Totalitarian states arose in several European and Asian countries in the 1930s in response to economic hardship and nationalist sentiment following World War I. These regimes, led by figures like Stalin, Mussolini, and Hitler, promised to restore prosperity but ruled through oppression and violence. They pursued aggressive expansionist policies, with Germany rearming and invading neighboring lands while Japan invaded Manchuria and parts of China. Britain and France responded weakly, pursuing appeasement rather than standing up to the growing threats to peace.
