1. Forms of Government
Different societies have adopted various forms of government throughout history. Understanding these systems is the foundation of political literacy.
Democracy — A system of government in which power is vested in the people, who exercise it directly or through elected representatives, based on principles of equality and freedom.
Republic — A form of government in which the country is considered a public matter, with elected officials representing the citizenry rather than a monarch holding hereditary power.
Autocracy — A system of government in which supreme power is concentrated in the hands of one person, whose decisions are not subject to legal restraints or democratic oversight.
Federal system — A mode of government that divides sovereignty between a central authority and constituent political units such as states or provinces, each retaining certain autonomous powers.
Parliamentary system — A form of government in which the executive branch derives its legitimacy from and is accountable to the legislature, with the head of government typically being the leader of the majority party.
Each form of government reflects different assumptions about authority, representation, and the role of citizens. These foundational concepts shape every other aspect of political life.
2. Branches of Government
Most modern democracies divide governmental power among distinct branches to prevent the concentration of authority and ensure accountability through checks and balances.
