As the results of the Bihar 2025 assembly elections begin to unfold, attention is firmly fixed on Nitish Kumar for obvious reasons- the state’s longest-serving chief minister and one of India’s most seasoned political leaders. Renowned for his political strategy and his skill in adapting to changing alliances, the JD(U) chief continues to stand at the heart of Bihar’s political landscape even after more than two decades in power.
Nitish Kumar entered active political life in 1985 with his first election to the Bihar State Assembly. Four years later, in 1989, he supported Lalu Prasad Yadav in securing the position of Leader of the Opposition, marking his early alignment with mainstream state politics.

Formation of the Samata Party
In 1994, 14 MPs of Janata Dal broke away from the leadership of Lalu Prasad Yadav and rallied behind socialist leader George Fernandes. If Fernandes was the face, Nitish Kumar was the brain behind it. Later, the group came to be known as the Samta Party, marking the beginning of his independent political identity.
Alliance with the BJP and National Politics
In 1996, Nitish Kumar switched allegiance to the BJP. Between 1998 and 2004, he was a member of the NDA government headed by Prime Minister A.B. Vajpayee, holding important portfolios like Railways, Surface Transport, and Agriculture.
