Political theory is significant in understanding democracy as it provides frameworks for analyzing governance, individual rights, and the role of citizens. Theorists like John Locke and Alexis de Tocqueville contribute ideas that help us grasp the complexities of democratic systems. These theories address issues such as representation, legitimacy, and participation, illuminating how democratic principles can be realized or challenged in practice. By engaging with political theory, citizens can critically evaluate their own political systems and advocate for improvements that align with democratic ideals.
