The Lahore Resolution commonly known as the Pakistan Resolution was a political resolution/landmark document formally adopted on 23 March 1940 at Lahore. This resolution asked for greater Muslim autonomy within British India. Before this, the Muslims of sub-continent had no goal and no future in view and Muslim politics remained in the hands of the individuals with conflicting interests and inclinations.
As soon as Lahore Resolution was passed by the Muslim League, the Hindu Press started criticising the Muslim League and declared this resolution as Pakistan Resolution. The Resolution addressed the Muslim question in the political and constitutional context of British India and pointed out to the course of action the Muslim League intended to adopt to secure the Muslim identity, rights and interests. It emphasized the principles that were relevant to modern state system and the political context of British India.
It supported federalism with autonomy for provinces, hoping that the Muslims would be able to exercise power effectively in the Muslim majority provinces which would not only boost the Muslim community but also provide greater opportunity for advancement of Muslim rights and interests.
The day is celebrated in the memory to commemorate the event when the Muslim League drafted the political resolution at the Minar-e-Pakistan that called for establishing an independent federation comprising provinces with Muslim majority located in north-western and north-eastern region of British controlled territories in India (excluding autonomous princely States) on 23 March 1940. Since then, the day is celebrated annually at the national level as a public holiday and the services hold a military parade for the celebration of the event.
