A bailiwick is usually the area of jurisdiction of a bailiff, and may also apply to a territory in which the sheriff's functions were exercised by a privately appointed bailiff under a royal or imperial writ. The word is now more generally used in a metaphorical sense, to indicate a sphere of authority, experience, activity, study or interest. A bailiwick (German: “Ballei”) was also the territorial division of the Teutonic Order. Here, various “Komtur(en)” formed a Ballei province.
The term survives in administrative usage in the British Crown dependencies of the Channel Islands, which for administrative purposes are grouped into the two bailiwicks of Jersey (comprising the island of Jersey and uninhabited islets such as the Minquiers and Écréhous) and Guernsey (comprising the islands of Guernsey, Sark, Alderney, Brecqhou, Herm, Jethou and Lihou). Each Channel Island bailiwick is headed by a Bailiff.
