Few countries have suffered more from the convulsions and bloodshed of twentieth-century Europe than those in the eastern Baltic. Small nations such as the Baltic States of Latvia and Estonia found themselves caught between the giants of Germany and Russia, on a route across which armies surged or retreated. Subjected to foreign domination and conquest since the Northern crusades in the twelfth century, these lands faced frequent devastation as Germans, Russians and Swedish colonisers asserted control of the territory, religion, government, culture and inhabitants.
