A Voivodeship, also spelled '''Voivodship''', '''Voivodina''' or '''Vojvodina''' () was initially the military commander next to the ruler.
The term voivodeship is used in the native languages for the 16 Voivodeships Of Poland , and for the Autonomous Province of Vojvodina in Serbia, and has found its way into English in some of the larger dictionaries such as the OED and Webster's Third New International Dictionary , though it is not in common usage. Depending on the historical context in which it is used, it is translated variously as duchy, province, palatinate, or administrative district. The appropriate translation in modern usage is "administrative district", although "province" also functions as an adequate and more usable equivalent.
