INC) is a political party in India with widespread roots.[16] Founded in 1885, it was the first modern nationalist movement to emerge in the British Empire in Asia and Africa.[a][17] From the late 19th century, and especially after 1920, under the leadership of Mahatma Gandhi, Congress became the principal leader of the Indian independence movement.[18] Congress led India to independence from the United Kingdom,[b][19][c][20] and powerfully influenced other anti-colonial nationalist movements in the British Empire.[d][17]
