 In the 1940s , as the Indian independence movement intensified , an upsurge of Muslim nationalism helmed by the All @-@ India Muslim League took place , of which Muhammad Ali Jinnah was the most prominent leader . Being a political party to secure the interests of the Muslim diaspora in British India , the Muslim League played a decisive role during the 1940s in the Indian independence movement and developed into the driving force behind the creation of Pakistan as a Muslim state in the South Asia . During a three @-@ day general session of All @-@ India Muslim League from 22 – 24 March 1940 , a formal political statement was presented , known as the Lahore Resolution , which called on for the creation of an independent state for Muslims .
