The Hanseatic League^[a] was a medieval commercial and defensive network of merchant guilds and market towns in Central and Northern Europe. Growing from a few North German towns in the late 12th century, the League expanded between the 13th and 15th centuries and ultimately encompassed nearly 200 settlements across eight modern-day countries, ranging from Estonia in the north and east, to the Netherlands in the west, and extended inland as far as Cologne, the Prussian regions and Kraków, Poland.

The League began as a collection of loosely associated groups of German traders and various towns aiming to expand their mutual commercial interests, including protection against robbery. Over time, these arrangements evolved into the Hanseatic League, offering traders toll privileges and protection on both affiliated territory and their trade routes. Growing economic interdependence and familial connections among influential merchant families led to deeper political integration and the removal of trade barriers. This gradual process also saw the emergence of standardized trade regulations among Hanseatic Cities.

During its zenith, the Hanseatic League dominated maritime trade in the North and Baltic Seas. It established a network of trading outposts in numerous towns and cities, notable among them the Kontors in London (known as the Steelyard), Bruges, Bergen, and Novgorod, which became extraterritorial entities that enjoyed considerable legal autonomy. Hanseatic merchants, commonly referred to as Hansards, operated in basic private companies and were widely known for their access to a variety of commodities, and enjoyed privileges and protections abroad. The collective economic power made the League capable of imposing blockades and even waging war against kingdoms and principalities.

Even at its peak, the Hanseatic League was never more than a loosely aligned confederation of city-states. It lacked a permanent administrative body, a treasury, and a standing military force. In the 14th century, the Hanseatic League instated an irregular negotiating diet (Middle Low German: dachvart or dach; German: Tagfahrt or Hansetag) that operated based on deliberation and consensus. By the mid-16th century, these weak connections left the Hanseatic League vulnerable, and it gradually unraveled as members became consolidated into other realms or departed, ultimately disintegrating in 1669.

The Hanseatic League used a variety of ship types for travel across the seas and along rivers. The most emblematic type was the cog. Knowing great diversity in construction, it was depicted on Hanseatic seals and coats of arms. By the end of the Middle Ages, the cog was replaced by other types like the hulk, which later gave way to larger carvel types.
