The result of the Treaty of Versailles on post-World War I international relations was significant and contentious. Signed in 1919, the treaty imposed harsh penalties on Germany, including substantial reparations and territorial losses, which fostered resentment. It aimed to create a new balance of power but instead contributed to political and economic instability in Germany, leading to the rise of totalitarian regimes. The treaty also established the League of Nations, intended to promote peace, although it ultimately failed to prevent future conflicts, setting the stage for World War II due to unresolved tensions.
