Pakistan Day (Urdu: یوم پاکستان) or Pakistan Resolution Day, also Republic Day, is a national holiday in Pakistan commemorating the Lahore Resolution passed on 23 March 1940. The Muslim League held its annual session at Minto Park led by Muhammad Ali Jinnah and other Founding Fathers in Lahore, Punjab, that lasted from 22 to 24 March 1940. The day celebrates the adoption of the Pakistan resolution by the All India Muslim League at the Minar-e-Pakistan that called for establishing an independent state comprising provinces with Muslim majority region of British controlled territories in India. A resolution was passed saying that Muslims in India wanted independence and separate homeland.
The resolution was moved by Abul Kashem Fazlul Huq (26 October 1873 – 27 April 1962), often called Sher-e-Bangaal, passed on 24 March and had its signatures from the Founding Fathers of Pakistan. Since then, the day is celebrated annually throughout the country as a public holiday. The Pakistan Armed Forces usually hold a military parade to celebrate the event.
No constitutional plan would be workable or acceptable to the Muslims unless geographical contiguous units are demarcated into regions which should be so constituted with such territorial readjustments as may be necessary. That the areas in which the Muslims are numerically in majority as in the North-Western and Eastern zones of India should be grouped to constitute independent states in which the constituent units shall be autonomous and sovereign.
