[2][3] While the Governor of Bihar holds the ceremonial role of the constitutional head, real executive authority rests with the chief minister, who is responsible for implementing policies and managing the state’s day-to-day affairs.

In addition to maintaining law and order, the chief minister directs efforts toward economic development, public welfare, and infrastructure improvement.

Administrative oversight is another key function, ensuring government departments and officials deliver public services efficiently and in line with policy objectives.

The Government of India Act 1935 introduced a bicameral legislature in Bihar, with a Legislative Assembly and a Legislatory Council, headed by the Premier.

The role of premier was replaced by the chief minister after India's independence in 1947, with Bihar’s political leadership transitioning to a new democratic framework.
