go Knez

Knez is a Slavic title found in most Slavic languages, and also in Romanian in the form cneaz, denoting a royal nobility rank. It is usually translated into English either as Prince or less commonly as Duke, however, both terms do not represent a sufficiently accurate translation, because Knyaz was derived from the Proto-Germanic kuningaz (king).[1] In Latin sources the title is translated as comes or princeps. The ruler title was in use until the early part of the 20th century for Slavic nobles.
