On the origins of gunpowder technology, historian [[Tonio Andrade]] remarked, "Scholars today overwhelmingly concur that the gun was invented in China."{{sfn|Andrade|2016|p=75}} Gunpowder and the gun are widely believed by historians to have originated from China due to the large body of evidence that documents the evolution of gunpowder from a medicine to an incendiary and explosive, and the evolution of the gun from the [[fire lance]] to a metal gun, whereas similar records do not exist elsewhere.{{sfn|Andrade|2016|pp=75–76}} As Andrade explains, the large amount of variation in gunpowder recipes in China relative to Europe is "evidence of experimentation in China, where gunpowder was at first used as an incendiary and only later became an explosive and a propellant... in contrast, formulas in Europe diverged only very slightly from the ideal proportions for use as an explosive and a propellant, suggesting that gunpowder was introduced as a mature technology."{{sfn|Andrade|2016|p=76}}

However, the history of gunpowder is not without controversy. A major problem confronting the study of early gunpowder history is ready access to sources close to the events described. Often the first records potentially describing use of gunpowder in warfare were written several centuries after the fact, and may well have been colored by the contemporary experiences of the chronicler.{{sfn|Ágoston|2008|p=15}} Translation difficulties have led to errors or loose interpretations bordering on [[artistic licence]]. Ambiguous language can make it difficult to distinguish gunpowder weapons from similar technologies that do not rely on gunpowder. A commonly cited example is a report of the [[Battle of Mohi]] in Eastern Europe that mentions a "long lance" sending forth "evil-smelling vapors and smoke", which has been variously interpreted by different historians as the "first-gas attack upon European soil" using gunpowder, "the first use of cannon in Europe", or merely a "toxic gas" with no evidence of gunpowder.{{sfnm|Partington|1999|1p=198|Saunders|1971|2p=198}} It is difficult to accurately translate original Chinese alchemical texts, which tend to explain phenomena through metaphor, into modern scientific language with rigidly defined terminology in English.{{Sfn|Kelly|2004|p=22}} Early texts potentially mentioning gunpowder are sometimes marked by a linguistic process where [[semantic change]] occurred.{{sfn|Partington|1999|pp=xvi–xvii}} For instance, the Arabic word ''naft'' transitioned from denoting [[naphtha]] to denoting gunpowder, and the Chinese word ''pào'' changed in meaning from [[trebuchet]] to a [[cannon]].{{sfn|Purton|2010|pp=108–09}} This has led to arguments on the exact origins of gunpowder based on etymological foundations. Science and technology historian Bert S. Hall makes the observation that, "It goes without saying, however, that historians bent on special pleading, or simply with axes of their own to grind, can find rich material in these terminological thickets."{{sfn|Partington|1999|pp=xvi–xvii}}

Another major area of contention in modern studies of the history of gunpowder is regarding the transmission of gunpowder. While the literary and archaeological evidence supports a Chinese origin for gunpowder and guns, the manner in which gunpowder technology was transferred from China to the West is still under debate.{{sfn|Andrade|2016|p=75}} It is unknown why the rapid spread of gunpowder technology across Eurasia took place over several decades whereas other technologies such as paper, the compass, and printing did not reach Europe until centuries after they were invented in China.{{sfn|Andrade|2016|p=76}}
