Renaissance, Reformation, and Scientific revolution

Renaissance

A cultural movement that began in the Italian city-states and later spread

across Europe. The word means “rebirth,” referring especially to renewed interest in the

literature, philosophy, art, and culture of ancient Greece and Rome.

Humanism

An intellectual movement centered on the study of language, literature, history,

rhetoric, philosophy, and classical texts. Humanists believed education could develop human abilities and improve individuals and society. Humanism did not mean rejection of Christianity.

Classical Antiquity

The civilizations of ancient Greece and Rome. Renaissance scholars and

artists studied classical literature, philosophy, architecture, sculpture, and political thought.

City-State

An independent political state consisting of a city and the surrounding territory.

Renaissance Italy contained competing city-states such as Florence, Venice, Milan, and Genoa.

Patronage

Financial support given to artists, writers, architects, or scholars. Wealthy families, governments, guilds, and churches commissioned works of art and scholarship. The Medici family was especially famous for patronage in Florence.

Naturalism

An artistic effort to represent people, bodies, movement, light, emotion, and physical space in ways that resemble careful observation of the natural world.

Linear Perspective

A technique for creating the illusion of three-dimensional depth on a flat surface. Parallel lines appear to converge toward a vanishing point.

Vernacular

The ordinary language spoken by people in a particular region, such as Italian, English, French, or German, rather than Latin. Printing increasingly made works written in vernacular languages available to wider audiences

Northern Renaissance

The Renaissance as it developed in northern Europe. Northern humanists and artists adopted ideas from Italy while often placing greater emphasis on Christianity, moral reform, detailed realism, and ordinary life.

Printing Press

Gutenberg's system of movable metal type made it possible to produce books much more quickly and cheaply than copying them by hand. Printing helped spread Renaissance, Reformation, and scientific ideas across Europe

Protestant Reformation

The sixteenth-century movement that challenged the authority and teachings of the Catholic Church and resulted in the creation of multiple Protestant churches.

Indulgence

A remission of temporal punishment for sins that had already been forgiven. Controversial preaching and selling of indulgences helped provoke Luther's criticism of Church practices.

Sola Scriptura

“Scripture alone.” The Protestant principle that the Bible is the highest authority for Christian belief rather than the pope or Church tradition.

Sola Fide

“Faith alone.” Luther's teaching that justification—being made right with God—comes through faith rather than being earned through good works.

Sect

A distinct religious group within a larger religious tradition. The Reformation produced

Lutheran, Calvinist, Anabaptist, Anglican, and other Protestant communities.

Lutheranism

The Protestant tradition based on the teachings of Martin Luther. It emphasized justification by faith and the authority of Scripture while rejecting papal supremacy.

Predestination

The doctrine, strongly associated with John Calvin, that God has already determined who will ultimately be saved.

Calvinism

The Protestant tradition associated with John Calvin. It emphasized God's sovereignty, predestination, disciplined Christian living, and a more thorough reform of worship than Luther generally advocated.

Act of Supremacy

The 1534 law recognizing Henry VIII as Supreme Head of the Church of England. It formally rejected papal authority over the English Church.

Church of England

The English national church that emerged from Henry VIII's break with Rome. Under Henry, it remained Catholic in many doctrines even though it rejected papal authority.

Catholic Reformation

The movement of Catholic renewal during the sixteenth century. Catholics responded to Protestant challenges while also reforming problems within their own Church.

Council of Trent

A major Catholic council meeting between 1545 and 1563. It reaffirmed Catholic teachings while improving clerical education, discipline, and Church administration.

Jesuits

Members of the Society of Jesus, founded by Ignatius of Loyola. They became influential teachers, missionaries, scholars, and defenders of Catholicism.

Heresy

A belief or teaching judged to contradict the official doctrine of a church.

Inquisition

Church institutions that investigated suspected heresy. Inquisitions could use interrogation, imprisonment, censorship, and cooperation with secular governments in punishing convicted heretics. It is inaccurate to define the Inquisition simply as “secret testimony, torture, and execution.”

Religious Persecution

Punishment or discrimination against people because of their religious beliefs. Catholics, Protestants, and radical reformers all experienced persecution in sixteenth-century Europe.

Ghetto

A district in which a particular group was required or pressured to live separately. In 1516 Venice confined its Jewish population to a designated district that became known as the ghetto.

Geocentrism

The model in which Earth remains stationary at the center of the universe. The system was strongly associated with the ancient astronomer Ptolemy.

Heliocentrism

The model in which Earth and the other planets orbit the Sun. Copernicus proposed the major Renaissance-era version of this model.

Scientific Method

A broad approach to studying nature through systematic observation, hypotheses, experimentation, measurement, reasoning, and revision of explanations according to evidence.

Empiricism

The idea that knowledge should be based substantially on observation and experience.

Hypothesis

A proposed explanation that can be tested against evidence.

Induction

Reasoning from specific observations toward broader conclusions. Francis Bacon strongly emphasized this approach

Deduction

Reasoning from general principles toward particular conclusions. René Descartes placed especially strong emphasis on reason and deduction

Gravity

The force of attraction between masses. Newton argued that the same force governing falling objects on Earth also governs the motions of planets and moons.

