The Tsotso (Batsotso) are one of the smaller Luhya sub-tribes, settled in the Lurambi area of Kakamega County. Their founding ancestor Mutsotso is said to have led a small group that separated from a larger Luhya migration wave and settled between the Idakho and Wanga territories. Despite their small numbers, the Tsotso maintain distinct clan identities and have contributed significantly to Kakamega town's cultural life.
