إبراهيم عبود
Mahjub was introduced to communist ideas while studying at Fuad I University in Egypt, from which he was expelled in 1948 for political activities. He became Secretary General of the Sudanese Communist Party in February 1949. He was influential in international communist forums. A number of his writings focused on the idea of finding a more Nationalist formula for Marxism in Sudan, rather than the literal application of the experience of the Soviets or the Chinese. These writings helped exacerbate the Soviet-Sino split. He also rejected subordination to the Soviet Communist Party, and in contrast to a large number of other communist parties, supported freedom of religion instead of State atheism. He was arrested by the dictatorship of Ibrahim Abboud in 1959 and his trial speech in his own defence, "By Virtue of Marxism Your Honour", was an assertive and clearly-stated political testament. and under Mahjoub’s leadership, the Communist Party played an important role in overthrowing Abboud in 1964.
