In Tanzania prior and during colonialism the newcomers from Belgian Congo collectively termed Wamanyema were politically included with the remained minority autochthonous Jiji population mainly by indirect rule under the local authority of the Arab-Swahili Liwalis of Ujiji with local representatives to the town council with their old dynasties being disregarded and remained active ritually within their respective clans.

One of the significant tribe of Wamanyema is the Wagoma who migrated en masse from ancient Ugoma which is now the northwestern corner of Lake Tanganyika in modern day Fizi and Kalemie of the Democratic Republic of Congo.

In Goma history the villages and hamlets were many before the emigration and wars and the traditional states comprised several number of them before the immigration of bembe people with significant numbers of chiefdoms or sultanates sometimes under the suzerainty of Uguhha Kingdom the southernmost goma state under the Bakwamamba Dynasty in modern Kalemie in Tanganyika district of Katanga Region in Democratic Republic of Congo.

The current Manyema Kolo of Ujiji is Othman Hamza Malilo II of the Royal House of Mwene Mbonwe itself being a branch of Basuma clan of Bahoma tribe of Zyoba ethnicity of Wamanyema.

At the past the predecessors were ex officio High Priests of traditional religion that was based on the worship of pantheon of spirits under the Supreme God, "Kabezha Mpung'u" who is said to be above the heavens and was never depicted figuratively.

The notion of Sacred Kingship remained intact under the Islamic spirituality with the Kolo or styled Sultan being considered the successor of Liwalis of Ujiji as the Muslim religious head of the riverain tribal lands from Utongwe, Ukaranga, Uguhha, Ugoma, Karamba, Ubwari, Massanze, Ubembe, Uvira to Rumonge.
