Imperial Count (German: Reichsgraf) was a title in the Holy Roman Empire. In the medieval era, it was used exclusively to designate the holder of an imperial county, that is, a fief held directly (immediately) from the emperor, rather than from a prince who was a vassal of the emperor or of another sovereign, such as a duke or prince-elector. These imperial counts sat on one of the four "benches" of Counts, whereat each exercised a fractional vote in the Imperial Diet until 1806.
