genghis you have to ask yourself what was the effect of the revival of classical antiquity? This is the underlying philosophical phenomenon of the renaissance, which is why literally ANY "Crash Course World History" will tell you that the Renaissance was the actual cause behind the rise in humanism, the scientific revolution, and the beginnings of the Protestant revolution (although I admit that these are more indirect effects).
Here is a list of direct effects of the Renaissance (these are not by-the-by things and are all vitally important so this era should not be thrown to the side as just useless art): http://www.shsu.edu/~his_ncp/Renn.html
1. New Conceptions of Life and the World
2. Restored the Broken Unity of History
3. Aided the Development of Vernacular Literature
4. Called into Existence the Science of Archaeology and Historical Criticism
5. Gave an impulse to Religious Reform
