Bharatiya Janata Party

The party's origins lie in the Bharatiya Jana Sangh, which was founded in 1951 by Indian politician Syama Prasad Mukherjee, after he left Hindu Mahasabha to form a party as the political wing of RSS.[50][51] After the Emergency of 1975–1977, the Jana Sangh merged with several other political parties to form the Janata Party; it defeated the then-incumbent Indian National Congress in the 1977 general election. After three years in power, the Janata Party dissolved in 1980, with the members of the erstwhile Jana Sangh reconvening to form the modern-day BJP. Although initially unsuccessful—winning only two seats in the 1984 general election, it grew in strength on the back of the movement around Ram Janmabhoomi in Uttar Pradesh. Following victories in several state elections and better performances in national elections, the BJP became the largest political party in the Parliament in 1996; however, it lacked a majority in the lower house of Parliament, and its government, under its then-leader Atal Bihari Vajpayee, lasted for only 13 days.
