Idriss Déby
Idriss Déby Itno (18 June 1952 – 20 April 2021) was a Chadian politician and military officer who was the president of Chad from 1990 until his death in 2021 during the Northern Chad offensive. His term of office of more than 30 years makes him Chad's longest-serving president. Déby was a member of the Bidayat clan of the Zaghawa ethnic group. A high-ranking commander of President Hissène Habré's military during the 1980s, Déby played important roles in the Toyota War which led to Chad's victory during the Libyan-Chadian conflict. He was later purged by Habré after being suspected of plotting a coup, and was forced into exile in Libya. He took power by leading a coup d'état against Habré in December 1990. Despite introducing a multi-party system in 1992 after several decades of one-party rule under his predecessors, throughout his presidency, his Patriotic Salvation Movement was the dominant party. Déby won presidential elections in 1996 and 2001, and after term limits were eliminated he won again in 2006, 2011, 2016, and 2021. During the Second Congo War, Déby briefly ordered military intervention on the side of the Congolese government but soon withdrew when his forces were accused of looting
