The transition from the medieval to the modern world was marked by a cultural revival and a dramatic reshaping of global connections. The Renaissance (14th–17th century) began in Italy as an intellectual movement emphasizing humanism, art, science, and classical learning. Figures like Leonardo da Vinci (1452–1519), a true polymath, produced masterpieces such as the Mona Lisa and The Last Supper while also making groundbreaking studies in anatomy, engineering, and flight. At the same time, the Ottoman Empire (c. 1299–1922) emerged as a powerful Islamic state spanning Southeast Europe, Western Asia, and North Africa, controlling key trade routes and reaching its peak under Suleiman the Magnificent as a major world power.
Religious transformation swept through Europe with the Protestant Reformation, which began in 1517 when Martin Luther (1483–1546), a German monk and theologian, published his 95 Theses criticizing the Catholic Church, especially the sale of indulgences. Luther's ideas about salvation through faith alone and biblical authority led to the creation of Protestant denominations and reshaped European politics and society for centuries. Simultaneously, the Age of Exploration (15th–17th century) saw European powers such as Portugal, Spain, England, and France explore and colonize territories across the Americas, Africa, and Asia, reshaping global trade, demographics, and power structures.
The voyages of Christopher Columbus (1451–1506), sponsored by Spain in 1492, initiated sustained European contact with the Americas, even though indigenous peoples had lived there for millennia. The resulting Columbian Exchange transferred plants, animals, diseases, and culture between the Old and New Worlds, introducing crops like potatoes and tomatoes to Europe while devastating indigenous populations through diseases like smallpox. To manage this new landscape, the Treaty of Tordesillas (1494) divided newly discovered lands outside Europe between Spain and Portugal along a meridian 370 leagues west of the Cape Verde Islands, giving Portugal claim to Brazil and Spain claim to most of the Americas. Together, the Renaissance, Reformation, and Age of Exploration shattered medieval worldviews and laid the foundations of the modern global era.
