After the fall of the Western Roman Empire, many tribes migrated into western Europe, causing strife and war. The answer to recurrent invasion was to create fortified areas which evolved into castles. Some leaders gained control of several areas, each with a castle. The problem lay in exerting proper control and authority in each area when a leader could only be in one place at a time. To answer this, lords gave their trusted vassals direct control of a castle, reporting to the lord only. In the ninth century, as fortifications improved and kings had difficulty making their subordinates pay their taxes or send the military aid the kings demanded, the castellans grew in power, holding their fief without much concern for their overlord's demands.

Usually the duties of a castellan were combined with the duties of a majordomo. This made the castellan responsible for a castle's domestic staff and its garrison, as well as a military administrator responsible for maintaining defenses and protecting the castle's lands. This was particularly the case if there was no lord resident at the castle, or if the resident lord was frequently absent. A castellan may exercise the power of the "ban" - that is, to hear court cases and collect the fines, collect taxes from residents, and muster local men for the defense of the castle. Castellans had both the power of low justice and high justice, which allowed them to implement up to and including the death penalty.

Nottingham Castle is a castle in Nottingham, England. It is located in a commanding position on a natural promontory known as "Castle Rock", with cliffs 130 feet high to the south and west. In the Middle Ages it was a major royal fortress and occasional royal residence.
