After World War I, Allied leaders sought to organize Europe into nation-states by drawing new borders and creating new countries. They approached this task through various methods, such as the creation of the League of Nations, the Treaty of Versailles, and the principle of self-determination. However, their efforts were not entirely successful. One example is the case of Czechoslovakia, which was created as a nation-state for the Czechs and Slovaks. Despite initially being prosperous, it faced several challenges, including ethnic tensions between Czechs and Slovaks, the economic impact of the Great Depression, and the rise of Nazi Germany. Another example is Yugoslavia, which was formed by various ethnic groups, including Serbs, Croats, and Slovenes. Although the country initially thrived, it eventually faced tensions among these groups, leading to its dissolution and the outbreak of ethnic conflicts in the 1990s. Lastly, the creation of Poland as a nation-state was hindered by ongoing conflicts with neighboring countries, such as the Soviet Union. While Allied leaders made efforts to organize Europe into nation-states, the complexity of ethnic, political, and economic factors hindered their success in fully establishing stable and harmonious countries.
