Ahmadi Muslims, like all religious groups, have been subject to various forms of religious persecution and discrimination since the movement's inception in 1889. The Ahmadiyya sect of Islam emerged from the Sunni tradition of Islam and its adherents believe in all the five pillars and articles of faith required of Muslims. Ahmadis are considered non-Muslims by many mainstream Muslims since they consider Mirza Ghulam Ahmad, founder of the movement, to be the promised Mahdi and Messiah awaited by the Muslims. Ghulam Ahmad's messianic claims are rejected by mainstream Muslims.
The Ahmadis are active translators of the Qur'an and proselytizers for the faith; converts to Islam in many parts of the world first discover Islam through the Ahmadis. However, in a number of countries, Ahmadis have faced strong resistance in many Muslim-dominated nations, as have other faiths. Ahmadis have been considered heretics and non-Muslim, and subjected to persecution and systematic, sometimes state-sanctioned, oppression.
The Second Amendment to the Constitution of Pakistan and Ordinance XX declare Ahmadis to be non-Muslims and further deprive them of religious rights. Hundreds of Ahmadis were killed in 1953 Lahore riots, 1974 Anti-Ahmadiyya riots and May 2010 attacks on Ahmadi mosques in Lahore. The 1974 riots resulted in the largest number of killings of Ahmadis.
For the five million Ahmadis, religious persecution has been particularly severe and systematic in Pakistan, which is the only state to have officially declared that Ahmadis are non-Muslims. Pakistani laws prohibit the Ahmadis from identifying themselves as Muslims, and their freedom of religion has been curtailed by a series of ordinances, Acts and constitutional amendments. When applying for a Pakistani passport, Pakistanis are required to declare that Mirza Ghulam Ahmad was an impostor prophet and his followers are non-Muslims.
