BJP leader Samrat Choudhary was sworn in as the chief minister of Bihar on Wednesday, the first from the saffron party to hold the post.
Governor Lt Gen Syed Ata Hasnain (retd) administered the oath of office and secrecy to Choudhry.
Top leaders of the ruling NDA in Bihar, which comprises the BJP,
JD(U) and three other parties, attended the ceremony. They included Union Ministers J P Nadda and Chirag Paswan, Nitish Kumar, and all NDA MLAs.
Nitish Kumar, who is now a Rajya Sabha MP, relinquished the chief minister's post on Tuesday, dissolving his cabinet in which Choudhary was a deputy chief minister and held the crucial home portfolio.
