On April 1, 1936, Bihar and Odisha (former Orissa) emerged as separate provinces following the partition of Bihar and Orissa. Under the Government of India Act 1935, a bicameral legislature was introduced, comprising a legislative assembly and a legislative council, with a Premier leading the government. This marked a significant chapter in the political evolution of Bihar.

President"s rule in Bihar
President`s rule, a constitutional provision invoked in exceptional circumstances, has been imposed in Bihar multiple times, each instance reflecting a distinct set of challenges. From June 29, 1968, to February 26, 1969, Bihar experienced a period of direct governance by the President. Subsequently, President`s rule was again imposed from July 6, 1969, to February 16, 1970, followed by another episode from January 9, 1972, to March 19, 1972. The state witnessed further instances of central intervention during April 30, 1977, to June 24, 1977, and then from February 17, 1980, to June 8, 1980. In more recent times, President`s rule was declared from March 28, 1995, to April 4, 1995, and then from February 11, 1999, to March 9, 1999. The most recent instances occurred during March 7, 2005, to November 24, 2005. These periods of central administration signify times of political uncertainty and governance challenges in Bihar, where the central government took charge to restore stability and order.
