Wilhelmshaven is a coastal town in Lower Saxony, Germany. It is situated on the western side of the Jade Bight, a bay of the North Sea.
The Siebethsburg castle, built before 1383, was occupied by pirates and destroyed in 1433 by the Hanseatic League. Four centuries later, the Kingdom of Prussia planned a fleet and a harbour on the North Sea. In 1853, Prince Adalbert of Prussia arranged the Jade Treaty (Jade-Vertrag) with the Grand Duchy of Oldenburg, in which Prussia and the Grand Duchy entered into a contract: 3.13 km² of Oldenburgian territory at the Jade Bight should be ceded to Prussia. In 1869, King William I of Prussia (later also German Emperor) founded the town as an exclave of the Province of Hanover as a naval base for Prussia’s developing fleet. All the hinterland of the city remained as part of the Duchy of Oldenburg.
