A centralised administrative structure relied heavily on the king-appointed chiefs of the mitaa. Although these chiefs reported to the king, their positions were shaped by their connections to regional families, which occasionally resulted in political rivalry. The royal family responded by taking action to resolve these conflicts. The chiefs' duties included overseeing corvée labour, managing local tribunals, and collecting local taxes. This arrangement preserved allegiance to the king's central authority while facilitating efficient local control. The following is a list of Kibosho colonial possessions over its 300-year history, along with major chiefdoms (
Mitaa). The communities are grouped between the Rau River to the east and the Weru Weru River to the west. •
Chiefdom of Lyamungo; also known as Lambungu or Lyamungo, is named after its western area near Weru Weru. This name likely reflects its position on a caravan route or its historical connection to the royal Orio clan of Kibosho, which previously lived there before moving to the chiefdom's center in Owoo. When Mangi Horombo began to raid in the late 1700s, it served as a haven for a significant number of immigrants from the Kingdom of Kilema. After staying for a while, they returned home. •
Chiefdom of Narumu; despite being under the Kingdom of Kibosho. The dialects and traditions of the chiefdom are more similar to those of the western Kingdom of Machame. The
pottery produced in the chiefdom is well-known. •
Chiefdom of Umbwe Chini; this chiefdom is where
Nassua and
Shangali sought refuge from Mangi Sina. •
Chiefdom of Kombo; during its time as a colony, Kombo was forced to adopt the customs and language of the Kibosho. Also in the late 1700s, when Mangi Horombo raided, and as a haven for a significant number of immigrants from the Kingdom of Kilema. They spend some time there before going back home. •
Chiefdom of Maro; ancestral home to the ruling Olutu and Malya clans that Mangi Sina almost wiped out as they saw them as rivals in the 1870s. •
Chiefdom of Uchau; The Kulaya clan originates from their first ancestor, Kulaya, who is believed to have descended from the sky at Mkola in mtaa Uchau of Kibosho. Accompanyied by his wife and livestock, Kulaya founded the area's first market, selling grains and vegetables. He was known for a small tail, which his son, Mono-o-Ruwa, did not inherit. Mono-o-Ruwa later befriended the first ancestor of the royal clan. Yansanya also settles here at Nchona from Manushi. •
Chiefdom of Utaruni; home to Mangi Sina, where he moved to Maua during the 1870s. •
Chiefdom of Maua; The Massawe clan initially settled in the chiefdom in the village of Mashe, which has a pond in the Kyumbura River. According to legend, Massawe brought his wife, goats, cattle, yams, bananas, and masale with him, as well as tiny spears devoid of bows or arrows. His descendants eventually relocated to Maua's southern region, close to the Karanga River. •
Chiefdom of Nsinga; home of the Shuo (Shio) clan, who came from the east to settle there. •
Chiefdom of Sungu home of the Chuwa clan, also one of the first places Yansanya settled before moving to Kirima Juu. •
Chiefdom of Uri; As one of the primary settlements of Msele-Kiwoso, who initially came from Ukumi in Kibo, it is regarded as one of the oldest settlements in Kibosho. •
Chiefdom of Mweka ; the oldest chiefdoms in the area. Mweka was governed by a chief from the Tarimo clan, whose first ancestor, Ntesha, is believed to have originated from the east, possibly the Kamba plains. Ntesha gradually traversed the Uru region before settling in Mweka, where he established the ruling house of the clan. •
Chiefdom of Kirima Juu; considered one of the leading chiefdoms of Kibosho, was established by Mangi Kirenga as the population of Kirima Chini increased. •
Chiefdom of Kirima Chini; located south of Kirima Juu, was also one of the leading chiefdoms of Kibosho with its capital, Nchona, where Yansanya lived, bore his children, and died there. Mrenyi, son of Yansanya, built extensive trenches around the chiefdom to protect it from raids from the
Warusha. •
Chiefdom of Manushi; Yansanya, the first ancestor to the royal Orioc clan, settles here at the village of Marawa after staying in Kinduchi. •
Kibosho Colony of Uru juu (Shimbwe); Eventually united with Uru chini to become a Unified kingdom in the 20th century. •
Kibosho Colony of Uru Chini (Kimanganuni); United with Uru Juu to become a separate kingdom in the 20th century. Kimanganuni becomes the center of the Uru Kingdom. •
Kibosho Colony of Kindi; Lost a lot of its residents to Arusha Juu (modern-day Arusha) fleeing Mangi Lokila and settled there. During its time as a colony, Kindi was forced into assassinating Kibosho cultures and languages. •
Kinduchi; a major settlement located in Lyamungo Chiefdom where the ancestor of the royal clan Yansanya first settled, coming from Siha in the west. This settlement is also the location of Mangi Sina's infamous young initiates massacre in the 19th century. ==Kibosho's golden age==
