Count (redirected from Platelet count)

count

 or earl

European title of nobility, ranking in modern times directly below a marquess or (in countries without marquesses) a duke. In England the title of earl is the equivalent of count and ranks above a viscount. The wife of a count or earl is a countess. The Roman comes (“count”) was originally a household companion of the emperor; under the Franks he was a local commander and judge. The counts were later incorporated into the feudal structure, some becoming subordinate to dukes, though a few countships were as great as duchies. As royal authority was reasserted over the feudatories, which took place at different times in the different kingdoms, the counts lost their political authority, though they retained their privileges as members of the nobility.

Count 

(Russian, graf; from German Graf), in Western Europe during the early Middle Ages, a royal servitor. Beginning in the second half of the sixth century, a count in the Frankish state possessed his own district—the county—with judicial, administrative, and military authority. Gradually the post of count became hereditary. In the period of feudal disintegration, the count was a feudal sovereign; then, at the end of this period, he became a high aristocrat. The title of count is maintained to this day in most European countries with a monarchical form of government.

In Russia the title of graf was introduced in the 18th century by Peter I and was abolished in 1917.
