The Hororo or Bahororo are a small nomadic Bantu tribe living in the north of the Kigezi District of Uganda. In 1905, they were described by a British officer as a "quiet, inoffensive people" who did not own cattle. They are made up mostly of the Hima (historically the land owners as one could only own land if they had cows). The Bahororo are more associated with Kigezi than Ankole. They reside mainly in Rujumbura in south western Uganda and are related to the Tutsi of Rwanda most Bahororo can trace their roots to the Buyumba region. The Bahororo speak a dialect of Nkore-Kiga, Ruhororo, and are subdivided into clans most of which are common to both the Nkole and Kiga nations.
The Bahororo trace their roots back to the kingdom of Cush in modern-day Ethiopia. However human and cattle genetics indicate that Bahima and Batutsi probably originate in the Central Sahara area.
Rise of the Hororo State
Prior to the mid-1700s, the area that became Mpororo - land of the Hororo - was known as Ndorwa, and constituted the southern province of the kingdom of Busongora. During the reign of Queen Kitami cya Nyawera of Busongora a fugitive Rwandan prince named Murari Kamali arrived at the court of the queen and was granted asylum. Murari was a claimant to the Rwandan throne but he and his supporters were ousted by his brother Kigeri II Nyamuheshera. At that time Rwanda and Busongora shared a common border, and Murari and his people escaped and crossed into Busongora.
Murari entered Busongora and was led to the palace of Queen Kitami. The Songora queen is remembered mostly for the fact that she was greatly feared, she was exceptionally attractive, and most importantly, her most elite military units consisted entirely of female warriors. Murari stayed at Kitami's royal court and she decided to marry the Rwandan prince. Together they had a son and they named him Kahaya Rutindangyezi. The king Kigeri II of Rwanda to the south decided to invade Busongora in pursuit of Murari. The commander of the Rwandan troops was called Bihira-bya-Muhuruzi. Biriha was a member of the AbaKono sub-clan of the AbEga clan.
