Frederik is the Danish, Dutch, and Low German form of Frederick, a name meaning "peaceful ruler" derived from the Old German elements fridu "peace" and rih "ruler, king". This name has been borne by nine kings of Denmark over the past 500 years, alternating each generation with the name Christian.Etymology and HistoryThe root name Frederick has a rich history across continental Germanic-speaking regions, borne by Holy Roman Emperors, German, Austrian, Scandinavian, and Prussian rulers. Notables include Frederick I Barbarossa (12th century), Frederick II (13th century), and Frederick the Great (18th century). The name was introduced to England by the Normans in the 11th century but quickly died out, later reintroduced by the German House of Hanover in the 18th century. Frederick Douglass (1818-1895), an American ex-slave and abolitionist leader, is a notable bearer outside Europe. In Denmark, Frederik has been a royal name, with King Frederik IX reigning from 1947 to 1972 and the current heir apparent being Crown Prince Frederik.Cultural SignificanceIn the Netherlands, Frederik is a traditional given name though its popularity has declined in recent decades. Danish Low German usage follows similar patterns. Diminutives include Fred, Freddy, Freek, Frits, and Rik in Dutch. Feminine forms are Frederikke and Rikke. The surname Frederiksen derives from this name.Meaning: peaceful rulerOrigin: Old German, adopted into Danish, Dutch, Low GermanType: given nameUsage regions: Denmark, Netherlands, Northern Germany
