Abstract:
During the First World War the Principle of Nationalities (each nation to
have its national state), a prinsiple supported also by the USA, was crystallized and ac-
complished. On the ruins of the Austro-Hungarian Empire, Czechoslovakia proclaimed
itself independent, its borders being set up by the treaties system from Versailles. During
the years of the First Republic, Czechoslovakia has imposed itself as a state with a stable
economic development, with an authentic multiparty democracy. At the same time, being
supported by nazi Germany, the ethnic Germans from the Sudet region of Czechoslova-
kia ultimately requested the accession of this region to Germany. Otherwise, A. Hitler
threatened to start a war in support of the Germans from Sudet. The Great Powers got
involved. Hitler’s claims were met at the Munchen Conference. This fact led to the dis-
sapearance of Czechoslovakia from Europe’s political arena.
