Government Classifications
Every government can be described along three separate axes at once: who holds power, how tightly that power is controlled, and how it is structurally organized. Most real governments combine one label from each.
Forms of Government, Who Holds Power
This axis asks a single question: who is entitled to govern? The answer might be no one at all, every citizen, a hereditary ruler, a small elite, a religious authority, or the most capable candidates by some measure of merit. The list below spans from the stateless societies of early antiquity through classical Greek and Roman variations to forms still active today, and it says nothing yet about how much that power is checked or how the state is structurally organized, those are the next two axes.
Putting It Together
These three categories are not mutually exclusive. A real government is usually described using one label from each, its form, its regime type, and its structure, combined into a single working picture of how the country is actually governed.
Ancient Sparta
Aristocracy and Stratocracy (Form, power held by a noble military class) combined with a council-based Structure built around its dual kingship and elder council.
Nazi Germany (1933 to 1945)
A Single-Party State practicing Totalitarianism (Regime) organized as a Unitary State (Structure), with all regional authority subordinated to the central Nazi government in Berlin.
United States (modern)
A Representative Democracy / Republic (Form) that functions as a Liberal Democracy (Regime), organized as a Federal, Presidential System (Structure).
Republic of Venice (697 to 1797)
An Oligarchy (Form, governing power restricted to noble merchant families) organized as a City-State (Structure).
United Kingdom (modern)
