National revolutions are significant movements where a group of people seeks to change their government or political system, often aiming for independence or greater rights. These revolutions typically arise from widespread dissatisfaction with existing authorities, leading to protests, uprisings, or armed conflict. Examples include the American Revolution and the French Revolution, which sought to establish new forms of governance based on principles like liberty and equality. During national revolutions, various social classes and political factions may participate, each with their own goals and ideologies. The outcomes can vary widely, resulting in the establishment of new governments, changes in leadership, or even civil wars. The Haitian Revolution and the Russian Revolution are further examples of how these movements can reshape nations and influence global politics.
