Key terms

Italian Renaissance14th-16th c. revival of classical (Greek/Roman) art and literature. Characterized by humanism, secularism, and individualism (e.g., Machiavelli, Michelangelo).
Peace of Westphalia (1648)Ended the Thirty Years' War. Marked the end of major religious wars in Europe and established the modern concept of state sovereignty and balance of power.
MercantilismThe theory that national wealth is a fixed stock of bullion, so states should maximize exports, minimize imports and hold colonies as captive markets. The economic logic behind the colonial system.
Glorious Revolution (1688)Bloodless overthrow of James II in England. William and Mary accepted the English Bill of Rights, firmly establishing a constitutional monarchy.
Scientific RevolutionThe seventeenth-century shift to explaining nature through observation, mathematics and experiment rather than authority. Its deepest change is in method — what counts as proof.
Enlightened absolutismRule by monarchs such as Frederick the Great, Catherine the Great, and Joseph II who adopted legal codification, toleration, and education reform. Significance: shows Enlightenment ideas being used to strengthen state efficiency and revenue while serfdom and noble privilege were preserved or extended.
French Revolution (1789)Driven by Enlightenment ideas, famine, and financial crisis. Shifted from moderate constitutionalism to radical republicanism (Reign of Terror) to Napoleon's empire.
Congress of Vienna (1815)Conservative peace settlement after Napoleon. Led by Metternich, it sought to restore the balance of power and suppress liberalism and nationalism.
Industrial Revolution (First)Began in Britain (late 18th c.) fueled by coal and iron. Mechanized textiles and transportation, creating a new urban working class (proletariat) and bourgeois class.
Social Darwinism19th c. misapplication of evolutionary theory to human societies ("survival of the fittest"). Used to justify imperialism, racism, and extreme capitalism.
RealpolitikPolitics conducted on calculation of power and interest rather than ideology or sentiment. Bismarck and Cavour are the exemplars, and it marks the shift after 1848.
Treaty of Versailles (1919)Ended WWI. Harshly punished Germany (Article 231 war guilt, reparations, demilitarization), creating economic and political instability that fueled the rise of Fascism.
Civic humanismRenaissance conviction that classical learning should prepare citizens for active political life, exemplified by Leonardo Bruni in Florence. Significance: shifted elite education from theology toward rhetoric, history, and ethics, and supplied the intellectual self-image of republican Italian city-states.
Printing press (Gutenberg, c. 1450)Movable metal type applied to European book production. Significance: cut the cost of texts dramatically, standardized vernaculars, made Luther’s pamphlet war possible, and allowed scientific and Enlightenment ideas to circulate faster than censors could suppress them.
Christian humanism (Erasmus)Application of humanist philological method to scripture, notably Erasmus’s 1516 Greek New Testament and his satire In Praise of Folly. Significance: exposed errors in the Vulgate and mocked clerical abuse, preparing the ground for reform — hence the saying that Erasmus laid the egg Luther hatched.
Ninety-Five Theses (1517) and justification by faithLuther’s attack on indulgences, grounded in the claim that salvation comes through faith alone by scripture alone. Significance: denied the sacramental and financial machinery of papal authority, and split Western Christendom permanently.
Calvinism and predestinationCalvin’s teaching in the Institutes that God has eternally elected the saved, developed in a disciplined theocratic Geneva. Significance: produced the most militant and internationally mobile branch of Protestantism, spreading to France, the Netherlands, Scotland, and England.
Council of Trent (1545–1563)Catholic council that reaffirmed tradition alongside scripture, transubstantiation, and the seven sacraments while ending the sale of offices and mandating seminaries. Significance: made compromise with Protestantism impossible while genuinely reforming clerical practice.
Peace of Augsburg (1555)Settlement allowing each German prince to choose Lutheranism or Catholicism for his territory — cuius regio, eius religio. Significance: legitimized religious division as a matter of princely sovereignty, but by excluding Calvinism it left the grievance that helped ignite the Thirty Years’ War.
Edict of Nantes (1598) and its revocation (1685)Henry IV’s grant of limited religious and military rights to Huguenots, revoked by Louis XIV. Significance: the grant ended the French Wars of Religion by subordinating confession to state stability; the revocation exiled perhaps 200,000 skilled Huguenots and showed absolutism demanding uniformity.
Thirty Years’ War and the Peace of Westphalia (1648)Conflict beginning in Bohemia that devastated the German lands and killed perhaps a third of their population, ended by a settlement recognizing Calvinism and state sovereignty. Significance: closed the era of European wars of religion and established the sovereign-state framework of international politics.
Commercial Revolution and mercantilismGrowth of joint-stock companies, banking, and state-directed trade policy aimed at accumulating bullion. Significance: financed exploration and colonization, tied state power to commercial monopoly, and provoked the free-trade critique later formulated by Adam Smith in 1776.
Versailles and French absolutismLouis XIV’s palace and court system, paired with intendants in the provinces and Colbert’s mercantilist finance. Significance: neutralized the nobility by making status depend on royal favor, and became the model of absolute monarchy that other rulers imitated architecturally and politically.
English Bill of Rights (1689)Statute conditioning the reign of William and Mary on parliamentary control of taxation, of peacetime standing armies, and of the succession. Significance: settled the seventeenth-century constitutional conflict in Parliament’s favor and created the model of limited constitutional monarchy.
