After he completed his term in the 1970s, Kamaraj became the leader of the Bahujan Samaj, a Dalit party that fought for the rights of the socially and economically oppressed. The party contested the 1971 general elections in the name of B.R. Ambedkar and P. A. Deshmukh. The Bahujan Samaj Party (BSP) won 22 seats in the 1971 Lok Sabha election and 1 in the 1975 Lok Sabha election. In the 1977 general election the party formed an alliance with the Congress, which led to the Congress being voted out. The BSP joined the Janata Party but remained outside the Congress-led alliance. In the 1980 general election, the BSP won 11 seats and in December 1983, the BSP signed a pact with the Congress and the Janata Party, which led to the formation of a new government, the Janata Party II. Kamaraj's son Dr.B. Sriram was elected as an MP in the Lok Sabha in 1991 and 1996. The BSP was re-organised with Congress support in 2009, forming a coalition with the Congress.
In 2013 he was appointed the Chairman of the National Advisory Council. Kamaraj, who was awarded the Bharat Ratna in 1975, was said to be someone whose contribution spanned the entire spectrum of public participation and leadership. Some of his attributes as a political leader are:
During the Emergency (1975-77), the Supreme Court commented that Kamaraj had the distinction of being one of the most active and successful leaders of the Opposition. Even when the Emergency was imposed and the Government clamped down on the opposition, Kamaraj consistently opposed the Government and persistently sought to empower the Opposition.
Kamaraj's principal assignment was the role of a National Leader. He never had any illusions about the role and status of a political leader. He insisted that the job of a political leader is not to take political power into his or her hands but to inspire and drive the masses to take action to bring about social change. 7211a4ac4a
