The German Baltic Nobility refers to the aristocratic families that emerged in the Baltic Sea region, particularly in areas like Estonia, Latvia, and Lithuania. These families were primarily of German descent and played a significant role in the political, economic, and cultural life of the region from the Middle Ages until the 20th century. They often held large estates and were influential in local governance. During the Teutonic Order period, the German Baltic Nobility established a feudal system that shaped the social structure of the area. Their influence waned after the Russian Empire expanded into the region, but many noble families retained their status and properties, adapting to the changing political landscape.
