Answer:
Latvia
Czechoslovakia
Lithuania
Step-by-step explanation:
The borders of Europe were radically altered. Many of the changes came as a result of the Treaty of Versailles in 1919. Four different empires (the Austro-Hungarian, Ottoman, Russian, and German empires) came to an end. Replacing them were three new republics and a new communist state (Latvia, Czechoslovakia,Lithuania). From these former empires also came the new countries of Finland, Hungary, Austria, and Estonia.
