Liberalism is not a single philosophy but an evolving, often contradictory, set of ideas.

In short: Liberalism emerged as a radical challenge to the divine right of kings, asserting that individuals possess inalienable rights. Yet, this same tradition has historically accommodated slavery and exclusion. It remains an amorphous, shifting project that balances the protection of individual liberty against the potential tyranny of the state and majority.

Liberalism lacks a single origin point, but the 1688 Glorious Revolution in England serves as a pivotal forerunner. When James II fled, Parliament constrained the monarchy, establishing a new relationship that enshrined political rights. Thinkers like John Locke, writing in 1689, argued that government legitimacy rests solely on the consent of the governed, a radical departure from the belief that rulers held divine authority. Locke’s social contract theory posited that government exists to protect natural rights to life, liberty, and property.

The 18th century saw these ideas codified into blueprints for governance. Montesquieu proposed a separation of powers into legislative, executive, and judicial branches, directly influencing the American founders. The American Revolution in 1775-83 established a republic under a written constitution, though it remained incomplete by excluding women, the poor, and enslaved people. Meanwhile, the French Revolution of 1789-99 offered a more radical, universal vision of rights, yet descended into the Reign of Terror, illustrating the danger of movements convinced of their own absolute righteousness.

Modern liberalism has evolved significantly since its classical roots. While early thinkers like Adam Smith championed free markets and limited government, 20th-century developments shifted the focus. Most modern liberals argue that government must actively remove obstacles to freedom—such as poverty and discrimination—rather than merely protecting individuals from harm. This has led to the development of the welfare state, particularly in the United States, while European liberalism often retains a stronger emphasis on laissez-faire economics.

Ultimately, liberalism is defined by its commitment to adversariality—the belief that competition and dialogue are the best ways to resolve conflict. It remains a precarious project, constantly negotiating the tension between democracy, which empowers majorities, and the liberal imperative to protect the rights of unpopular minorities. It is a doctrine sensitive to time and circumstance, forever changing to meet the challenges of each generation.
