Al-Zulfiqar was an organization in Pakistan. It was formed in 1979 by Murtaza Bhutto and Shahnawaz Bhutto after their father, then- Prime Minister of Pakistan Zulfikar Ali Bhutto, was deposed in a military coup and executed. Al-Zulfiqar was formed to avenge Bhutto's killing by means of armed struggle against the military regime of General Zia-ul-Haq. Zia had deposed the Bhutto regime after mass protests across Pakistan that were related to the dissatisfaction of the masses with the rule of Bhutto (mismanagement of East Pakistan, alleged links of Bhutto to political murders, corruption, economic stagnation as a result of nationalization, deteriortating education system, etc.) in a Military coup in July 1977.
Bhutto was hanged by the Zia regime. Bhutto's two sons, Murtaza Bhutto and Shahnawaz Bhutto went into exile in Afghanistan which was then being ruled by a Soviet-backed communist government. There the two sons formed the Al-Zulfiqar along with hundreds of Pakistan Peoples Party militants who had escaped Zia's persecution.
