Lordship of Jever

The Lordship of Jever also known as Herrschaft of Jever, was a Herrschaft in the Free Frisian Lands, and later the Holy Roman Empire, it officially joined the Empire in 1548, when it became part of the Burgundian Circle. It came into existence when Edo Wiemken the Elder, the chief of multiple Frisian districts/ tribes, joined his realm into this nation, centered around the city of Jever. The territory came to somewhat of an end in 1624, when the last female heir (Maria von Jever) died without producing any valid heirs. The territory then fell under a personal union with Oldenburg until 1624, when the territory switched between many personal unions until it finally fell into the hands of Oldenburg again, which then finally fully annexed it in 1818.

Wars

 * Jever was most notably involved in multiple conflicts with the County of East Frisia, who claimed legitimate ownership of the land. East Frisia burned down the Jever castle in 1428, which led to the construction of the palace of Jever. The whole country was occupied by East Frisia from 1517 until 1531.
 * The Principality of Anhalt-Zerbst, which controlled the country from 1667 to 1793, rented some of Jever's soldiers out to the United Kingdom to help in the American Independence war.
