This article explores the roles imperial women played in the practices and systems of the northern states during the Sixteen Kingdoms (304–439) and Northern Dynasties periods (386–581), two of the most politically turbulent periods in Chinese history. The article will focus particularly on the absence of crown princesses and intermarriage practice in Northern Wei, and the appearance of coterminous empresses in Former Zhao and Northern Zhou. While a vast scholarship has viewed the rulership strategies and policies of the Northern Dynasties as a process of Sinicization, or one-sided acculturation, this article considers the perspective of the northern rulers who were aware of a multicultural populace. In an effort to shore up their power in court and rule effectively over a dispersed, heterogenous population, these northern rulers enforced agendas employing imperial women as the medium through which to engage elites of diverse backgrounds and tie these groups to their imperial families. Imperial women served in critical roles that brought to the court a delicate balance among various powerful factions, lending stability to the reigns of emperors and promoting cosmopolitanism in a period prior to Tang (618–907).
