Gunpowder a potion for immortality
Gunpowder was supposed to be a potion for unlimited life and ended up being a potion for death that is still used today.
Ancient Chinese alchemists were trying to find a potion for immortality and they ended up making gunpowder. When the Chinese found out that it exploded they used it for fire works. After a few hundred years they started using it in war. They first used it at the beginning of a war to try to scare people off before they fought them. The Chinese finally realized that if you explode gunpowder near people they might die so they started using it in war as a kind of explosive. he invention of gunpowder, and the weapons it is used in, forced war to be in different locations. Instead of having a war at a castle you would meet at a field or along the way. Instead of waiting for enemies to arrive, people would both charge and meet some where in between camps. With the invention of gunpowder, castles were less useful because now that they could be blown to bits there was no reason for making something that would just be blown up, so castles became less and less common.
So gunpowder was supposed to be a potion for unlimited life and ended up being a potion for death that is still used today. Gunpowder was one of the most important inventions in warfare. It has also evolved in to many different inventions, which have changed the way of warfare.
