What happend to the land after world war 1?

After World War I, the Treaty of Versailles and other peace treaties resulted in significant territorial changes in Europe and beyond. Many empires, such as the Austro-Hungarian and Ottoman Empires, were dismantled, leading to the creation of new nations and borders. Some territories were transferred to other countries, while others were established as mandates under the League of Nations. This redrawing of boundaries often led to ethnic tensions and conflicts that continued for decades.
