Until the advent of European domination in the region, chieftaincy of the Thembu (and other tribes of the Xhosa nation) was by patrimonial decent, with the first son of the major wife (known as the Great House) becoming automatic heir, and the first son of the second wife (the highest of the lessor wives, also known as the Right Hand House) being relegated to creating a minor chiefdom. The sons of the third wife (known as the Left Hand House) were destined to become advisors to the chief.
