during what dynasty did the chinese make explosives
History of gunpowder Gunpowder is the first physical explosive and propellant. Before its invention, many incendiary and burning devices had been used, including Greek fire. The invention of gunpowder is attributed to experimentation in Chinese alchemy by Taoists in the pursuit of immortality, and is popularly listed as one of the "Four Great Inventions" of China. It was invented during the late Tang dynasty (9th century) but the earliest record of a written formula appeared in the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout the Old World possibly as a result of the Mongol conquests during the 13th century, with the earliest written formula for it outside of China contained within the Opus Majus, a 1267 treatise by the English friar Roger Bacon. It was employed in warfare to some effect from at least the 12th century in weapons such as fire arrows, bombs, and the fire lance before the appearance of the gun. While the fire lance was eventually supplanted by the gun, other gunpowder weapons such as rockets continued to see use in China, Korea, India, and eventually Europe. Bombs too never ceased to develop and continued to progress into the modern day as grenades, mines, and other explosive implements. Gunpowder has also been used for non-military purposes such as fireworks for entertainment, or in explosives for mining and tunneling.
Names of China The names of China include the many contemporary and historical appellations given in various languages for the East Asian country known as Zhongguo (中國/中国) in its official language. China, the name in English for the country, was derived from Portuguese in the 16th century, and became popular in the mid 19th century.[1] It is believed to be a borrowing from Middle Persian, and some have traced it further back to Sanskrit. It is also generally thought that the ultimate source of the name China is the Chinese word "Qin" (Chinese: 秦), the name of the dynasty that unified China but also existed as a state for many centuries prior. There are however other alternative suggestions for the origin of the word.
