The intellectual transformation of the Renaissance is viewed as a bridge between the Middle Ages and the Modern era. Europeans would later begin an era of world discovery. Combined with the influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning.

Their discoveries strengthened the economy and power of European nations.
Question: What effect didn't the discoveries of Columbus and da Gama have on European nations?
