Pakistan Zindabad is a patriotic slogan used by Pakistanis in displays of Pakistani nationalism. The phrase became popular among the Muslims of British India after the 1933 publication of the "Pakistan Declaration" by Choudhry Rahmat Ali, who argued that the Muslim minority in British India—particularly in the Muslim-majority regions of Punjab, Afghania, Kashmir, Sindh, and Baluchistan—constituted a nation of an irrevocably distinct nature from the rest of India on "religious, social, and historical grounds" owing primarily to the issue of Hindu–Muslim unity. Ali's ideology was adopted by the All-India Muslim League as the "two-nation theory" and ultimately spurred the Pakistan Movement that led to the partition of British India. During this time, "Pakistan Zindabad" became a widely used slogan and greeting within the Muslim League, and following the creation of Pakistan, it was also used as a rallying cry by Muslims who were migrating to the newly independent state from India as well as by those who were already within Pakistan's borders. The slogan is commonly invoked by Pakistani citizens and Pakistani state institutions on national holidays, during times of armed conflict, and on other major occasions.
