Answer: Banking
Explanation: In addition to contributing to the revival and development of classical Greek art, philosophy and humanism, the Renaissance also influenced the changing climate of social life and social movements. First of all, it is the promotion of trade and trade routes, the flow of ideas, and the development of banking. During the Renaissance, when the traditional teaching of the Church was abandoned, the ideas of humanism and naturism began to spread, and the whole climate of social flows created a new layer of businessmen, merchants and bankers. Thus, many very influential banks, owned by wealthy families, were established in the Italian city-states.
