The Bharatiya Jana Sangh was formed in 1951 with Shyama Prasad Mukherjee as its founder- President. Its lineage however can be traced back to the Rashtriya Swayamsevak Sangh (RSS) and the Hindu Mahasabha before Independence.The Jana Sangh was different from other parties in terms of ideology and programmes. It emphasized the idea of one country, one culture and one nation and believed that the country could become modern, progressive and strong on the basis of Indian culture and traditions. The party called for a reunion of India and Pakistan in Akhand Bharat. The party was in forefront of the agitation to replace English with Hindi as the official language of India and was also opposed to the granting of concessions to religious and cultural minorities. The party was a consistent advocate of India developing nuclear weapons especially after China carried out its atomic tests in 1964
