The Commonwealth of Oceana

In Short

Published in 1656 during the English Interregnum, The Commonwealth of Oceana is James Harrington’s foundational work of political philosophy. Presented as the utopian founding of a new state named Oceana, the text combines theoretical argument, historical analysis, and a detailed constitutional framework. Harrington asserts that political power naturally follows property ownership, particularly land. Through the figure of the lawgiver Olphaus Megaletor, the work outlines an intricate system of rotation in office, agrarian limits, and secret balloting. It remains a landmark text in early modern republican thought and political economic theory.

The Story

The Commonwealth of Oceana unfolds not as a character-driven narrative, but as the systematic creation and demonstration of an ideal constitutional republic. The treatise begins with an examination of political theory, dividing government into the empire of laws versus the empire of men. Harrington traces historical shifts in power, arguing that sovereignty inherently rests upon the balance of property. Analyzing the decline of feudalism in England, he demonstrates how the division of land among the middle classes broke the dominance of the nobility, making a monarchy unsustainable and a commonwealth necessary.

To illustrate how a state should be properly constituted, Harrington introduces the fictional realm of Oceana, a thinly veiled stand-in for England. Following a period of civil conflict, the sole legislator Olphaus Megaletor takes up the task of designing a permanent republic. Megaletor convenes a council to establish fundamental statutes aimed at preventing corruption, tyranny, and oligarchy. Central to this new order is the Agrarian Law, which caps annual land ownership at £2,000 to ensure that land—and thus power—remains widely distributed among thousands of citizens rather than concentrated in a few hands.

The text then details the specific mechanisms of governance across thirty orders. Harrington lays out a bicameral legislature comprising a Senate, which debates policies, and a larger assembly called the Prerogative Tribe, which votes on proposals without engaging in debate. To maintain dynamic civic engagement and prevent entrenched ruling classes, the state enforces regular rotation of public officials. Harrington spends significant space describing the mechanics of elections, specifying precise procedures for drawing lots and using silver and gold balls for secret balloting.

Beyond civil government, the system integrates religious, judicial, and military structures. University-trained scholars provide religious guidance under civil supervision, while military service is organized through local tribes, dividing citizens into active youth and defensive elders. Spoil from external conflicts is methodically distributed between the state treasury and the troops. In its concluding sections, Megaletor presents an epitome of the entire commonwealth to his council and army, securing popular assent through organized votes. Once the system is fully enacted and stabilized, the founding army is disbanded, leaving Oceana as an expanding, self-sustaining republic built to endure.

How It Unfolds

The foundation of property Harrington establishes that political authority follows land ownership, arguing that an equal distribution of property creates an enduring empire of laws rather than tyrants.

The rise of Olphaus Megaletor Following civil war, the noble lawgiver Megaletor assumes the duty of crafting a constitutional blueprint for the island republic of Oceana.

The agrarian limits The commonwealth institutes the Agrarian Law, restricting individual land holdings to £2,000 per year to keep property and power balanced among thousands of citizens.

The machinery of the ballot An intricate system of elections is enacted, using urns, colored balls, and strict rotation to guarantee impartial selections without factional bribery.

The division of legislative power Governance is split between a Senate that proposes and debates laws and a popular assembly that decides outcomes without debate, preserving order.

The civic army and final adoption Military forces are organized by local tribes into youth and elders, and after the assembly ratifies the complete constitution, the temporary standing army disbands.

The People

Olphaus Megaletor Derived from a noble family, Megaletor serves as the sole legislator and Lord Archon of Oceana. He seeks to build a stable, balanced commonwealth out of civil war. Facing opposition from those who distrust systematic planning, he successfully establishes thirty orders of government and relinquishes absolute power once the republic stands on its own.

Lord Epimonus A member of the constitutional council, Lord Epimonus acts as a skeptical, humorous critic of Megaletor's elaborate proposals. He questions the practicality of complex voting machines and foreign political models, but his lively objections allow Megaletor to refine and clarify the state’s mechanisms.

The Senate Composed of elected elders, the Senate functions as the intellectual engine of Oceana. It desires thorough debate and legislative wisdom, constrained by the requirement that it cannot pass laws directly, but must submit all proposals to the broader populace.

The Prerogative Tribe Representing the collective citizenry, this body holds ultimate legislative and judicial authority. It seeks to protect popular liberty against aristocratic overreach, using secret ballots to enact laws proposed by the Senate without falling into chaotic public debate.

In Its Own Voice

"Now government is no other than the soul of a nation or city: wherefore that which was reason in the debate of a commonwealth being brought forth by the result, must be virtue; and forasmuch as the soul of a city or nation is the sovereign power, her virtue must be law."

Harrington defines the fundamental nature of political legitimacy, connecting human reason to the rule of law within a republic.

"A people planted upon an equal agrarian, and holding to it, if they part with their liberty, must do it upon good-will, and make but a bad title of their bounty."

The text emphasizes that a population maintaining equal distribution of land inherently safeguards its own freedom.

"There is a greater light than the sun, but it does not extinguish the sun, nor does any light of God’s giving extinguish that of nature, but increase and sanctify it."

Harrington defends intellectual study and human reason within the commonwealth's religious and academic institutions.

What It's Really About

The Commonwealth of Oceana is fundamentally an investigation into the material roots of political power. Harrington argues that constitutions are not merely abstract agreements, but direct reflections of underlying economic reality. If land belongs to a single monarch, the government becomes an absolute monarchy; if it belongs to a nobility, an aristocracy; and if it is shared broadly among the populace, a republic becomes inevitable. Beneath its legislative instructions, the book wrestles with how to keep a free society from decaying into oligarchy. Through mandatory rotation of offices, secret voting, and strict limits on property accumulation, Harrington attempts to design an institutional machine so perfectly balanced that human passion and greed can never subvert public virtue.

Why Read It Today

The Commonwealth of Oceana offers a fascinating window into seventeenth-century political thought, standing alongside the works of Thomas Hobbes and John Locke as a cornerstone of modern republican theory. Readers interested in constitutional design, political economics, and the history of democratic institutions will find Harrington’s insights remarkably prescient. His ideas directly influenced the founding fathers of the United States, particularly regarding the separation of powers, agrarian policy, and the secret ballot.

Reading the book requires patience. The prose reflects the dense, formal style of early modern political treatises, heavy with classical references to Rome, Lacedaemon, and ancient Israel. Harrington frequently interrupts his political arguments with lengthy procedural orders, exact calculations, and mock parliamentary debates. Yet despite its technical complexity and period-specific language, the text carries an intellectual vigor. It remains a compelling blueprint of an author attempting to solve the problem of political instability through structural design, offering a memorable portrait of how property, law, and liberty intersect.
