Renaissance
Many argue that the ideas characterizing the Renaissance had their origin in late 13th-century Florence, in particular with the writings of Dante Alighieri (1265–1321) and Petrarch (1304–1374), as well as the paintings of Giotto di Bondone (1267–1337). Some writers date the Renaissance quite precisely; one proposed starting point is 1401, when the rival geniuses Lorenzo Ghiberti and Filippo Brunelleschi competed for the contract to build the bronze doors for the Baptistery of the Florence Cathedral (Ghiberti won). Others see more general competition between artists and polymaths such as Brunelleschi, Ghiberti, Donatello, and Masaccio for artistic commissions as sparking the creativity of the Renaissance. Yet it remains much debated why the Renaissance began in Italy, and why it began when it did. Accordingly, several theories have been put forward to explain its origins.
Early modern Europe
Early modern Europe is the period of European history between the end of the Middle Ages and the beginning of the Industrial Revolution, roughly the late 15th century to the late 18th century. Historians variously mark the beginning of the early modern period with the invention of moveable type printing in the 1450s, the Fall of Constantinople in 1453, the end of the Wars of the Roses in 1487, the beginning of the High Renaissance in Italy in the 1490s, the end of the Reconquista and subsequent voyages of Christopher Columbus to the Americas in 1492, or the start of the Protestant Reformation in 1517. The precise dates of its end point also vary and are usually linked with either the start of the French Revolution in 1789 or with the more vaguely defined beginning of the Industrial Revolution in late 18th century England.
