Mwami Mwezi IV Gisabo Bikata-Bijoga (1840 – 1908) was the king of Burundi from 1852 to 1908. He was the son of king Ntare IV Rutaganzwa Rugamba. During his reign Burundi was colonized by Germany. An agreement in 1890 allowed Mwezi to stay as king but recognize German authority. Mwezi also had to face rebellions from two chiefs named Magoonco and Syalima, who were recognized by the Germans in 1903. This recognition was withdrawn in 1905, however, and the rebellions were extinguished by 1906.
