The prime minister of India is the chief executive of the Government of India. Although the President of India is the constitutional, nominal, and ceremonial head of state, in practice and ordinarily, the executive authority is vested in the Prime Minister and their chosen Council of Ministers. The prime minister is the leader elected by the party with a majority in the lower house of the Indian parliament, the Lok Sabha, which is the main legislative body in the Republic of India. The prime minister and their cabinet are at all times responsible to the Lok Sabha. The prime minister can be a member of the Lok Sabha or of the Rajya Sabha, the upper house of the parliament. The prime minister ranks third in the order of precedence. The prime minister is appointed by the president of India; however, the prime minister has to enjoy the confidence of the majority of Lok Sabha members, who are directly elected every five years, unless a prime minister resigns. The prime minister is the presiding member of the Council of Ministers of the Union government. The prime minister unilaterally controls the selection and dismissal of members of the Council; and allocation of posts to members within the government. This Council, which is collectively responsible to the Lok Sabha as per Article 75(3), assists the president regarding the operations under the latter's powers; however, by the virtue of Article 74 of the Constitution, such 'aid and advice' tendered by the Council is binding.

Jawaharlal Nehru was India's first prime minister, serving as prime minister of the Dominion of India from 15 August 1947 until 26 January 1950, and thereafter of the Republic of India until his death in May 1964. (India conducted its first post-independence general elections in 1952). Earlier, Nehru had served as prime minister of the Interim Government of India during the British Raj from 2 September 1946 until 14 August 1947, his party, the Indian National Congress having won the 1946 Indian provincial elections.) Nehru was succeeded by Lal Bahadur Shastri, whose 1 year 7-month term ended in his death in Tashkent, then in the USSR, where he had signed the Tashkent Declaration between India and Pakistan. Indira Gandhi, Nehru's daughter, succeeded Shastri in 1966 to become the country's first female prime minister. Eleven years later, her party the Indian National Congress
