Two things that were brought into Europe and played a significant role in creating a bustling economy, prosperous cities, and new classes of people were trade and the Renaissance.

1. Trade: The expansion of trade routes and the discovery of new trade routes, such as the Silk Road to the East and the exploration of new sea routes, brought an influx of goods, resources, and wealth into Europe. The trade of luxury goods, spices, and commodities such as silk, porcelain, and precious metals increased tremendously. This led to the rise of prosperous cities and the growth of a merchant class, as trade hubs and commercial centers developed to facilitate the exchange of goods. These cities became economic powerhouses, contributing to the emergence of a thriving economy.

2. The Renaissance: The Renaissance was a period of intellectual and cultural growth that occurred mainly in the 14th to 17th centuries. It brought about a renewed interest in classical literature, arts, sciences, and humanism. The Renaissance thinkers and artists were inspired by the knowledge and ideas of ancient Greece and Rome that were rediscovered during this time. This revival of learning and creativity fueled innovation and encouraged exploration, which led to advancements in various fields, including art, literature, architecture, and science. The patronage of wealthy individuals such as the Medici family in Florence helped support artists and scholars, contributing to the flourishing of artistic and intellectual endeavors. The Renaissance brought about new forms of expression and led to the rise of new classes, including patrons, scholars, artists, and artisans, who contributed to the growing economy and the cultural development of Europe.
