right of first night; jus primae noctis; droit du seigneur
Historical term referring to the alleged right of a feudal lord to have sexual relations with a subordinate's bride on her wedding night. Used in discussions of medieval European customs.
There is a theory that the right of first night in medieval Europe was not actually widely practiced.
Compound of 初夜 (shoya, 'first night') and 権 (ken, 'right'). The term is a direct translation of the European concept, likely coined in modern times for historical discussions.
