Muttahida Quami Movement, generally known as MQM , ("United National Movement" in English) is an progressive liberal secular centre left party in Pakistan (initially on quasi-socialist lines) founded on 11 June 1978 as a student organization of "muhajir" (immigrants), the All Pakistan Muhajir Students Organization or APMSO, at the University of Karachi by Altaf Hussain who continues to remain its chief. Supposedly it represent the majority of immigrants who migrated from India to Pakistan in 1947. APMSO then gave birth to the Muhajir Quami Movement (MQM) on March 1984. From 1992 to 1994, the MQM was the target of the Pakistan Army's Operation Cleanup leaving hundreds of civilians dead. On July 26, 1997, MQM officially removed the term Muhajir from its name, and replaced it with Muttahida ("United"). In 1992, after the operation "Clean up", there was the split with key members of the party: the MQM-H or MQM Haqiqi, the "real" MQM, was born. Since then have not stopped the target killing from both sides. The target killing is getting intensified in Karachi with the military's ongoing counterinsurgency operation in Swat and Malakand. The MQM party is, maybe, the worst enemy of the taliban in Pakistan.
