Mohamed Ibrahim Nugud attended Sofia University in Bulgaria after his dismissal from the University of Khartoum for political activities, graduating with a degree in economics and philosophy. He was elected to the Sudanese Parliament twice during the country's brief periods of democratic rule, in 1965 and in 1986. In 1989, a military coup led to the parliament being dissolved, and Nugud was detained and put under house arrest. He nonetheless managed to disappear until 2005, when he emerged to lead the communist party until his death in 2012. His book on slavery relations in the Sudan is one of six that he published in Arabic.
