There are many ways in which the Renaissance changed Europe. I will name a few ways.
First, the Renaissance, which started in the fifteen century in Florence, gave many Europeans confidence that they could surpass the classical world, which loomed as a giant of achievement. The Renaissance produced a flowering of intellectual pursuits and the arts, which still claim greatness today.
Second, the Renaissance also enabled people to question the traditions of the Medieval world. In this sense, they were set free from tradition to explore. In connection to this point, the Renaissance gave the intellectual tools for people to break from the Catholic church as well. This can be seen most powerfully in the Protestant Reformation. According to many scholars, the Protestant Reformation was an direct outflow of the Renaissance. For example, John Calvin's first written work was on the Roman philosopher Seneca.
In conclusion, the Renaissance played a powerful role in various areas.
