The Treaty of Versailles was a peace agreement signed on June 28, 1919, that officially ended World War I. It was negotiated by the Allied Powers, including countries like France, Britain, and the United States, and aimed to establish terms for peace and prevent future conflicts. The treaty imposed heavy reparations and territorial losses on Germany, which was blamed for the war. The treaty included several key provisions, such as the creation of the League of Nations, an international organization intended to promote peace. However, many of its terms were controversial and led to economic hardship in Germany, contributing to political instability and the rise of Nazism in the following years.
