The Sudanese revolution (Arabic: الثورة السودانية, romanized: al-Thawrah al-Sūdānīyah) was a major shift of political power in Sudan that started with street protests throughout Sudan on 19 December 2018 and continued with sustained civil disobedience for about eight months, during which the 2019 Sudanese coup d'état deposed President Omar al-Bashir on 11 April after thirty years in power. On 3 June, the Khartoum massacre took place under the leadership of the Transitional Military Council (TMC) that replaced al-Bashir, and in July and August 2019 the TMC and the Forces of Freedom and Change alliance (FFC) signed a Political Agreement and a Draft Constitutional Declaration legally defining a planned 39-month phase of transitional state institutions and procedures to return Sudan to a civilian democracy.
In August and September 2019, the TMC formally transferred executive power to a mixed military–civilian collective head of state, the Sovereignty Council of Sudan, and to a civilian prime minister, Abdalla Hamdok and a mostly civilian cabinet, while judicial power was transferred to Nemat Abdullah Khair, Sudan's first female Chief Justice. While it is mainly about this eight-month period, there are debates on the definition of the Sudanese revolution, which may also be interpreted to include the period during the prime ministership of Hamdok, who promised that the transitional period would carry out "the program" of the revolution.
