Ahmadiyya is an Islamic messianic movement that originated in British India during the late 19th century. It was founded by Mirza Ghulam Ahmad (1835–1908), who claimed to be divinely appointed as both the promised Messiah and the Mahdi expected by Muslims to appear toward the end times.
The movement's core beliefs center on the idea that its founder would bring about the final triumph of Islam through peaceful means. In this capacity, he was also said to embody the expected eschatological figures of other major religious traditions. Adherents of the movement are known as Ahmadi Muslims or Ahmadis.
