On 25 October 2021, the Sudanese military, led by General Abdel Fattah al-Burhan, took control of the Government of Sudan in a military coup. At least five senior government figures were initially detained. Civilian Prime Minister Abdalla Hamdok refused to declare support for the coup and on 25 October called for popular resistance; he was confined to house arrest on 26 October. Internet outages were reported. Later the same day, the Sovereignty Council was dissolved, a state of emergency was put in place, and a majority of the Hamdok Cabinet and a number of pro-government supporters were arrested. As of 5 November 2021, the list of those detained included "government ministers, members of political parties, lawyers, civil society activists, journalists, human rights defenders, and protest leaders", who were held in secret locations, without access to their families or lawyers.

The Transitional Sovereignty Council is the collective head of state of Sudan, formed on 20 August 2019, by the August 2019 Draft Constitutional Declaration. It was dissolved by Chairman Abdel Fattah al-Burhan in the October 2021 Sudanese coup d'état and reconstituted the following month with new membership, effectively changing it from a unity government to a military junta.
