![]() History of gunpowder - Wikipedia. Earliest known written formula for gunpowder, from the Wujing Zongyao of 1. AD. 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 usually 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 (1. Knowledge of gunpowder spread rapidly throughout the Old World possibly as a result of the Mongol conquests during the 1. China contained within the Opus Majus, a 1. English friar Roger Bacon. It was employed in warfare to some effect from at least the 1. 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. The evolution of guns led to the development of artillery during the 1. Duchy of Burgundy. Firearms came to dominate early modern warfare in Europe by the 1. The gradual improvement of cannons firing heavier rounds for a greater impact against fortifications led to the invention of the star fort and the bastion in the Western world, where traditional city walls and castles were no longer suitable for defense. The use of gunpowder technology also spread throughout the Islamic world and to India, Korea, and Japan. The so- called Gunpowder Empires of the early modern period consisted of the Mughal Empire, Safavid Empire, and Ottoman Empire. The use of gunpowder in warfare during the course of the 1. Gunpowder is often referred to today as "black powder" to distinguish it from the propellant used in contemporary firearms. Chinese beginnings[edit].

Although it is not known precisely by whom gunpowder was invented, most historians agree that gunpowder's origins were in China by virtue of archaeological evidence and historical documents predating others by centuries, even if some professional military historians know little or nothing else about this early history of gunpowder warfare.[2] The very earliest possible reference to gunpowder appeared in 1. AD during the Eastern Han dynasty, when the alchemist. Wei Boyang wrote about a substance with the properties of gunpowder, and described a mixture of three powders that would "fly and dance" violently in his Cantong qi, otherwise known as the Book of the Kinship of Three, a Taoist text on the subject of alchemy.[3][4] Although it is impossible to know if he was actually referring to gunpowder, no other explosive known to scientists is composed of three powders.[3] While it was almost certainly not their intention to create a weapon of war, Taoist alchemists would continue to play a major role in the invention of gunpowder due to their experiments on sulfur and saltpeter in the search for the secrets of eternal life and ways to transmute one material into another.[3] Historian Peter Lorge notes that despite the early association of gunpowder with Taoism, this may be a quirk of historiography, and a result of the better preservation of texts associated with Taoism rather than being a point of interest limited to only Taoists. The Taoist quest for the elixir of life attracted many powerful patrons, one of whom was Emperor Wu of Han, and one of the resulting alchemical experiments involved heating sulfur and saltpeter to transform them.[3]The next possible reference to gunpowder appeared in the year 3. Jin dynasty (2. 65–4. A Taoist philosopher by the name of Ge Hong wrote down the ingredients of gunpowder in his surviving works, collectively known as the Baopuzi ("The Master Who Embraces Simplicity"). The "Inner Chapters" on Taoism contains records of his experiments with heated saltpeter, pine resin, and charcoal among other carbon materials, resulting in explosion, which most historians acknowledge as an early form of gunpowder.[7] In 4. Taoist alchemists had noted that saltpeter, one of the most important ingredients in gunpowder, burns with a purple flame, allowing for practical efforts at purifying the substance. The first confirmed reference to what can be considered gunpowder in China occurred more than three hundred years later during the Tang dynasty, first in a formula contained in the Taishang Guaizu Danjing Mijue in 8. Taoist text known as the Zhenyuan miaodao yaolüe (真元妙道要略). The first formula was a combination of six parts sulfur to six parts saltpeter to one part birthwort herb, and the Taoist text warned against an assortment of dangerous formulas, one of which corresponds with gunpowder: "Some have heated together sulfur, realgar (arsenic disulphide), and saltpeter with honey; smoke [and flames] result, so that their hands and faces have been burnt, and even the whole house burned down." Alchemists called this discovery fire medicine ("huoyao" 火藥), and the term has continued to refer to gunpowder in China into the present day, a reminder of its heritage as a side result in the search for longevity increasing drugs.[9]The earliest surviving chemical formula of gunpowder dates to 1. Wujing Zongyao, also known in English as the Complete Essentials for the Military Classics, which contains a collection of factoids on Chinese weaponry. The Wujing Zongyao served as a repository of antiquated or fanciful weaponry, and this applied to gunpowder as well, which suggests that it had already been weaponized long before the invention of what would today be considered conventional firearms. These numerous types of gunpowder weapons styling various names such as "flying incendiary club for subjugating demons," "caltrop fire ball," "ten- thousand fire flying sand magic bomb," "big bees nest," "burning heaven fierce fire unstoppable bomb," "fire bricks" which released "flying swallows," "flying rats," "fire birds," and "fire oxen" eventually gave way and coalesced into a smaller number of dominant types, notably gunpowder arrows, bombs, and guns. This was probably because some weapons were deemed too onerous or ineffective to deploy.[1. Fire arrows[edit]At this point the formula contained too little saltpeter (about 5. One of the first, if not the first of these weapons was the fire arrow.[1. The first possible reference to the use of fire arrows was by the Southern Wu in 9. Yuzhang, when an officer under Yang Xingmi by the name of Zheng Fan (鄭璠) ordered his troops to "shoot off a machine to let fire and burn the Longsha Gate," after which he and his troops dashed over the fire into the city and captured it, and he was promoted to Prime Minister Inspectorate for his efforts and the burns his body endured.[1. A later account of this event corroborated with the report and explained that "by let fire (飛火) is meant things like firebombs and fire arrows."[1. Arrows carrying gunpowder was possibly the most applicable form of gunpowder weaponry at the time, as early gunpowder may have only produced an effective flame when exposed to oxygen, thus the rush of air around the arrow in flight would have provided a suitable catalyst for the reaction.[1. The first fire arrows were arrows strapped with gunpowder incendiaries, but in 9. Song generals, Yue Yifang and Feng Jisheng (馮繼升), invented a variant fire arrow which utilizing gunpowder tubes as propellant. Afterwards fire arrows started transitioning to rocket propelled weapons rather than being fired from a bow. These fire arrows were shown to the emperor in 9. Feng Jisheng to demonstrate the gunpowder arrow design, for which he was heavily rewarded. In 1. 00. 0 a soldier by the name of Tang Fu (唐福) also demonstrated his own designs of gunpowder arrows, gunpowder pots (a proto- bomb which spews fire), and gunpowder caltrops, for which he was richly rewarded as well.[1. The imperial court took great interest in the progress of gunpowder developments and actively encouraged as well as disseminated military technology, for example in 1.
