Question

what are the political reasons due to which BJP-RSS alliance was formed??

Answer 1

The BJP's origin lies in the Bharatiya Jana Sangh, formed in 1951 by Syama Prasad Mukherjee. After the State of Emergency in 1977, the Jana Sangh merged with several other parties to form the Janata Party; it defeated the incumbent Congress party in the 1977 general election.
