The Treaty of Utrecht was signed in 1474 after the Anglo-Hanseatic War between England and the Hanseatic League. This naval war had begun in 1470 using the naval strategy of commerce raiding in the North Sea and the English Channel; one of the most successful men-of-war was the Peter von Danzig. Driven in the main by the cities Danzig and Lübeck, it was a war against increasing English pressure on the trade of the Hanseatic cities of the southern coast of the Baltic sea. England was bankrupt after years of war and mismanagement; pressure against Hanseatic cities trade on the southern coast of the Baltic sea had to be foregone, while Cologne and other German cities had opposed, and were therefore temporarily excluded from, the Hansa.
