Куршский залив
When Mindaugas, King of Lithuania, transferred most of Samogitia to the Livonian Order in 1257, Duke Alminas was elected as the Samogitian leader and organized resistance. In 1253, the Germans built the Memel Castle on the Curonian land in the strategically important spot where Dangė River meets the Curonian Lagoon. The new castle threatened Curonians and Samogitians.
