The M23 rebellion was an armed conflict in North Kivu, Democratic Republic of the Congo, that occurred between the March 23 Movement (M23) rebel group and Congolese government forces between 4 April 2012 and 7 November 2013. It ended when a peace agreement was made among eleven African nations, and the M23 troops surrendered in Uganda. The rebellion was part of continued fighting in the region after the formal end of the Second Congo War in 2003. The conflict reignited in late 2021 after M23 rebel leader Sultani Makenga and 100 rebel fighters attacked the border town of Bunagana but failed. A few months later, M23 rebels officially restarted offensive operations, rapidly expanding their control over vast regions of North Kivu.
