Kintu created the kingdom of Buganda by forcefully taking over the five clans that lived in the region. To signify his victory over a clan, he would sleep in the conquered leader's home; tradition says that Buganda was the name of the first house that he slept in after his victory over Bemba and his tribe. Buganda was later used to refer to the entire area he subdued.
Kintu Kato is not to be confused with Kintu, the first person on the earth according to Buganda legend. Kato Kintu gave himself the name Kintu, a name that he knew the Baganda associated with the father of all people.
