The ImiDushane tribe was founded by one of the greatest Xhosa warriors Prince Mdushane who was the eldest son of Prince Ndlambe of the Rharhabe kingdom.
The ImiDushane are therefore a subgroup within the Xhosa nation and can be found in the Eastern Cape, South Africa where they have three Traditional Councils in Tamarha near King William's Town, Ncerha near East London and Centane in the Mnquma Local Municipality.
Although sometimes referred to as the ImiDushane kaNdlambe, the ImiDushane are a distinct tribe separate from the amaNdlambe, i.e. the tribe of Prince Ndlambe; having been established after Mdushane succeeded his uncle Prince Cebo who had died without male successors, as the heir to the Right Hand House of Rharhabe.
Rharhabe was the great son of the Right Hand House of King Phalo and is said to have been born around 1722. King Phalo was the last absolute ruler over a united Xhosa speaking people, which is now split between the amaGcaleka and the amaRharhabe Xhosa branches.
According to Xhosa tradition, King Phalo had intended to marry two royal brides from two different kingdoms for whom he had paid lobola. However, one day he was caught by surprised when both bridal parties arrived simultaneously at his great place to begin the wedding festivities. In order to avoid offending either father of the intended brides; Phalo was convinced by one of his councillors to marry both princesses on the same day, making one princess his wife from the Great House and the other, the wife of the Right Hand House. The two houses would be independent of each other and equal in status; thereby avoiding any confrontation with the two noble families.
The great wife would bear the heir to the throne being the representative of the senior line; while the great son of the Right Hand House would be independent of his brother and would in due course be able create his own kingdom. Phalo had two important sons from the two houses who would play a pivotal role in the history of the amaXhosa; Prince Gcaleka his heir, born from the Great House, and Prince Rharhabe who was the eldest, born from the Right Hand House.
