Revolutions typically bring about significant changes in political systems, often dismantling existing governments and creating new governance structures. They occur as a response to widespread dissatisfaction with oppression or inequality, aiming to establish more representative systems. Post-revolution, societies may experience a shift toward democracy or, in some cases, a descent into authoritarianism or instability if new powers fail to address the people’s needs. Revolutions can also lead to profound cultural shifts, altering citizens' perceptions of authority and rights. Overall, revolutions are transformative events that can redefine national trajectories.
