The cultural and artistic events of 15th-century Italy are collectively referred to as the Quattrocento (Italian pronunciation: [ˌkwattroˈtʃɛnto]) from the Italian for the number 400, in turn from millequattrocento, 1400, the year that ended the 14th century. Quattrocento encompasses the artistic styles of the late Middle Ages (most notably International Gothic) and the early Renaissance.
After the decline of the Western Roman Empire in 476, economic disorder and disruption of trade spread across Europe. This was the beginning of the Early Middle Ages, which lasted roughly until the 11th century, when trade picked up, population began to expand and the papacy regained its authority.
In the late Middle Ages, the political structure of the European continent slowly evolved from small, highly unstable fiefdoms into larger nation states ruled by monarchies, thereby providing greater stability. In Italy, urban centers arose that were populated by merchant and trade classes, who were able to defend themselves. Money replaced land as the medium of exchange, and increasing numbers of serfs became freedmen. The changes in Medieval Italy and the decline of feudalism paved the way for social, cultural, and economic changes.
The Quattrocento is viewed as the transition from the Medieval period to the age of the Renaissance, principally in the cities of Rome, Florence, Milan, Venice and Naples.
