In the early 1920s, between 5-15,000 pilgrims were coming to Aba Island each year to celebrate Ramadan. Many of them identified Abd al-Rahman with the prophet Jesus and assumed that he would drive the white Christian colonists out of Sudan. The British government found that Abd al-Rahman was in correspondence with agents and leaders in Nigeria and Cameroon, predicting the eventual victory of the Mahdists over the Christians. They blamed him for unrest in these colonies. After pilgrims from West Africa held mass demonstrations on Aba Island in 1924, the Sayyid was told to put a stop to the pilgrimages.
