Shaba I was a conflict in Zaire's Shaba (Katanga) Province lasting from March 8 to May 26, 1977. The conflict began when the Front for the National Liberation of the Congo (FNLC), a group of about 2,000 Katangan Congolese soldiers who were veterans of the Congo Crisis, the Angolan War of Independence, and the Angolan Civil War, crossed the border into Shaba from Angola. The FNLC made quick progress through the region because of the sympathizing locals and the disorganization of the Zairian military (Forces Armées Zaïroises, or FAZ). Travelling east from Zaire's border with Angola, the rebels reached Mutshatsha, a small town near the key mining town of Kolwezi.
