20th-century dictatorships

20th-century dictatorships were authoritarian regimes where a single leader or party held significant power, often suppressing opposition and dissent. Examples include Adolf Hitler's Nazi Germany, Joseph Stalin's Soviet Union, and Mao Zedong's China. These regimes typically used propaganda, censorship, and state violence to maintain control and promote their ideologies. Economic crises, social unrest, or political instability often facilitated their rise. Dictatorships resulted in widespread human rights abuses, including mass imprisonment, torture, and genocide, profoundly impacting global politics, society, and history. Understanding these regimes highlights the consequences of power concentrated in the hands of a few.
