History of Warfare Summary 9 - World War I 19 The League of Nations and Post-War World Changes

After World War I, the international community sought to establish a new order to prevent large-scale wars from occurring again. The concept of the League of Nations, proposed by U.S. President Woodrow Wilson, aimed to resolve disputes between nations through international cooperation. The League of Nations officially launched in 1920, with many countries participating as member states. However, the United States did not join the League of Nations as it failed to obtain ratification from the Senate. The war caused significant damage to Europe's economy and industrial facilities, and numerous soldiers and civilians died or were injured. The collapse of the German Empire, the Austro-Hungarian Empire, the Ottoman Empire, and the Russian Empire dramatically altered the political landscape of Europe. In Russia, a communist regime emerged through revolution, and new nations were formed in Central and Eastern Europe. The war also impacted colonial regions, serving as a catalyst for the further spread of nationalism and independence movements. World War I was more than just a military conflict; it became a crucial historical turning point that transformed 20th-century international politics and social structures.
