Constitutionalism is a political system that emphasizes limiting government power by ensuring it operates within a constitutional framework, protecting citizens' fundamental rights and freedoms. This system typically includes the separation of powers (such as the division of legislative, executive, and judicial branches), the rule of law (where everyone, including the government, is subject to the law), and the protection of human rights. The goal is to constrain government authority through laws, preventing authoritarianism and abuse of power, and safeguarding individual rights.
