First Hanseatic Diet
A merchant league controls trade from Novgorod to London

In 1356, by one account, the Hanseatic towns held their first general diet, the Hansetag, in Lübeck. The league of merchant guilds and towns spanned nearly 200 settlements, dominated trade on the North and Baltic Seas, kept kontors in Novgorod, Bergen, Bruges and London, and finally dissolved only in 1669.
