The Congress Party developed out of the Indian National Congress (founded 1885) and has been the dominant force in Indian politics for most of the period since Independence (1947). The family of the first Prime Minister of India, Jawaharlal Nehru, has in turn dominated the Party, providing further Prime Ministers in Nehru's daughter, Indira Gandhi, and her son Rajiv, both assassinated. After a politically disastrous period in the 1990s, Rajiv's widow, Sonia Gandhi (b. 1946), led Congress back to power in the 2004 elections, although she declined to become Prime Minister herself. In contrast to the Hindu nationalist stance of its recent major rival, the Bhāratīya Janatā Party, Congress has always campaigned on a non-sectarian and secular platform.
