On May 25, 1969, Colonel Gaafar Nimeiry and a group of leftist military officers overthrew Sudan's parliamentary government in a nearly bloodless coup, establishing the Revolutionary Command Council. Nimeiry would rule Sudan for the next sixteen years, steering it through shifting alliances between socialism, Arab nationalism, and later Islamist governance.
Sudan's fragile parliamentary democracy, reinstated only three years earlier after a previous military regime, had grown paralyzed by factional infighting among dozens of small parties, unable to address the country's grinding civil war in the south or its economic stagnation. Nimeiry, a 39-year-old colonel with ties to Egypt's Gamal Abdel Nasser, moved troops into Khartoum before dawn and seized the radio station, government buildings, and key ministers with minimal resistance.
He initially aligned his Revolutionary Command Council with communists and Arab nationalists, nationalizing banks and foreign businesses, before violently purging the Sudanese Communist Party after a failed 1971 counter-coup attempt against him. His politics zigzagged dramatically over the following years, from socialism to a peace deal ending the first Sudanese civil war in 1972, to an alliance with the United States, and finally to the imposition of strict Islamic sharia law in 1983.
That last reversal reignited civil war in the south and eroded his domestic support, and Nimeiry was himself overthrown in a 1985 coup while out of the country visiting the United States. His sixteen-year rule left Sudan more fractured than he'd found it, setting patterns of military intervention that would recur throughout the country's later history.
