Samland

Samland was a Prussian bishopric on the Baltic coast, with its seat at Fischhausen. Founded in 1243, it was closely tied to the Teutonic Order, whose vassal Bishop Johan was in 1337.

Its territory briefly passed to Poland in 1454 before returning to the Order as a Polish fief. The bishop introduced the Reformation in 1523; after the creation of secular Ducal Prussia in 1525, the Lutheran bishopric gradually faded. The Catholic see was formally dissolved in 1821.
