Many small inventions have changed culture but I will only list two or it would take forever.
The Stirrup: The stirrup is a rest for the foot of the rider, possibly the rider of a horse. The stirrup is useful for communications of the rider and horse making it easier to ride and to ride into battle. The stirrup is a long strip of leather with a foot holder to make riding easier and making knights be able to have heavier weapons.The stirrup changed culture by making it easier to ride the horse thus making the person able to have heavy weapons while riding.
Heavy Plow: The heavy plow has a knife like cutter called a foreshare. What the heavy plow does is it breaks the top soil and gets the rich and fertile soil up to plant crops. It changed culture by boosting population because of more food.
Thank you for reading my paragraph on how small inventions changed culture.
