How did the world map change as a result of ww1?

World War I significantly altered the world map by leading to the collapse of several empires, including the Austro-Hungarian, Ottoman, German, and Russian Empires. New nation-states emerged in Europe and the Middle East, such as Czechoslovakia and Yugoslavia, while borders were redrawn, often without regard for ethnic or cultural divisions. The Treaty of Versailles and other peace agreements imposed territorial changes and mandates, reshaping global geopolitics and setting the stage for future conflicts.
