Europe 1920: Treaty of Trianon

Due to the revolutions and invasions that followed the end of the Great War, it wasn’t until 1920 that Hungary was stable enough to sign its peace treaty with the Allies. The result was a much reduced state that had lost almost three-quarters of its territory and two-thirds of its population to Czechoslovakia, Romania, and Yugoslavia.
