Chief Minister of Assam

The chief minister of Assam, an Indian state, is the head of the government of Assam. As per the Constitution of India, the governor is the state's de jure head, but de facto executive authority rests with the chief minister. Following elections to the Assam Legislative Assembly, the governor usually invites the party (or coalition) with a majority of seats to form the government. The governor appoints the chief minister, whose council of ministers are collectively responsible to the assembly. Given that he has the confidence of the assembly, the chief minister's term is for five years and is subject to no term limits.^[1]

Since 1946, Assam has had 17 chief ministers. Ten of them belonged to the Indian National Congress, including Gopinath Bordoloi, the first chief minister of Assam, and Anwara Taimur, India's first female Muslim chief minister. Congress party's continuous rule in the state was brought to an end when Golap Borbora led the Janata party to victory in the 1978 elections. Borbora consequently became the first non-Congress chief minister of the state. Prior to that, Borbora was also the first non-Congress leader to be elected to the Rajya Sabha from the state. Congressman Tarun Gogoi is the longest-serving officeholder, having served for 15 years between 2001 and 2016. Sarbananda Sonowal became the first chief minister from the Bharatiya Janata Party, when he was sworn in on 24 May 2016. On 9 May 2021, Himanta Biswa Sarma was announced as the 15th chief minister of Assam.^[2]

Notes

1. A parenthetical number indicates that the incumbent has previously held office.
2. This column only names the chief minister's party. The state government he heads may be a complex coalition of several parties and independents; these are not listed here.
3. When President's rule is in force in a state, its council of ministers stands dissolved. The office of chief minister thus lies vacant. At times, the legislative assembly also stands dissolved.^[4]
