Ahmadiyya (Urdu: احمدیہ ), fully known as Ahmadiyya Muslim Community is an Islamic movement founded in the 19th Century by Mirza Ghulam Ahmad who claimed to be the Mahdi and Promised Messiah. Ahmad wanted to restore Islam's original message. It was started before India was split into the modern day states of India, Pakistan and Bangladesh.
In 1914, the movement split into two different groups, over a question of who should become the next Caliph. Both groups still exist today.
