Accession Day is a holiday in India's northernmost state, Jammu and Kashmir, commemorating 26 October 1947, when Maharaja Hari Singh signed of the Instrument of Accession, in which Jammu and Kashmir joined the Dominion of India. Festivities of the day include holding rallies, bursting of firecrackers, singing India's national anthem, and raising the flag of India. In some areas, the festivities are as big as those of Diwali. However, Pro-Pakistan Islamic terrorists, call for the observance of a "Black Day" following "Accession Day" in order to express their disapproval of the Indian Army entering into Kashmir on 27 October 1947, as requested by Sheikh Abdullah to drive out Pathan tribesmen who had invaded the region.
