1. INTRODUCTION
Aristotle is often called the “Father of Political Science” because he was the first to undertake a systematic, empirical, and scientific study of constitutions.
He and his students collected and analyzed 158 constitutions of Greek city-states.
His conclusions appear in Politics (Book III & IV).
Aristotle’s classification is:
- descriptive
- realistic
- based on actual political life
- not utopian (unlike Plato)
It remains one of the most influential typologies in political theory.
2. WHY ARISTOTLE STUDIED CONSTITUTIONS
Aristotle believed:
- the state exists for the sake of the good life,
- the constitution determines who rules and in whose interest.
Every state has a constitution because the constitution defines:
- distribution of power
- duties of citizens
- form of government
- nature of justice
Thus, classifying constitutions helps understand:
- stability of states
- causes of revolution
- best possible forms of rule
3. BASIS OF ARISTOTLE’S CLASSIFICATION
Aristotle uses two criteria:
Criterion 1: Number of rulers
- One
- Few
- Many
Criterion 2: Purpose of rule
- In the common interest → Correct (Ideal) Forms
- In the self-interest of rulers → Deviant (Corrupt) Forms
This leads to six kinds of constitutions.
4. THE TWO PRINCIPLES
4.1 Correct (Ideal) Forms — Rule in the Interest of All
These serve the common good:
- Monarchy – Rule by one virtuous king
- Aristocracy – Rule by few virtuous persons
- Polity – Rule by many; a mixed and moderate government
4.2 Deviant (Perverted) Forms — Rule in Interest of Rulers
These serve private interest:
- Tyranny – Corrupt monarchy
- Oligarchy – Rule of the rich few
- Democracy – Rule of the poor masses only for themselves
(Note: Aristotle does NOT condemn “democracy” as modern democracy. He refers to extreme mob rule.)
5. ARISTOTLE’S SIXFOLD CLASSIFICATION OF CONSTITUTIONS
Below is a detailed explanation of each.
5.1 MONARCHY (Ideal Rule by One)
Definition
Rule of one person based on:
- virtue
- wisdom
- public benefit
Characteristics
- king acts as the father of his people
- guided by justice
- stable and orderly
- suitable for small states
Merit
Quick decisions, unity.
Demerit
High chance of becoming a tyranny.
5.2 ARISTOCRACY (Ideal Rule by Few)
Definition
Rule by a small group of:
- the best
- the wise
- the virtuous
Aristocracy = government of the morally superior.
Characteristics
- rulers prioritise the common good
- power given based on merit
- promotes justice
Threat
May descend into an oligarchy.
5.3 POLITY (Ideal Rule by Many)
This is Aristotle’s most practical and realistic constitution.
Definition
A mixed constitution:
- rule by many (middle class)
- blend of democracy + oligarchy
- moderation and stability
Key Features
- strong middle class prevents conflict
- rule of law
- moderate wealth distribution
- citizen-soldiers
- balanced participation
Why Aristotle prefers Polity:
- avoids extremes
- stable
- realistic for most states
- promotes moderation
- protects freedom & order
Polity is essentially an early model of modern mixed government.
5.4 TYRANNY (Corrupt Rule by One)
Definition
Monarchy corrupted into:
- rule by one for his personal benefit
Characteristics
- cruel
- oppressive
- arbitrary
- fear-based rule
- no law or justice
Aristotle calls tyranny the “worst” constitution.
5.5 OLIGARCHY (Corrupt Rule by Few)
Definition
Rule by the rich few for their own economic interests.
Characteristics
- concentration of wealth
- exclusion of poor from power
- class conflict
- social injustice
Threat
Revolutions by the poor → collapse into democracy.
5.6 DEMOCRACY (Corrupt Rule by Many)
Warning: Aristotle’s democracy ≠ modern liberal democracy.
Definition
Rule of the poor majority for their own interest, ignoring minorities.
Characteristics
- mob rule
- instability
- disregard for law
- populism
- redistribution of wealth for personal gain
Aristotle criticizes extreme democracies but favors moderate democracy within polity.
6. FEATURES OF EACH CONSTITUTION (Detailed Table)
| Number of Rulers | Correct Form | Deviant Form |
|---|---|---|
| One | Monarchy | Tyranny |
| Few | Aristocracy | Oligarchy |
| Many | Polity | Democracy |
7. TRANSITION FROM ONE CONSTITUTION TO ANOTHER
Aristotle explains natural cycles:
- Monarchy → Tyranny
- Aristocracy → Oligarchy
- Polity → Democracy
And reverse:
- Democracy → Tyranny (via demagogues)
- Oligarchy → Tyranny (via elite power grab)
He sees political change as a cyclical, organic process.
8. WHY POLITY IS ARISTOTLE’S BEST PRACTICAL CONSTITUTION
Aristotle prefers Polity because:
- Middle class dominance prevents extremes
- Combines best of democracy and oligarchy
- Stable and moderate
- Rulers obey rule of law
- Encourages civic participation
- Protects common interest
Thus it becomes a balanced constitution.
9. ARISTOTLE’S MIXED CONSTITUTION
Polity blends:
- democracy → participation & equality
- oligarchy → order, stability, merit
The result is:
- shared power
- compromise
- checks on extremes
It resembles modern:
- constitutional government
- separation of powers
- rule of law systems
10. COMPARISON OF ALL SIX CONSTITUTIONS
| Form | Rulers | Aim | Strength | Weakness |
|---|---|---|---|---|
| Monarchy | One | Common good | Unity | Tyranny risk |
| Aristocracy | Few virtuous | Common good | Merit-based | Can become oligarchy |
| Polity | Middle class many | Common good | Stability | Hard to maintain balance |
| Tyranny | One | Private interest | Quick decisions | Cruel, unstable |
| Oligarchy | Rich few | Private wealth | Economic efficiency | Inequality, revolt |
| Democracy | Poor many | Private interest | Participation | Mob rule, instability |
11. CRITICISMS OF ARISTOTLE’S CLASSIFICATION
- Based on Greek city-states — too small for modern states
- Negative view of democracy is outdated
- Ideal constitutions depend heavily on virtue
- Overemphasis on class divisions
- Accepts slavery and citizen-exclusion
- Too moralistic — modern politics is more institutional
But despite criticisms, Aristotle’s model remains foundational.
12. MODERN RELEVANCE
Aristotle’s ideas influence:
- constitutional design
- comparative politics
- mixed government models
- theory of the middle class
- stability vs. conflict studies
- separation of powers
- balanced democracies
- modern republicanism
His insight that middle class stabilizes democracy is widely accepted today.
13. SUMMARY (Quick Revision)
- Aristotle created the first scientific classification of constitutions.
- Based on number of rulers & purpose of rule.
- Six constitutions: Monarchy, Aristocracy, Polity (ideal), and Tyranny, Oligarchy, Democracy (corrupt).
- Polity is his preferred practical constitution → a balanced mix of democracy and oligarchy.
- Extremes of wealth or poverty destabilize states.
- His theory helps understand political change, revolutions, and stability.
- Despite limitations, his classification remains foundational in political science.
