Political revolutions are significant changes in a country's government or political system, often resulting from widespread dissatisfaction among the people. These revolutions can lead to the overthrow of existing leaders or regimes, as seen in events like the French Revolution or the American Revolution. People usually seek more rights, freedom, or a fairer system, which can spark protests and uprisings. During a political revolution, new ideas about governance and society often emerge, challenging traditional beliefs. For instance, the Russian Revolution introduced concepts like communism, reshaping the nation and influencing others worldwide. Ultimately, revolutions can lead to both positive and negative outcomes, depending on how power is redistributed.
