High Quality Content by WIKIPEDIA articles! Walram I of Nassau (French: Valéran) (born ca. 1146; died 1198) was the first (legally-titled) Count of Nassau, reigning from 1154 to 1198. The House of Nassau would become an important aristocratic family in Germany, from which are descended the present-day rulers of both the Netherlands and Luxembourg.Walram was the younger son of Count Robert I (German: Ruprecht) of Nassau and an unknown mother. She may have been Robert I's wife, Beatrix of Limburg (ca. 1115 - ca. 1164), daughter of Walram II the Pagan, Count of Limburg and Duke of Lower Lorraine and Jutta of Guelders (daughter of Gerard I, Count of Guelders), but this is considered unconfirmed by some historians.
