What were some of the Obstacles to peace between 1918-1939?

Between 1918 and 1939, several obstacles to peace emerged, primarily stemming from the unresolved grievances of World War I. The harsh conditions of the Treaty of Versailles fostered resentment in Germany, leading to the rise of extremist movements like the Nazis. Additionally, the failure of the League of Nations to effectively mediate conflicts and enforce disarmament further weakened international security. Economic instability, exacerbated by the Great Depression, also fueled nationalism and militarism, making conflict more likely as countries sought to assert their power.
