Weell, there's a reason the Renaissance is called "renaissance" and not something else.
Go read the Book of the Games from the 1200's and now you'll learn something. The Middle ages were centuries wide. The last centuries had nothing to do, say, with the 5th century.
The Renaissance is really the tail end of the Middle Ages historically, and the name is a bit of propaganda, just like "Enlightenment".
People flatter themselves.
That reason is self-hype. The Renaissance was dreadful in comparison to the Late Middle Ages and the Early Modern Period in much of Europe.
