The Indian National Congress () (INC, often called Congress), is one of two major political parties in India; the other being the Bharatiya Janata Party. Congress was founded in 1885 during the British Raj; its founders include Allan Octavian Hume (a prominent member of the Theosophical Society), Dadabhai Naoroji and Dinshaw Wacha. In the late nineteenth and early to mid-twentieth centuries, Congress became a pivotal participant in the Indian Independence Movement, with over 15 million members and over 70 million participants in its opposition to British colonial rule in India.
