Munda began his political career in his teens during early 1980s when he joined the Jharkhand movement spearheaded by
Jharkhand Mukti Morcha (JMM) which sought to create a separate state for
tribals from the southern regions of
Bihar. A believer in the welfare of indigenous people of his region, Munda felt passionate about the issue and took an active part in the movement. Soon his political influence grew due to his inclusive philosophy and he was elected to the
Bihar Legislative Assembly from
Kharsawan constituency in 1995 on a JMM ticket. The
National Democratic Alliance (NDA) strongly espoused the cause of Jharkhand and ran on a promise to create the state. Munda was attracted to the aspects of selfless nation building and sacrifice in the ideology of the Bharatiya Janata Party (BJP). He believed in its policy of championing the cause of Jharkhand and joined the BJP. He was elected again to the
Bihar Assembly in 2000 elections on a BJP ticket from his old constituency of
Kharsawan. After Jharkhand's formation, he was elected to the
Jharkhand Assembly from the same constituency in 2005 and again in the 2011 by-election after assuming responsibility as the Chief Minister in September 2010. When the NDA government came to power in 1999 under the leadership of
Atal Bihari Vajpayee, it kept its promise and created Jharkhand along with
Uttarakhand and
Chhattisgarh. Munda became the Tribal Welfare Minister in the 1st
Babulal Marandi-led NDA coalition government of Jharkhand, which was carved out from Bihar on 15 November 2000. As welfare minister, he crafted many policies and programs to ameliorate a lot of the poor and downtrodden.
