The Bharatiya Janata Party is one of the two major parties in the Indian political system, along with the Indian National Congress. As of 2015, it is the country's largest political party in terms of representation in the national parliament and state assemblies, and it is the world's largest party in terms of primary membership. The BJP is a right-wing party,with close ideological and organisational links to the Hindu nationalist Rashtriya Swayamsevak Sangh. The BJP's origins lie in the Bharatiya Jana Sangh, formed in 1951 by Syama Prasad Mookerjee. 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. After three years in power, the Janata party dissolved in 1980 with the members of the erstwhile Jana Sangh reconvening to form the BJP. Although initially unsuccessful, winning only two seats in the 1984 general election, it grew in strength on the back of the Ram Janmabhoomi movement. Following victories in several state elections and better performances in national elections, the BJP became the largest party in the parliament in 1996; however, it lacked a majority in the lower house of Parliament, and its government lasted only 13 days. After the 1998 general election, the BJP-led coalition known as the National Democratic Alliance (NDA) formed a government under Prime Minister Atal Bihari Vajpayee for a year. Following fresh elections, the NDA government, again headed by Vajpayee, lasted for a full term in office; this was the first non-Congress government to do so. In the 2004 general election, the NDA suffered an unexpected defeat, and for the next ten years the BJP was the principal opposition party. Long time Gujarat Chief Minister Narendra Modi led it to a landslide victory in the 2014 general election. Since that election, Modi leads the NDA government as Prime Minister and as of March 2015, the alliance governs 13 states. The official ideology of the BJP is "integral humanism", first formulated by Deendayal Upadhyaya in 1965. The party expresses a commitment to Hindutva, and its policy has historically reflected Hindu nationalist positions. The BJP advocates social conservatism and a foreign policy centred on nationalist principles. Its key issues have included the abrogation of the special status to Jammu and Kashmir, the building of a Ram temple in Ayodhya and the implementation of a uniform civil code. However, the 1998–2004 NDA government did not pursue any of these controversial issues. It instead focused on a largely neoliberal economic policy prioritizing globalisation and economic growth over social welfare. As of April 2015, the BJP holds a majority of assembly in eight states: Gujarat, Madhya Pradesh, Chhattisgarh, Rajasthan, Goa, Haryana, Maharashtra and Jharkhand. In four other states and one union territory – Jammu & Kashmir, Punjab, Nagaland, Andhra Pradesh, and Puducherry, respectively – it shares power with other political parties of the NDA coalition. The BJP has also been the sole party in power in Uttar Pradesh, Arunachal Pradesh, Uttarakhand, Himachal Pradesh, Karnataka, and Delhi. It has also ruled Odisha and Bihar as part of coalition governments. The BJP is the world's largest political party by primary membership, having 100 million registered members as of April 2015. The organisation of the BJP is strictly hierarchical, with the president being the highest authority in the party.Until 2012, the BJP constitution mandated that any qualified member could be national or state president for a single three-year term. This was amended to a maximum of two consecutive terms.Below the president is the national executive, which contains a variable number of senior leaders from across the country. It is the higher decision making body of the party. Its members are several vice-presidents, general-secretaries, treasurers and secretaries, who work directly with the president.An identical structure, with an executive committee led by a president, exists at the state, regional, district and local level. The BJP is a cadre-based party. It has close connections with other organisations with similar ideology, such as the Rashtriya Swayamsevak Sangh and the Vishwa Hindu Parishad. The cadres of these groups often supplement the BJP's. Its lower members are largely derived from the RSS and its affiliates, loosely known as the Sangh Parivar: The Akhil Bharatiya Vidyarthi Parishad (All India Student's Union), the students' wing of the RSS. The Bharatiya Kisan Sangh (Indian Farmer's Union), the farmers' division. The Bharatiya Mazdoor Sangh (Indian Labourers Union), the labour union associated with the RSS. The party has subsidiary organisations of its own, such as: The BJP Mahila Morcha (BJP Women's Front), its women's division. The Bharatiya Janata Yuva Morcha (Indian People's Youth Front), its youth wing. The BJP Minority Morcha (BJP Minority Front), its minority division.
