After Mohtarma Fatima Jinnah was defeated by Ayub Khan in the Pakistani presidential election, 1965, Jinnah established the Pakistan Muslim League (Functional). Pir Pagaro Syed Shah Mardan Shah-II became the head of this political party. He was also nominated as first president of United Muslim League. He was Chief of Pakistan Muslim League-Functional (PML-F), and spiritual leader of the ‘Hur’ Jamaat organization.
In May 2004, PML (Functional) merged with PML (Q) along with other parties to form the united PML.[2]
However, after two months in July 2004, Pir Pagara and the PML (F) parted ways with the united PML citing differences with the Chaudhry brothers and calling the PML, the Jatt league.[3]
In the 2008 Pakistani general election, the PML-F won four seats,[4] and were given one reserved women's seat raising to their total to five National Assembly seats. Additionally, the party won eight provincial assembly seats in Sindh and three in Punjab.
In September 2010 the Pakistan Muslim League (F) and PML-Q united, forming the All Pakistan Muslim League (Pir Pagara).[5][6]
