Castellany
A castellany was a district administered by a castellan.
Castellanies appeared during the Middle Ages and in most current states are now replaced by a more modern type of country subdivision.
The word is derived from castle and literally means the extent of land and jurisdiction belonging to a given castle.
It also renders equivalent, often cognate, terms in other languages. Examples of French châtelainies include the castellanies of Ivry-la-Bataille, Nonancourt, Pacy, Vernon and Gaillon, all in Normandy, which under in the treaty of Issoudun (1195, after a war with king Richard of England) were acquired for the French crown by Philip Augustus. Examples from Poland include Leczyca and Sieradz (both once a duchy), Spycimierz, Rozprza, Wolbórz and Wojnicz (in Cracow diocese) and Otmuchow in Silesia.
