Socialist revolutions are movements aimed at overthrowing existing political and economic systems to establish a society based on socialist principles. These revolutions often seek to redistribute wealth, promote social equality, and eliminate class distinctions. Notable examples include the Russian Revolution of 1917, which led to the rise of the Soviet Union, and the Cuban Revolution of 1959, which established a socialist government under Fidel Castro. Typically, socialist revolutions involve mass mobilization, grassroots organizing, and sometimes armed conflict. They can arise from widespread dissatisfaction with economic inequality, political oppression, or social injustice. The outcomes of these revolutions vary, with some leading to stable socialist states and others resulting in authoritarian regimes or civil unrest.
