The main people affected by gunpowder are the soldiers out fighting in the wars all over the world, they have to work harder to win the battle because of new weapons. There are very few people who haven't been affected in one way shape or form by gunpowder or a gunpowder product. The invention of gunpowder is probably a Chinese success because they created it and changed many things on Earth for good and bad. The Chinese Alchemists failed in what they set out to do, create gold, but they also accidentally made gunpowder and changed the world.
