When was gunpowder invented?

Gunpowder was invented in the Spring and Autumn Period, but it was mainly used as an alchemist for people's livelihood at that time, not for military use later.

At the end of the Tang dynasty, gunpowder was used in the military, mainly for artillery rockets. The continuous wars in the Song Dynasty promoted the accelerated development of gunpowder weapons, and gunpowder arrows, artillery and other combustible weapons appeared one after another, as well as explosive weapons such as thunderbolt and thunderbolt.

Tubular firearms appeared in the Southern Song Dynasty. In A.D. 1259, a sudden musket was made in Shouchun area. The sudden musket is made of a thick bamboo tube with a "sub-nest" inside. After the powder is ignited, it produces strong gas pressure and shoots at the "sub-nest". The "sub-nest" is an atomic bomb.

There is no exact time for the invention of gunpowder, except that in the Spring and Autumn Period, gunpowder was really used in the Song Dynasty.

China people generally believe that gunpowder is one of the four great inventions in ancient China. There is no such thing as four great inventions of ancient china in western countries, but it is generally believed that gunpowder was first invented and used by China.

It is generally believed that in the Song Dynasty in the 1 1 century, China began to use it as a tool of war, in the form of rockets and trebuchets carrying bombs. The earliest traceable record is 1259, in which a soil warhead was fired with bamboo branches. Most of these rockets are just scary, but they don't actually pose a huge threat.

Engels once spoke highly of China's pioneering role in the invention of gunpowder: "It has been proved beyond doubt that gunpowder was passed from China to Arabs through India, and then from Arabs to Europe together with gunpowder weapons through Spain."
