Sudan. Sudan lost three-quarters of its oil when South Sudan won independence in 2011. As the oil rents withered, the main substitute revenue came from gold mining, which brought in far less money than oil. The decline forced the longtime ruler, President Omar al-Bashir, to cut subsidies for food and commodities that the population had come to expect. Political also switched away from Bashir, who had largely controlled the oil rents, in favor of militias that controlled the gold mines, far from Khartoum. These changes left Bashir particularly vulnerable to dissent — from the top and the bottom — and contributed to his overthrow in 2019.
