national lines.” This form of international Miltonic republicanism has been influential on later thinkers including 19th-century radicals Karl Marx and Friedrich Engels, according to Warren and other historians. The collapse of the Commonwealth of England in 1660 and the restoration of the monarchy under Charles II discredited republicanism among England's ruling circles. Nevertheless, they welcomed the liberalism, and emphasis on rights, of John Locke, which played a major role in the Glorious Revolution of 1688. Even so, republicanism flourished in the "country" party of the early 18th century (commonwealthmen), which denounced the corruption of the "court" party, producing a political theory that heavily influenced the American colonists. In general, the English ruling classes of the 18th century vehemently opposed republicanism, typified by the attacks on John Wilkes, and especially on the American Revolution and the French Revolution. French and Swiss thought French and Swiss Enlightenment thinkers, such as Voltaire, Baron Charles de Montesquieu and later Jean-Jacques Rousseau, expanded upon and altered the ideas of what an ideal republic should be: some of their new ideas were scarcely traceable to antiquity or the Renaissance thinkers. Concepts they contributed, or heavily elaborated, were social contract, positive law, and mixed government. They also borrowed from, and distinguished republicanism from, the ideas of liberalism that were developing at the same time. Liberalism and republicanism were frequently conflated during this period, because they both opposed absolute monarchy. Modern scholars see them as two distinct streams that both contributed to the democratic ideals of the modern world. An important distinction is that, while republicanism stressed the importance of civic virtue and the common good, liberalism was based on economics and individualism. It is clearest in the matter of private property, which, according to some, can be maintained only under the protection of established positive law. Jules Ferry, Prime Minister of France from 1880 to 1885, followed both these schools of thought. He eventually enacted the Ferry Laws, which he intended to overturn the Falloux Laws by embracing the anti-clerical thinking of the Philosophes. These laws ended the Catholic Church's involvement in many government institutions in late 19th-century France, including schools. The Thirteen British Colonies in North America In recent years a debate has developed over the role of republicanism in the American Revolution and in the British radicalism of the 18th century. For many decades the consensus was that liberalism, especially that of John Locke, was
