The Hanseatic League was an alliance of trading cities that was established during the Late Middle Ages and Early modern period, c.13th- 17th centuries. This alliance was able to control trade monopoly along from the North Sea to the Baltic Sea along the Northern European coast. This alliance was also often referred to as the Hansa. There are many reasons other than the ones above that the Hanseatic cities are so significant from a historical point of view. Perhaps the biggest reason is the fact that the cities were controlled by their own law system and mutual aid.
Most historians have tracked the origins of the Hanseatic League to during the time period when Duke Henry the Lion of Saxony started to rebuild the Lubeck in 1159 in Northern Germany. This reconstruction occurred after Henry had helped to capture the town from Count Adolf II of Holstein. After this happened, Lubeck became one of the premier locations for trading along the cost and acted as a means of trading with towns over seas. These guilds were also referred to as Hansa. This is the reason that the Hanseatic League is something that so many different collectors and historians are always interested in learning more about this significant historical period. It is also the reason that rare artifacts and coinage from this time and area have started to become highly sought after by many collectors. This is the reason that it is important to have this type of information to collectors interested in purchasing these types of collectibles.
