On May 25, 1969, several young officers, calling themselves the Free Officers' Movement, seized power. At the conspiracy'ออออs core were nine officers led by Colonel Jaafar an Nimeiri, who had been implicated in plots against the Abbud regime. Nimeiri's coup preempted plots by other groups, most of which involved army factions supported by the SCP, Arab nationalists, or conservative religious groups. He justified the coup on the grounds that civilian politicians had paralyzed the decision-making process, had failed to deal with the country's economic and regional problems, and had left Sudan without a permanent constitution.
