Bharatiya Jana Sangh is the old name of Bharatiya Janata Party of India. It was started by Dr Syama Prasad Mookerjee (also spelt as Shyama Prasad Mukherjee) on 21st October 1951 at Delhi in consultation with the RSS. The symbol of the party in Indian elections was the lamp. It won three seats in the parliamentary elections in 1952, with Dr Mookerjee as one of the winning candidates.

After the party's bad showing in 1984, it was re-launched as the Bharatiya Janata Party, which was the governing party of India from 1998 until 2004 when the Congress Party won an upset election.
