Who had to take credit for World War 1?

The Treaty of Versailles, signed in 1919, placed the blame for World War I primarily on Germany and its allies, assigning them responsibility for the conflict. This was particularly encapsulated in Article 231, known as the "War Guilt Clause," which required Germany to accept responsibility and pay reparations. This imposition of blame contributed to economic hardship and political instability in Germany, ultimately leading to the rise of Adolf Hitler and World War II.
