Importance of a Count Palatine in Medieval Europe
Comes palatinus
This Latin title is the original, but also pre-feudal: it originated as a Roman Comes, which was a non-hereditary court title of high rank, the specific part palatinus being the adjective derived from palatium ('palace').
But after the fall of Rome, a new feudal type of title, also known simply as palatinus, started developing. The Frankish kings of the Merovingian dynasty (reigned 480-750) employed a high official, the comes palatinus, who at first assisted the king in his judicial duties and at a later date discharged many of these himself. Other counts palatine were employed on military and administrative work.
In Visigothic Spain, the Officium Palatinum consisted of a number of men with the title of count that managed the various departments of the royal household. The Comes Cubiculariorum oversaw the chamberlains, the Comes Scanciorun directed the cup-bearers, the Comes Stabulorum directed the equerries in charge of the stables, etc. The Ostrogothic kings that ruled in Italy also maintained palatine counts with titles such as Comes Patrimonium, who was in charge of the patrimonial or private real estate of the king, and others.
