Samrat Choudhary, who was Bihar's deputy chief minister until yesterday, became the first BJP leader to hold the top position in the state when he took the oath of office on Wednesday. Samrat Chaudhary was sworn in at Lok Bhavan in Patna by Bihar Governor Syed Ata Hasnain.
With the noteworthy exception of Bihar, the BJP has chief ministers in all of the main Hindi heartland states, including Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Rajasthan, Uttarakhand, Haryana, and Delhi. With Samrat Choudhary of the BJP being promoted to the highest position in the state today, that was formally altered.
Nitish Kumar, who is currently a member of the Rajya Sabha, resigned as chief minister on Tuesday.

"The task in Bihar will now be handled by the new government. The longest-serving chief minister of Bihar, Kumar, wrote on X, "The new government will have my full cooperation and guidance."
With his promotion, Nitish Kumar's "Sushasan (good governance)" came to an end and a new chapter for the NDA in Bihar began.
The Koeri, or Kushwaha caste, is a well-known other backward class (OBC) group that makes up about 6-7% of Bihar's population. Choudhary, 57, was Nitish Kumar's deputy.

After the Yadavs, the Kushwaha community is the biggest among the backward castes. Sources claim that the BJP was asked by Nitish Kumar's JD(U) to name a chief minister from this particular caste.
Samrat Choudhary was born in 1968 into a politically active family. Shakuni Choudhary, his father, represented the Tarapur constituency as an MLA six times. For the now-defunct Samta Party, his mother, Parvati Devi, won the same seat in 1998.
Since entering politics in 1990, Choudhary has made numerous party switches, joining the BJP in 2017 after first joining Lalu Yadav's RJD and then Nitish's JDU.
