Soukous (also known as Lingala or Congo, an previously as African rumba) is a musical genre that originated in the two neighbouring countries of Belgian Congo and French Congo during the 1930s and early 1940s, and which has gained popularity throughout Africa. "Soukous" (said to be a derivative of the French word secouer, to shake) was originally the name of a dance popular in the Congos in the late 1960s, and danced to an African version of rumba. Although the genre was initially known as rumba (sometimes termed specifically as African rumba), the term "soukous" has come to refer to African rumba and its subsequent developments.
