My revolution is the invention of gunpowder and the effect it had on warfare. Long-term, gunpowder was a positive invention and led to many modern creations. Without it we would not have guns, fireworks, missiles, and even some vehicles that are powered by gunpowder. The most important moment in this revolution was when gunpowder was first used to launch a projectile out of a firearm in 1364. Unfortunately, some people use gunpowder for corrupt reasons like personal gain or anger.
