Nitish Kumar has maintained a prominent position in Bihar politics, holding the office of Chief Minister multiple times since 2000. His political journey has been characterized by strategic alliance formations and dissolutions, positioning him as a central figure in the state's governance for over two decades. By August 2022, Mr. Kumar had been sworn in as Bihar's Chief Minister for the eighth time, a testament to his enduring presence and influence in the state's political landscape.

Mr. Kumar's political trajectory began with his initial brief stint as Chief Minister in March 2000. Following the 2005 state assembly elections, he assumed the role again, leading the Janata Dal (United) (JD(U)) in alliance with the Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA). This period saw a focus on governance, infrastructure development, and improvements in law and order, which contributed to his public image. His leadership has frequently been cited by observers as a key factor in navigating Bihar's complex political dynamics.

A significant shift occurred in 2013 when Mr. Kumar broke ties with the NDA, citing disagreements over the BJP's leadership. He subsequently allied with the Rashtriya Janata Dal (RJD) and the Congress party to form the Mahagathbandhan (Grand Alliance) in 2015, returning as Chief Minister. However, this alliance proved temporary. In July 2017, citing issues including corruption allegations against alliance partners, Mr. Kumar resigned and swiftly rejoined the NDA, once again forming a government with the BJP. This move demonstrated his readiness to realign political forces to retain power.

The most recent significant shift, as of August 2022, saw Mr. Kumar once again severing ties with the BJP-led NDA. He then moved to form a new Mahagathbandhan government, bringing together the JD(U) with the RJD, Congress, and Left parties. This change led to his eighth swearing-in as Chief Minister on August 10, 2022. These repeated changes in alliance underscored his consistent objective of maintaining his leadership role in the state's administration.

Key political milestones in Nitish Kumar's Chief Ministerial tenures include:

  • March 2000: First brief term as Chief Minister.
  • November 2005: Sworn in as CM, leading the NDA government.
  • November 2010: Re-elected as CM, continuing the NDA alliance.
  • May 2014: Resigned after the JD(U)'s poor performance in general elections, but returned as CM in February 2015 after Jitan Ram Manjhi's brief tenure.
  • November 2015: Sworn in as CM of the Mahagathbandhan government (JD(U), RJD, Congress).
  • July 2017: Resigned from Mahagathbandhan, then immediately rejoined NDA and was sworn in as CM.
  • November 2020: Sworn in as CM after the state assembly elections, continuing the NDA alliance.
  • August 2022: Sworn in as CM for the eighth time, forming a new Mahagathbandhan government.

Mr. Kumar's repeated transitions between major political blocs have cemented his image as a pragmatic leader capable of navigating complex coalition politics. His actions have consistently resulted in him retaining the Chief Ministerial position, highlighting his strategic approach to state governance and alliance management. The long-term implications of such frequent political realignments for Bihar's development and political stability remain a subject of ongoing observation among political analysts.
