The signing of the Treaty of Versailles was significant as it officially ended World War I and imposed harsh penalties and reparations on Germany. Signed on June 28, 1919, the treaty aimed to establish peace and prevent future conflicts. Key provisions included the disarmament of Germany, territorial losses, and significant reparations, which contributed to widespread resentment among Germans. The treaty also established the League of Nations, an early attempt at international governance, which was intended to resolve conflicts diplomatically. However, the treaty's punitive measures and failure to effectively address the underlying issues of the war are often cited as contributing factors to World War II.
