The INC ruled the state from 1956 to 1982. In 1983, the Telugu Desam Party (TDP) won the state elections and N. T. Rama Rao became the Chief Minister of the state for the first time. This broke the long-time single party monopoly enjoyed by the INC. The 1989 elections ended the rule of Rao, with the INC returning to power with Marri Chenna Reddy at the helm. He was replaced by Janardhan Reddy in 1990, who was replaced by Kotla Vijaya Bhaskara Reddy in 1992.
