Sudan has had a military dictatorship from 1989-2019 (led by Omar al-Bashir).
In 2017, both President Obama and President Trump lifted sanctions on Sudan, after al-Bashir reneged on a promise to step down just two years earlier.
In 2018/2019, price hikes resulted in massive protests and a subsequent revolution against al-Bashir. This finally resolved in 2019, when a joint military-civilian political agreement, constitution, and council were formed. At that point, lots of aid was needed in order to rebuild and stabilize the country, but as usual, actually getting that money was difficult. The bulk of it came from Saudi Arabia and the UAE.
In 2021, there were two more coups.
In 2023, a new civil war broke out between the military dictatorship and a paramilitary branch of it. That war is still persisting. War crimes are rampant, mass-murder and genocide persist, almost the entire country cannot afford food. The main backer of the paramilitary group preventing the conflict from ending is the UAE.
