The Baltic nobility was the privileged social class in the territories of today's Estonia and Latvia. It existed continuously since the Northern Crusades and the medieval foundation of Terra Mariana. Most of the gentry were Baltic Germans, but with the changing political landscape over the centuries, Polish, Swedish and Russian families also became part of the nobility, just as Baltic German families re-settled in e.g. the Swedish and Russian Empires. The nobility of Lithuania is for historical, social and ethnic reasons often separated from the German-dominated nobility of Estonia and Latvia.
This nobility was a source of officers and other servants to Swedish and Polish kings in 16th and particularly 17th centuries, when Couronian, Estonian, Livonian and Oeselian lands belonged to them. Russian emperors used Baltic nobles in government.
Most of the nobility was "recalled" by Hitler to Germany in late 1939, a few months prior to the annexation of Estonia and Latvia by the Soviet Union in June 1940. Nowadays it is possible to find the successors of the Baltic nobility all around the world.
Rural Estonia and Latvia was to a large extent dominated by a manorial estate system, established and sustained by the Baltic nobility, up until the declaration of independence of Latvia and Estonia following the upheavals after World War I. Broadly speaking, the system was built on a sharp division between the landowning, German-speaking nobility and the Estonian- or Latvian-speaking peasantry. Serfdom was for a long time a defining characteristic of the Baltic countryside and underscored a long-lasting feudal system, until its abolishment in the Governorate of Estonia in 1816, in the Courland Governorate in 1817 and in the Governorate of Livonia in 1819 (and in the rest of the Russian Empire in 1861). Still, the nobility continued to dominate the rural parts of Estonia and Latvia via manorial estates throughout the 19th century. However, almost immediately following the declaration of independence of Estonia and Latvia, both countries enacted far-reaching land reforms which in one stroke ended the former dominance of the Baltic nobility on the countryside.
