The Renaissance was a European period of history and cultural movement taking place at the end of the Late Middle Ages and the beginning of the early modern era. It is variously defined as lasting from the 14th century to the 17th or, more narrowly, as covering only the 15th and 16th centuries. It was characterized by the European rediscovery and revival of the literary, philosophical, and artistic achievements of classical antiquity. Associated with great change in art, architecture, politics, literature, exploration and technology, the Renaissance was first centered in the Republic of Florence, then spread to the rest of Italy and later throughout Europe.
