The Treaty of Stralsund (24 May 1370) ended the Danish-Hanseatic War between the Hanseatic League and the kingdom of Denmark. The Hanseatic League reached the peak of its power by the conditions of this treaty.^[1][2][3]

The war began in 1361, when Danish king Valdemar Atterdag conquered Scania, Öland, and Gotland with the major Hanseatic town Visby.^[2] In 1362, a Hanseatic counterstrike was repelled by the Danish fleet at Helsingborg, which led Hansa to accept a truce culminating in the unfavourable Treaty of Vordingborg, depriving the league of much of its privileges.^[2] Unwilling to accept the treaty, the Hanseatic League, which used to be a trade league rather than a political union, raised a fleet through the Confederation of Cologne in 1367 and renewed their Swedish alliances.^[2] In the following battles, Valdemar and his Norwegian son-in-law Haakon VI were utterly defeated.^[2][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. In the treaty, the freedom of Visby was reestablished. Furthermore, Denmark had to assure the Hanseatic League of free trade in the entire Baltic Sea. The Danes had to waive taxes over German merchants in Scania as well. This gave the Hanseatic League a monopoly on the Baltic fish trade. The league also gained the right to veto against Danish throne candidates.^[2]
