Of all groups, which belonged to the Ming inner court, the princesses have been the least studied as a research subject. These women have been much neglected for a long time. The main reason for this may be sources for a study of princesses at that time are abundant. This article hopes to present a picture of the emperors’ daughters in the Ming period, based on primary texts of the Ming and early Ch’ing times, including official books: biography of princesses in the Ming History, works on ritual, and other unofficial histories. This paper focuses on the life of princesses in the Ming dynasty. The first section describes activities from the birth of princess to title conferring. The second section discusses princesses’ participation in ritual, which is important for affirming the legitimacy of the imperial family. The third section discusses the marriage and family life of princesses and examines the policy of recruiting imperial members in the Ming times. Finally, the economic foundation of princesses will not be ignored, either.
