2. Italy was one of the most developed countries in Europe at that time, with a long cultural tradition. Many Greek and Roman cultural heritages, including documents and cultural relics, have been preserved in Italy. It was a fashion and trend in Italy at that time to sort out and study these historical heritages. Administrative agencies and wealthy businessmen in various cities spared no expense in collecting ancient books and other documents and establishing libraries. At the same time, they are also competing to recruit talented people to carry out relevant research.
3. Renaissance has a solid mass base in Italy, which is the local citizen class. Medieval civilization is a Christian civilization, which advocates the concepts of keeping a low profile, tolerance and humility, and indifference to wealth. With the germination of capitalism, a group of citizens left the land to make a living by commerce and handicrafts appeared in Italy. They pay attention to real life, worship wealth and long for individual freedom and liberation, which has gradually drifted away from the moral norms formed in medieval agricultural society. The change of social environment and people's values calls for a new culture, and the humanistic thought advocated by the Renaissance just meets the requirements of the civil class, so it has a broader social foundation and development space.
