Ahmed al-Mirghani in the context of List of heads of state of Sudan

Omar Hassan Ahmad al-Bashir (born 1 January 1944) is a Sudanese former military officer and politician who served as Sudan's head of state under various titles from 1989 until 2019, when he was deposed in a coup d'état. He was subsequently imprisoned, tried and convicted on multiple corruption charges.

Al-Bashir came to power in 1989 when, as a brigadier general in the Sudanese Army, he led a group of officers in a military coup that ousted the democratically elected government of prime minister Sadiq al-Mahdi after it began negotiations with rebels in the south; he subsequently replaced President Ahmed al-Mirghani as head of state. He was elected three times as president in elections that have been under scrutiny for electoral fraud. In 1998, al-Bashir founded the National Congress Party, which remained the dominant political party in the country until 2019. In March 2009, al-Bashir became the first sitting head of state to be indicted by the International Criminal Court (ICC), for allegedly directing a campaign of mass killing, rape, and pillage against civilians in Darfur. On 11 February 2020, the Government of Sudan announced that it had agreed to hand over al-Bashir to the ICC for trial.

A coup d'état was carried out by the Sudanese Armed Forces on 30 June 1989 against the democratically elected government of Prime Minister Sadiq al-Mahdi and President Ahmed al-Mirghani. The coup was led by military officer Omar al-Bashir who took power in its aftermath; he ruled the country for the next 30 years until he was overthrown in 2019.
