Why is the era from 1350 to 1550 in Europe called the Renaissance?

The Renaissance was a period of rebirth.

From 1350 to 1550 in Europe, arts, literature, and sciences flourished. It was a stark contrast to the blatant ignorance of people during the Middle Ages, just one era before. During the Renaissance, people started to seek out knowledge beyond just the information the religious leaders had been spewing them.

Many of the greatest artists we still revere now worked during that time, including Michelangelo and Leonardo da Vinci.
