The Congress Party is the common name for the Indian National Congress. It is one of the world's oldest political parties. It was established in 1885. After independence, it played a significant role in Indian politics at national and state levels. Under Nehru's leadership, the party attempted to establish a contemporary secular democratic republic in India. It ruled until 1977, again from 1980 to 1989, although its popularity declined eventually. The party is pro-secularism and aims to welfare marginalized groups and minorities. It is a humane supporter of new economic changes. In the 2004 elections, it emerged as the single largest party with 145 seats, and it now serves as the center's opposition.
