or a coalition of parties with a majority in the Legislative Assembly is appointed as the chief minister by the governor. The Council of Ministers are appointed by the governor on the advice of the chief minister. The Council of Ministers reports to the Legislative Assembly. Tripura sends two representatives to the Lok Sabha (the lower house of the parliament of India) and one representative to the Rajya Sabha (parliament's upper house). In the 2014 Indian general election, both parliament lower house seats were won by the Communist Party of India (Marxist). Panchayats (local self-governments) elected by local body elections are present in many villages for self-governance. Tripura also has a unique tribal self-governance body, the Tripura Tribal Areas Autonomous District Council. This council is responsible for some aspects of local governance in 527 villages with high density of the scheduled tribes. The main political parties are the Bharatiya Janata Party (BJP), the Left Front, the All India Trinamool Congress and Indian National Congress along with regional parties like the IPFT and INPT. Until 1977, the state was governed by the Indian National Congress. The Left Front was in power from 1978 to 1988, and then again from 1993 to 2018. In 1988–93, the Congress and Tripura Upajati Juba Samiti were in a ruling coalition. In the 2013 Tripura Legislative Assembly election, the Left Front won 50 out of 60 seats in the Assembly. The 2018 assembly election resulted in loss for the Left Front; the Bharatiya Janata Party won an overall majority in the state, resulting in the end of the Communist Party's uninterrupted twenty-five year rule. The BJP won 44 out of 60 seats in the Assembly by coalition with the IPFT. The CPI (M) only got 16 seats and Indian National Congress lost by huge margins in all constituencies. Communism in the state had its beginnings in the pre-independence era, inspired by freedom struggle activities in Bengal, and culminating in regional parties with communist leanings. It capitalised on the tribal dissatisfaction with the mainstream rulers, and has been noted for connection with the "sub-national or ethnic searches for identity". Since the 1990s, there has been an ongoing irredentist Tripura rebellion, involving militant outfits such as the National Liberation Front of Tripura and the All Tripura Tiger Force (ATTF); terrorist incidents involving the ATTF claimed a recorded number of 389 victims in the seven-year period from 1993 to
