Chief Minister of Assam

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.
