Which treaty officially ended World War I?

The Treaty of Versailles

The Treaty of Versailles, signed on June 28, 1919, in the Hall of Mirrors at the Palace of Versailles, not only marked the official end of World War I but also redrew the map of Europe. By imposing heavy financial reparations and severe military restrictions on Germany, the treaty sowed the seeds of discontent that would lead to World War II. Ironically, while it aimed to establish lasting peace, the treaty became a symbol of injustice for many, illustrating how the consequences of peace treaties can shape the global future long beyond their signing.
