Hendrik van Borssele Johann Lüneburg The Dutch–Hanseatic War[1] was a conflict between the County of Holland, acting independently of the rest of the Burgundian Netherlands of which it formed part, and the Hanseatic League.
It ended after Eric of Pomerania was forced from the throne of Denmark in 1440, and the new king Christopher of Bavaria sought a resolution.
[3] On 14 April 1438 a formal war was declared by the Dutch administration against the six Wendish cities of the League—Hamburg, Lübeck, Lüneburg, Greifswald, Stettin (now Szczecin) and Anklam—and the County of Holstein,[2] and on 23 April the Hanseatic League informed its member cities of the situation and advised shipping via Flanders, rather than Holland or Zeeland.
Little actual fighting took place throughout the war, though in May 1438 the Dutch mobilised all suitable ships in Holland and ordered the construction of 79 new vessels.
[2][3] The State of the Teutonic Order however declared itself neutral, and the cities in Prussia refused any military assistance to support the Hanseatic war effort.
