The European Renaissance began in Tuscany (Central Italy), and centered in the cities of Florence and Siena. It later spread to Venice, where the remains of ancient Greek culture were brought together, providing humanist scholars with new texts. The Renaissance later had a significant effect on Rome, which was ornamented with some structures in the new all'antico mode, then was largely rebuilt by humanist sixteenth-century popes. The Italian Renaissance peaked in the mid-16th century as foreign invasions plunged the region into the turmoil of the Italian Wars. However, the ideas and ideals of the Renaissance endured and even spread into the rest of Europe, setting off the Northern Renaissance, and the English Renaissance.
