Timeline

1. c. 1150–1200Lübeck · Baltic SeaAfter its rebuilding, Lübeck became a transshipment hub linking Baltic salt and furs with Western European cloth and metals, and North German merchants began forming stable long-distance sea routes.
2. 1226Lübeck and Hamburg · Northern GermanyLübeck and Hamburg mutually recognized each other's city law and commercial customs, providing a model for later legal integration among Hanse cities and serving as a key institutional node of the league's precursor.
3. c. 1220–1300Bruges · FlandersFrom the 1220s German merchants established kontors in Bruges, London, Novgorod, and elsewhere, using collective bargaining to win tariff concessions and judicial autonomy.
4. c. 1300–1358North Sea–Baltic coasts · Baltic SeaRegular merchant assemblies and convoy alliances among 14th-century cities became increasingly institutionalized, and the 1358 Hanseatic diet at Lübeck marked the loose network's evolution into a formal league.
