Valdemar is a Scandinavian given name, originating as a form of Waldemar, and also used as a translation of the Slavic name Vladimir. The name is composed of Old High German elements meaning "power" or "brightness" (wald) and "fame" (mar). Introduced to Scandinavia through the 12th-century Danish king Valdemar I, who was named after his maternal grandfather, Vladimir II, a grand prince of Kievan Rus, the name became established in royal dynasties. Etymology The name Valdemar derives from the Old High German elements wald ("power, brightness") and mar ("fame"). Its Old Norse equivalent is Valdamarr, which appears in the Poetic Edda in the Guðrúnarkviða II as the name of a Danish king. In the Heimskringla, the name refers to a ruler of Holmgard (modern Veliky Novgorod), and the Fagrskinna uses it for both Vladimir the Great and Vladimir Yaroslavovich. Royal Bearers The name boasts a strong royal heritage, borne by four kings of Denmark and one king of Sweden. Valdemar I of Denmark (1131–1182), also known as Valdemar the Great, was the first to popularize the name in Scandinavia. Later Danish kings include Valdemar II (1170–1241), Valdemar III (1314–1364), and Valdemar IV (1320–1375). In Sweden, Valdemar Birgersson (1239–1302) reigned from 1250 to 1275. Variants and Related Forms Valdemar has several variants across languages. The Portuguese form Valdemir is common in Brazil, and Valdomiro also exists. The Finnish diminutive Valto is used as a short form. Other cultural equivalents include the Latvian Voldemārs and its diminutive Valdis, Lithuanian Valdemaras, Polish Waldemar, and the Anglo-Saxon Wealdmær. Cultural Significance Valdemar is the Scandinavian cognate of the Slavic names Vladimir and Włodzimierz, reflecting historical connections between Norse and East Slavic peoples through trade and dynasty.
