India is a federal state, which includes 29 states established on essentially linguistic bases, and seven union territories created for political or historical reasons (Delhi, Pondicherry). It is a parliamentary democracy, inspired by the British model. Its constitution of January 26, 1950 proclaims the socialist and secular character of the State. Parliament has two Houses: the States House (Rajya Sabha, upper house) and the People's House (Lok Sabha, lower house). The leader of the majority party in the Lok Sabha is appointed Prime Minister. The President of the Republic has an essentially symbolic role.

It dominated the Indian political scene at the time of independence and until the 1990s. The Bharatiya Janata Party (BJP), founded in 1980, represents the conservative Hindu right. He won the legislative elections in 1998, 2014 and 2019.

However, the 2019 election seems to have reshuffled the cards, and the BJP has made historic inroads in the northeast of the country and in the state of West Bengal, in particular.
At the end of the legislative elections which took place from April 11 to May 19, 2019 in which nearly 900 million people were called to vote, the BJP candidate, Narendra Modi, was elected Prime Minister. The BJP alone has a large majority in the Lower House, with 303 seats out of 545, the threshold being 272 elected officials. This majority is further supported by the results of regional parties won by the BJP, all forming a coalition of 353 seats, the National Democratic Alliance. The ruling BJP, however, does not have a majority in the upper house of parliament, whose members are elected by the local assemblies of the federated states.
Since coming to power, the BJP has won the majority of intermediary elections held in regional parliaments. The resounding success of the BJP in March 2017 in Uttar Pradesh,
