# Nassau

Nassau, derived from the town of Nassau on the Lahn River in Rhineland-Palatinate, Germany, gained historical significance through the House of Nassau. The noble dynasty later formed the Dutch royal House of Orange-Nassau following William I's inheritance of the Principality of Orange in 1544, leading to the adoption of the name Nassau across various locations and institutions worldwide. The name traces its etymology to German nass (wet) and Au(e) (floodplain).
