Three past Kyabazingas have presided over the federated state of Busoga since 1939: Ezekiel Tenywa Wako, Yosia Nadiope and William Wilberforce Nadiope Kadhumbula.
Kadhumbula played an important role in Uganda's independence struggle; he was also the first vice-president of independent Uganda and chairman of the Uganda People's Congress (UPC).
