The word Mthwakazi was derived from the name of Queen MuThwa, the first ruler of Mthwakazi territory. The Muthwa pseudo-dynasty survived up to around the 18th century. She was the matriarch of the abaThwa, the San people. With the arrival of Bantu people, Mthwakazi territory became, increasingly, a center of diverse cultures. These local groups maintained their local autonomy, however, boundaries were fluid and intermarriages were common. The later arrival of the Nguni peoples, in the late 18th century and early 19th century, saw the intercultural society of Mthwakazi evolving into a sovereign state that was recognized by both neighbouring African states and foreign powers. The area has a long history of diverse cultures and arts.
Imbongi (poets) began poetically describing the wonderful social structure of Mthwakazi with references like
uMbuthwa okazi (the great collective union).
Mzilikazi is said to have marvelled at the great diverse and collective union saying "Saze sabasihle isizwe sakoMthwakazi, uMbuthwa okazi!, undlela zimhlophe!, njenginsimu yamaluba", loosely translated as: "O, how beautiful, great and diverse the union is. It is like a garden of flowers". Several peace treaties, marking the borders of Mthwakazi, were signed and the new land existed as a nation. However, the colonial powers, occupying the eastern neighbouring state at the time (British Mashonaland Protectorate), later disregarded these agreements and invaded Mthwakazi on 3 November 1893. Mthwakazi fought a bitter defensive battle at Gadade, Mbembesi, but was overpowered by the enemy which used an arsenal of arms which were technologically more advanced than that of Mthwakazi warriors, hence lost and so began a long period of occupation and rule by conquest. Mzilikazi's settlement in what is now Matabeleland, Zimbabwe, can be described as a transformative and strategic occupation, marked by his establishment of a powerful, centralized Ndebele kingdom. After leading his followers northward during the Mfecane, Mzilikazi arrived in the region around the 1830s. His arrival brought military strength, Zulu-influenced tactics, and a hierarchical social organization, which were instrumental in his ability to establish dominance. The territory he settled, later called Mthwakazi by the Ndebele, was previously inhabited by groups like the Kalanga and Rozvi, whose societies were impacted by Mzilikazi's expansion. Mzilikazi's settlement involved both conquest and incorporation: he subdued local communities but also assimilated many of their people into the Ndebele social structure. This assimilation created a multi-ethnic society under Ndebele rule, with a centralized authority that imposed Ndebele language and customs, while allowing for some preservation of local identities within a tributary framework. Through this process, Mzilikazi transformed Mthwakazi into a cohesive and influential kingdom. His rule brought stability to the area after the disruption of the Mfecane, establishing the Ndebele as a major political and military power in the region, which would remain significant until British colonial occupation in the late 19th century. These Shona groups built stone structures such as khami and the great Zimbabwe ruins. The ethnic groups which were found in this "unnamed" area are the Kalanga, Venda, Xhosa, Sotho, Nambya, Tonga and the Karanga, Zezuru, Korekore, Ndau and Manyika (made up the eastern Shona dialects). The kingdom united the Kalanga tribe, the Wewuska tribe, the Ngsma tribe and the Tafaka tribe under a strong leadership . This kingdom was often attacked from the south by Vendas and Sotho, east by the Shona and west by the Tswana. His arrival was very welcomed as he gave military support to Mambo's kingdom. Ndebele children played and sang a song, "Kudala kwakunganje, umhlaba uyaphenduka, kwakubusa uMambo no Mzilikazi" loosely translated as "A long time ago, it wasn't like this, Mambo and Mzilikazi ruled together." One thing to point out was that there were many different tribes living in this large territory. The Kalanga people can be seen in Botswana and Zimbabwe, just like the Nambya and Tonga are both in Zambia and Zimbabwe for example. These tribes and others were assimilated by the Ndebele in Zimbabwe. With time, due to absolute power Mzilikazi was gaining, Mthwakazi developed into a Kingdom. ==Mthwakazi under Lobengula's leadership==
