Purveyance
（重定向自Purvey）
Purveyance is the right of the Crown to requisition goods and services for royal use, and was developed in England over the course of the late eleventh through the fourteenth centuries. In theory, the king's prerogative allowed him to collect goods needed for both household and military use, but the latter was discontinued in 1362. The primary problem with the system was that it was open to abuse from corrupt officials, who would often requisition goods and sell them for profit or use extortion and other means to obtain items or money that was not passed on or divulged to the king. Accordingly, English kings established numerous, though somewhat ineffectual, statutes in an attempt to limit the corruption.
