Prince of Orange is a title originally associated with the sovereign Principality of Orange, in what is now southern France.
 Under the Treaty of Utrecht of 1713, Frederick William I of Prussia ceded the Principality of Orange to King Louis XIV of France (while retaining the title as part of his dynastic titulature).
 After William III of England died without children, a dispute arose between Johan Willem Friso and Frederick I of Prussia, which was settled in the Treaty of Partition (1732); consequently, Friso's son, William IV had to share use of the title "Prince of Orange" (which had accumulated prestige in the Netherlands and throughout the Protestant world) with Frederick William I of Prussia.
 The title is traditionally borne by the heir apparent of the Dutch monarch.
 The title descends via absolute primogeniture since 1983, meaning that its holder can be either Prince or Princess of Orange.
