Marriage was patrilocal. Polygamy was practiced mostly by people of higher, especially chiefly, status. Marriage was preferred with a close or classificatory cousin, especially a mother's brother's daughter, but this preference was most often realised in the case of ruling or chiefly families. Practiced by the ruling dynasty, during its period of dominance, it represented a system of political integration and control recycling of bridewealth (dikgomo di boela shakeng; returning of bride cattle). Cousin marriage meant that the two sets of prospective in-laws were closely connected even before the event of a marriage, and went along with an ideology of sibling-linkage, through which the bogadi (bridewealth) procured for a daughter's marriage would, in turn, be used to get a bride for her brother, and he would repay his sister by offering a daughter to her son in marriage. Cousin marriage is still practiced, but less frequently. Polygyny too is now rare, many marriages end in divorce or separation, and a large number of young women remain single and raise their children in small (and often very poor) female-headed households. But new forms of domestic co-operation have come into being, often between brothers and sisters, or matrilineally linked relatives.
