What invention advanced the life in the Middle Ages the most?
There were a lot of inventions in the Middle Ages that profoundly influenced the lives of people. The one most people might pick as the most important is the printing press. There were others we might look at, however, and one of my favorites is the chimney, which was invented in the 11th century and made real fireplaces possible for the first time in history. Prior to that invention, the fire was on a hearth or brazier, in the middle of the floor. The horse collar is another that increased agricultural production; it and other agricultural inventions made the population of Europe much greater at the end of the Middle Ages than it had ever been during the Roman Empire.
