The Indian National Congress (INC), also known as the Congress Party, or simply the Congress, is a big tent political party in India. It is one of the two major Indian political parties alongside the Bharatiya Janata Party, and the oldest party in India. Founded on 28 December 1885, it was the first modern nationalist movement to emerge in the British Empire in Asia and Africa. From the late 19th century, and especially after 1920, under the leadership of Mahatma Gandhi, the Congress became the principal leader of the Indian independence movement. The Congress was one of the parties who led India to independence from the United Kingdom, and significantly influenced other anti-colonial nationalist movements in the British Empire.
The INC is a "big tent" party that has been described as sitting on the centre of the Indian political spectrum. The party held its first session in 1885 in Bombay where W.C. Bonnerjee presided over it. After Indian independence in 1947, Congress emerged as a catch-all, Indian nationalist and secular party, dominating Indian politics for the next 50 years. The party's first prime minister, Jawaharlal Nehru, led the Congress to support socialist policies by creating the Planning Commission, introducing Five-Year Plans, implementing a mixed economy, and establishing a secular state. After Nehru's death and the short tenure of Lal Bahadur Shastri, Indira Gandhi became the leader of the party. In the 17 general elections since independence, it has won an outright majority on seven occasions and has led the ruling coalition a further three times, heading the central government for more than 54 years. There have been six prime ministers from the Congress party, the first being Jawaharlal Nehru (1947–1964), and the most recent being Manmohan Singh (2004–2014). Since the 1990s, the Bharatiya Janata Party has emerged as the main rival of the Congress in both national and regional politics.
