The Treaty of Stralsund (Danish: Stralsundfreden 1370, sgd 24 May 1370) ended the Second Danish-Hanseatic War between the Hanseatic League and the Kingdom of Denmark.

[1][2][3]The war began in 1361 when Danish king Valdemar Atterdag conquered Scania, Öland, and Gotland with the major Hanseatic town Visby.

This led Hansa to accept a truce culminating in the unfavourable Treaty of Vordingborg, depriving the league of many of its privileges.

[2] Valdemar and his Norwegian son-in-law Haakon VI were utterly defeated in the following battles[3] The treaty was negotiated for Denmark by Drost Henning Podebusk and for the Hanseatic League by the burgomasters Jakob Pleskow of Lübeck and Bertram Wulflam of Stralsund.

Furthermore, Denmark had to assure the Hanseatic League of free trade in the entire Baltic Sea.
