  The district duchy, also known as the district principality, was a type of the state under the patrimonial system, such as duchy or principality, formed in the feudal system, as a result of land partition between the members of a royal family. It occurred in the Middle Ages and early modern period, notably in Europe, in states such as the Holy Roman Empire, Duchy of Poland, and Kievan Rus'.