Calculus

A form of mathematics developed independently by Isaac Newton and Gottfried Wilhelm Leibniz for analyzing continuous change and motion.

Petrarch

An Italian poet and scholar often regarded as an early humanist. He searched for and studied ancient Latin texts and helped inspire renewed interest in classical literature

Giovanni Boccaccio

Italian author of the Decameron. His stories examine love, social class, wealth, family, religion, intelligence, and human behavior.

Medici Family

A wealthy Florentine banking family that gained enormous political influence and became major patrons of Renaissance art and scholarship

Leonardo da Vinci

Renaissance artist, engineer, and investigator of nature. He painted works including the Mona Lisa and The Last Supper and studied subjects such as anatomy and mechanics.

Michelangelo

Renaissance sculptor, painter, architect, and poet. Major works include David and the ceiling of the Sistine Chapel.

Albrecht Dürer

German Northern Renaissance artist especially famous for detailed paintings, woodcuts, and engravings. His widely reproduced prints helped circulate Renaissance artistic ideas.

Niccolò Machiavelli

Florentine diplomat and political thinker who wrote The Prince. He analyzed how rulers actually acquire and preserve political power and argued that circumstances may sometimes require rulers to use deception or force. It is too simplistic to reduce his argument to “do anything necessary” or “the ends justify the means.”

Erasmus

Dutch Christian humanist, scholar, and Catholic priest. He studied Greek and Latin texts, produced an important Greek edition of the New Testament, criticized corruption and hypocrisy, and called for Christian reform.

Thomas More

English humanist, statesman, and author of Utopia. Henry VIII had him executed after More refused to recognize the king's supremacy over the English Church

Johannes Gutenberg

German craftsman who developed an effective European system of printing using movable metal type. His technology dramatically increased the speed and scale at which written material could circulate.

Felix Platter

Swiss Renaissance physician and diarist who studied medicine at Montpellier. His life illustrates Renaissance interests in education, anatomy, travel, observation, collecting, and the natural world.

Martin Luther

German monk and theologian whose criticism of indulgences and Catholic authority helped launch the Protestant Reformation. He emphasized justification by faith, the authority of Scripture, and the spiritual equality of Christians through baptism.

John Calvin

French Protestant theologian who became a leading reformer in Geneva. He emphasized God's sovereignty, predestination, and strict religious discipline.

Henry VIII

King of England who broke with papal authority when the pope would not grant the annulment he sought from Catherine of Aragon. Henry made himself head of the English Church but retained many traditional Catholic beliefs.

Catherine of Aragon

Henry VIII's first wife and the mother of Mary Tudor. Henry's effortto annul their marriage became the immediate cause of England's break with Rome.

Anne Boleyn

Henry VIII's second wife and Elizabeth I's mother. Her marriage to Henry was closely connected to his break with Rome. She was executed in 1536 after being convicted on charges of adultery and treason that historians generally regard as highly dubious.

Thomas Cromwell

Henry VIII's powerful minister who played a major role in carrying out the break with Rome and the dissolution of the monasteries. He was eventually executed after losing Henry's favor.

Mary Tudor (Mary I)

Daughter of Henry VIII and Catherine of Aragon and the first woman to rule England in her own right with full royal authority. A committed Catholic, she attempted to reverse Protestant reforms and restored ties to Rome. About 300 Protestants were executed for heresy during her reign.

Elizabeth I

Daughter of Henry VIII and Anne Boleyn. She became queen after Mary's death in 1558 and established a Protestant religious settlement intended to create greater political and religious stability.

Ignatius of Loyola

Spanish former soldier who founded the Society of Jesus. The Jesuits emphasized education, discipline, missionary activity, and loyalty to the Catholic Church

Nicolaus Copernicus

Polish astronomer who proposed a heliocentric system in which Earth and the other planets orbit the Sun.

Tycho Brahe

Danish astronomer who constructed highly precise astronomical instruments and collected extraordinarily accurate observations. His data later allowed Kepler to discover the laws of planetary motion.

Johannes Kepler

German astronomer and mathematician who used Tycho's data to show that planets move around the Sun in elliptical rather than perfectly circular orbits. He formulated three laws of planetary motion.

Galileo Galilei

Italian mathematician and astronomer who improved the telescope and used it to study the heavens. Among other discoveries, he observed mountains and craters on the Moon and four moons orbiting Jupiter. His work challenged the traditional Aristotelian and Ptolemaic picture of the universe.

Francis Bacon

English philosopher who argued for systematic observation and experimentation and emphasized inductive reasoning as a method for investigating nature.

René Descartes

French philosopher and mathematician who emphasized systematic doubt, logical reasoning, deduction, and mathematics as paths toward reliable knowledge.

Robert Boyle

English scientist whose controlled experiments on gases helped demonstrate the importance of measurement, experimentation, and reproducibility.

Isaac Newton

English mathematician and physicist who formulated the laws of motion and universal gravitation. His work showed that the same mathematical laws govern motion on Earth and in the heavens. He also independently developed calculus.
