Definition
Constitutional democracy is a form of government that combines two principles. It is democratic, because political authority rests with the people, usually exercised through free elections and chosen representatives. It is constitutional, because that authority is limited by a fundamental law — a constitution — that defines how power may be used and protects basic rights.
The constitution stands above ordinary legislation. Even an elected majority may not override the protections it guarantees, which prevents democracy from sliding into the unchecked rule of the majority.
Why it matters
How it works
A constitutional democracy works by dividing and binding power. Elections make rulers accountable to the governed, while a constitution sets the rules they must follow. Power is typically split among branches — legislative, executive, and judicial — so that each can check the others. Independent courts can strike down acts that violate the constitution. Because the rules are written and enforceable, citizens can demand that the state honor its own commitments, and disagreements are settled through law rather than force.
