Jeverland refers to the northern part of the present-day district of
Friesland in northern Germany with the town of
Jever as the seat of its local government. The Jeverland was formed in the 15th century from the Barony of Jever, which itself descended from the
Banter Viertel, part of Östringen and the
Wangerland. The town of
Wilhelmshaven, founded in 1853, no longer belongs to Jeverland, but is an independent district. Despite that, the formerly independent church parishes of
Heppens und Neuende are on the town's territory. In earlier times, agriculture was the mainstay of Jeverland's economy.
