Political upheavals refer to significant and often sudden changes in a country's political landscape. These events can include revolutions, coups, or widespread protests that challenge existing authority or government structures. Such upheavals often arise from social, economic, or political grievances among the population, leading to demands for reform or change. During political upheavals, the stability of a nation can be threatened, resulting in conflict or violence. Historical examples include the French Revolution and the Arab Spring, where citizens sought to overthrow oppressive regimes. These events can reshape a nation's governance and influence global politics.
