Omar Hassan Ahmad al-Bashir (; born 1944) is the former President of Sudan. He came into power in 1989 and resigned in 2019 following massive anti-protests and a coup. In October 2004, Omar's government negotiated an end to the second Sudanese civil war, one of the longest-running and deadliest wars of the 20th century. However, there has been a violent conflict in Darfur that has resulted in a death toll between 200,000 and 400,000. During his presidency, there have been several violent struggles between the rebel groups such as the Sudanese Liberation Army (SLA) and the Justice and Equality Movement (JEM) in the form of warfare in the Darfur region. The civil war has resulted in over 2.5 million people being displaced, and the relations between Sudan and Chad are at a crisis.
