Concept:The rule of law is the foundation of democracy because it guarantees equality and fairness for all citizens before the law.Explanation:Democracy is a system of government in which power belongs to the people. It thrives on the principle that every person is equal before the law. The rule of law means that no one, no matter how highly placed, is above the law. In a democracy, this principle ensures that all citizens are treated fairly and protects them from arbitrary or oppressive governance.

These systems do not depend on the rule of law because their rulers may act without legal restraint.
