From the Document: "On April 11, 2019, Sudan's military removed President Omar al Bashir from office after three decades in power. Four months of near-daily protests across the country had shaken the government, and in early April, huge crowds gathered in front of the military's headquarters in Khartoum to demand regime change. The protests, triggered by austerity measures amid an economic crisis, were fueled by a range of grievances against the ruling National Congress Party (NCP) and Bashir, who took power in a 1989 coup. [...] U.S. relations with Sudan have been turbulent for three decades. The United States restricted aid after the 1989 coup, and in subsequent years imposed a range of sanctions through Executive Orders and congressional measures. Restrictions on U.S. engagement are based on Sudan's debt arrears, links to international terrorism, and pervasive human rights violations. The State Department has designated Sudan as a Country of Particular Concern under the International Religious Freedom Act."
