The Hanseatic League was a union of ports on which sea?
Hanseatic League Hanseatic League The Hanseatic League (; Middle Low German: "Hanse", "Düdesche Hanse", "Hansa"; Standard German: "Deutsche Hanse"; Dutch: "Hanze"; Latin: "Hansa Teutonica") was a commercial and defensive confederation of merchant guilds and market towns in Northwestern and Central Europe. Growing from a few North German towns in the late 1100s, the league came to dominate Baltic maritime trade for three centuries along the coasts of Northern Europe. Hansa territories stretched from the Baltic to the North Sea and inland during the Late Middle Ages, and diminished slowly after 1450. "Hanse", later spelled as "Hansa", was the Old High German word
Hanseatic League were manufactured in northern Germany. The same refinement of products out of cottage industry occurred in other fields, e.g. etching, wood carving, armour production, engraving of metals, and wood-turning. The century-long monopolization of sea navigation and trade by the Hanseatic League ensured that the Renaissance arrived in northern Germany long before the rest of Europe. In addition to the major "Kontors", individual Hanseatic ports had a representative merchant and warehouse. In England this happened in Boston, Bristol, Bishop's Lynn (now King's Lynn, which features the sole remaining Hanseatic warehouse in England), Hull, Ipswich, Norwich, Yarmouth (now Great Yarmouth), and York.
