Renaissance society was very different from feudal society of the middle ages. The Medieval world was built around the nearest manor and most everyday activities had to do with a manor or castle. By the time of the Renaissance, towns in southern Europe had grown greatly in size. The wealthy people who lived in Renaissance society had more spare time and money than in the Middle Ages. This meant they could spend more time studying new ideas and had more money to truly patronize the arts.
The medieval view of the world was a look at the bad side of things: People thought of life as short and full of suffering. There was very little medieval art that didn't have a religious theme, and most art was made by hired artists for a church, to teach people about there faith and encourage them to lead better lives so they could go to heaven.
The middle ages did not, of course, end abruptly. Some people still clung on to the medieval view of the world but slowly this view ended almost completely.
During the Renaissance period people became tired of the world view in the Middle Ages. To them, the feudal period had been a period of inactivity and sluggish growth. Instead, Renaissance people admired the classical age and the great artists and thinkers of ancient Greece and Rome.
Much ancient art, especially sculpture, had been made to celebrate the beauty of human form. Ancient Greek and Roman artists had tried to communicate a sense of beauty in their art. Greek thinkers had developed systems of philosophy that showed people how to improve themselves and their society through there own efforts. In short, the classical society was optimistic, and much better then the views from the Middle Ages. Renaissance artists and thinkers worked hard to bring the classical culture to life again, and to make a new better age.
As towns and cities prospered in northern Europe, new ideas spread there too, often with the help of the newly invented printing press. Renaissance in the north was very different in many ways from that of Italy, but at the base of both was the same deep belief in humans work and effort. The Renaissance was a time of new awakening in Europe. It includes the general loss of power by the church, an increase in literacy and education, and an exploration period.
