Isingoma Mpuga Rukidi was the great grandchild of Isaza Nyakikooto, the last Batembuzi King.
When Omukama Isaza was subdued by Nyamiyonga(chwezi) to the underworld with her beautiful daughter nyamata(milky), the encounter lead to the birth of Isimbwa
Isimbwa grew up in the underworld and Nyamigonga had given him one of his women called Nyabiryo, the encounter lead to the birth of Kyomya.
Isimbwa also used to visit earth from the underworld, and he had an encounter with Nyinamwiru, the daughter of Bakuku(Caretaker of King Isaza throne), and their encounter lead to the birth of Ndahura Kyarubumbi who become the first bachwezi king after killing Bakuku.
When the bachwezi took power, Kyomya was freed from the underworld and married Nyatworo, daughter of Labongo, a man from Bukidi(Lango) of the Jo-bito clan and the couple gave birth to nine children and among the nine were twins, Isingoma Rukidi Mpuga and Kato Kimera.
Omukama Wamara, son to Ndahura and was the reigning King of the Bachwezi during the times Rukidi was born, he was facing many challenges from the different disgruntled princes, and people had soon discovered that their powers were no longer invincible and the death of a loved cow called Bihogo had revealed an end to their rule.
So Omukama wamara decided to abdicate the throne, whilst he consulted his counselors and decided to send messengers, one of whom was Nyakoko, to fetch one of his uncle Kyomya’s twins who would succeed him
According to legend the elder twin Isingoma Mpuga Rukidi was chosen. He longed to possess and to rule the land described to him but he feared to do so because he was ignorant and savage. Nyakoko saw a chance to advance his own interests by guiding Isingoma Mpuga Rukidi to Kitara and by initiating him into the customs of the country himself. So the Babito prepared for their journey.
Nyakoko warned Isingoma Mpuga Rukidi that the country was full of falsehood and treachery that the women were faithless and unchaste, and he asked Isingoma Mpuga Rukidi whom the Babito would marry. Isingoma Mpuga Rukidi replied that if this was so, they would marry their own women folk.
Isingoma Mpuga Rukidi took the totem of his mother, engabi-bushbuck, and as a result the Babito have this totem today. Isingoma means the elder of twins, literally ‘the father of the drum’. Mpuga means patchy,because he had patches on his skin and this is thought to indicate his descent from the Bachwezi. Rukidi means the naked one, because he came from Bukidi, the land of nakedness.
