Chinese chemists mixed together a combination of saltpeter, charcoal and potassium nitrate that would form the explosive and powerful powder called gunpowder. Gunpowder was soon used as a powerful additive in explosive weaponry. This was brought to Europe through the silk trade route in the 13th century. This brought a totally new concept in warfare that is still widely used in armies and terrorism today. Guns, muskets and cannons could be used to conquer fortresses and the new world. Without the use of gunpowder our world would be completely different today. So, take away gunpowder and what would have changed in history. Fighters would only have swords, spears and arrows. This would have made taking over lands and empires next to impossible.
