All of the diverse societies that made up the long continuum of Mesopotamian history were ruled by kings, and those kings were men. Only one woman was ever acknowledged as a ruler in her own right. According to the Sumerian King List, Ku-Baba, a tavern woman, ruled Kish as king (not queen) for a hundred years during the third millennium. Ku-Baba, about whom we know little else, remained an anomaly, however (Jacobsen 1939b: 104-5).
Although women could not be rulers and were, like everyone else, subordinate to them, those women who were closest to the king - his wife or wives, mother, sisters, and daughters - did take part in political, administrative, and religious life. Women who exercised power did so on behalf of their husbands or sons, rather than independently, and the power they wielded derived from typical female activities such as marriage, childbirth, or household management. The women of the royal household could be extremely valuable to the king or his heirs, and these women were often active, dynamic contributors to their family’s interests. Ideally, members of the royal family, including the king, acted to further the interests of what was essentially a corporate body, that is, the family, tribe, or dynasty. Royal women did not exist in marginalized isolation, but played vital roles that were developed to fulfill both political needs and social requirements.
We cannot expect that women of all periods or in all places experienced life in the same way. The evidence concerning royal women is incomplete and difficult to interpret: sometimes plentiful and varied, sometimes scarce or overly specific. The different types of evidence we encounter range from economic documents, letters, and monumental inscriptions to artistic representations, jewelry, and other personal items, but rarely, if ever, do we have anything like a complete array of evidence for any one woman let alone a single time or place. In spite of the often frustrating lack of data, there is still too much to consider thoroughly here. Therefore, I have chosen examples from different periods and areas of Mesopotamia that illustrate particular points especially well.
