Sudan has a troubled history and has been in almost constant turmoil since the 1950s. Regime change, coups, street protests, famine, war, political division - and in April 2019, the toppling of President Omar al-Bashir. The history of modern Sudan is punctuated by several coups, including in 1989, the seizing of power by al-Bashir, whose regime would last for three decades. In the background was Hassan al-Turabi, the power behind the leadership, and the man many call the architect of modern Sudan. In this two-part series, we trace the rise and fall of Hassan al-Turabi, and explore the vast influence he had over five decades of Sudanese politics.
