of the Muslim community and stressed the need for a current Messiah, in turn claiming that he himself embodied both the Mahdi and the Messiah. Ghulam Ahmad was supported by Muslims who especially felt oppressed by Christian and Hindu missionaries.
