Bihar Government Formation 2025 | Nitish Kumar among top 10 longest-serving chief ministers

Patna: No chief minister in the country would have taken oath as many times as Bihar’s longest-serving CM Nitish Kumar, who was sworn in for a record 10th term on Thursday.

At 74, Kumar also achieved another milestone of extending his 19-year stint as CM and breaking into the national top-10 list of longest-serving heads of government.

Kumar assumed office as chief minister in a grand swearing-in ceremony at Patna's Gandhi Maidan in the presence of Prime Minister Narendra Modi and Home Minister Amit Shah, besides several top NDA leaders.

Born in 1951 in Bihar's Bakhtiyarpur, Kumar entered politics during the JP Movement. He joined the Janata Party and unsuccessfully contested his first assembly elections in 1977. His first electoral victory was in 1985.

His frequent switching of sides in his nearly five-decade-long political career earned him the nickname 'Paltu Ram', whereas he is also called 'Sushashan Babu' for his good governance.

As the country's political landscape turns another page, Kumar joins the ranks of the nation’s 10 longest-serving CMs, a list dominated for decades by stalwarts such as Pawan Kumar Chamling of Sikkim and Naveen Patnaik of Odisha.
