Muttahida Qaumi Movement generally known as MQM, is the 3rd largest political party and the largest liberal and secular political party of Pakistan. It is generally known as a party which holds immense mobilizing potential in province of Sindh. The student organization, All Pakistan Muhajir Student Organization (APMSO), was founded in 1978 by Altaf Hussain which subsequently gave birth to the Muha
jir Quami Movement in 1984. The organization maintains liberal, progressive and secular stances on many political and social issues. From 1992 to 1999, the MQM was the alleged target of the Pakistan Army's Operation Cleanup leaving thousands of urdu speaking civilians dead. In 1997, the MQM officially removed the term Muhajir (which denotes the party's roots of Urdu-speaking Muslims) from its name, and replaced it with Muttahida ("United"). The MQM is one of few socially liberal political parties in Pakistan and organized the largest rallies in Pakistan in protest of the actions of al-Qaeda on September 11, 2001 demonstrating sympathy with the victims of the terrorist attacks. Mutahida Qaumi Movement (MQM) is the second largest party in Sindh and the traditionally the third largest in the country, however it currently holds fourth highest number of seats in the National Assembly while maintaining its second position in the Sindh Assembly. History
Muhajirs were the Urdu-speaking Muslims who migrated to Pakistan when the country emerged independent from British India in 1947. Karachi was then home to a very diverse set of ethnicities including Urdu and Gujarati speaking immigrants, Punjabis, Pashtuns, Sindhis, Baluchis and foreigners from several South Asian countries. In those times, Muhajirs were advancing in business and bureaucracy but many resented the quota system which facilitated Sindhis in gaining university slots and civil service jobs. It was this very ethnic rivalry that led to Muhajir political mobilizaton, which was further provoked by the stagnant economy and the condition of Biharis in Bangladesh concentration camps.
