Political career.
Chamling was elected as the president of Yangang Gram Panchayat in 1982. In 1985, he was elected to the Sikkim Legislative Assembly for the first time. After being elected for the second time from Damthang, he became the Minister for Industries, Information and Public Relations from 1989 to 1992 in the Nar Bahadur Bhandari cabinet. After a series of major political upheavals in Sikkim, Chamling formed the Sikkim Democratic Front on 4 March 1993.
Chamling is the second chief minister in India after Jyoti Basu, of West Bengal to govern a state five terms in a row, with his party Sikkim Democratic Front winning the 1994, 1999, 2004, 2009 and 2014 Sikkim Legislative Assembly elections. His party first came to power in Sikkim after winning the 1994 Sikkim assembly elections. His popularity kept soaring in Sikkim due to his developmental work and for maintaining peace. In 2009, his party Sikkim Democratic Front won all 32 assembly seats in Sikkim Legislative Assembly.
In 2012, he faced allegations of corruption and Bhandari, his predecessor as CM, predicted that Chamling would go to jail if he lost his power. And his former comrade Tamang (Golay) developed differences with him and floated his own party. These developments created political challenge for him, but he managed to win the assembly elections of 2014, albeit with a much reduced majority. 
Following win in 2014 assembly election, he was sworn in as the Chief Minister of Sikkim for the fifth consecutive time on 21 May 2014 by Shriniwas Dadasaheb Patil, the Governor of Sikkim. He became the chief minister for a fifth time, a record previously held by Jyoti Basu who ruled West Bengal from 1977 to 2000.
His party SDF won 22 out of 32 assembly seats in the 2014 legislative assembly election. 18 months after the 2014 elections, on 30 November 2015, 7 out of 10 opposition MLAs joined the SDF party under the leadership of Pawan Chamling. The ruling front had 29 out of 32 assembly seats in the state.
On 18 January 2016 Prime Minister of India Narendra Modi made a two-day visit to the state to declare Sikkim as the first and the only "organic state" in the country, as it has fully implemented organic farming statewide.
Chamling resigned as CM after 2019 Sikkim Legislative Assembly election as former member Prem Singh Tamang's Sikkim Krantikari Morcha party formed the government by winning 17 seats out of 32. SDF party won the remaining 15 seats. But in August 2019, 10 MLAs quit his party to join Bharatiya Janata Party and in the same month two other legislators joined Sikkim Krantikari Morcha. Thus making Chamling only MLA of from the party.
