The history of firearms begins in 10th-century China, where early gunpowder weapons emerged from the innovation of mounting tubes filled with explosive powder onto spears, creating portable “fire lances.” Over the following centuries, these devices evolved into a wide range of weapons, including handheld firearms such as flintlocks and blunderbusses, as well as fixed artillery pieces like cannons. By the 15th century, gunpowder technology had spread throughout Eurasia. Firearms played decisive roles in major historical events, including the fall of the Byzantine Empire and the expansion of European colonial empires in the Americas, Africa, and Oceania.
The pace of innovation accelerated dramatically in the 19th and 20th centuries with the development of metal cartridges, rifled barrels, repeating mechanisms, belt-fed systems, and ultimately automatic weapons such as machine guns. While early firearms relied on black powder as a propellant, modern weapons use smokeless powder or other advanced propellants.
Separate from firearms but often mentioned in discussions of early weaponry is Greek fire, an incendiary weapon reportedly used by the Byzantine Empire between the 7th and 14th centuries. Though sometimes delivered through siphon-like flamethrowers or grenades, its composition remains uncertain and it does not appear to be directly related to Chinese gunpowder weapons or later firearms.
10th–12th Centuries: Origins in China
The first true firearms developed in China following the invention of gunpowder. The earliest known depiction of a gunpowder weapon appears in a 10th-century silk banner from Dunhuang illustrating a fire lance. These early weapons consisted of paper or bamboo tubes filled with black powder and attached to spears, functioning primarily as flamethrowers. Over time, shrapnel or pellets were added so that projectiles would be expelled along with the flame.
Historical records, such as accounts of the 1132 siege of De’an during the Jin–Song Wars, describe the use of fire lances in battle. As gunpowder formulas improved—particularly through increased saltpeter content—barrels were reinforced with metal to withstand greater explosive force. Eventually, projectiles were shaped to fit the barrel more precisely, leading to the development of the hand cannon: a metal-barreled weapon firing a properly sized projectile using high-nitrate gunpowder.
By the 12th century, sculptures in Sichuan depicted vase-shaped bombards firing cannonballs, indicating the clear transition from flame-based weapons to true projectile firearms.
13th Century: Expansion Across Asia
The oldest surviving firearm, the Heilongjiang hand cannon dated to 1288, was discovered in northeastern China. Contemporary records describe its use in suppressing rebellions during the Yuan dynasty.
Gunpowder technology spread beyond China during the Mongol expansions of the 13th century. Campaigns into Southeast Asia likely transmitted knowledge of firearm production. Inscriptions from Vietnam in 1312 reference guns and ammunition among captured spoils, suggesting regional familiarity with such weapons.
Some scholars argue that early cannon were used in the 1260 Battle of Ain Jalut between the Mamluks and Mongols, though historians continue to debate the timing and origin of gunpowder’s introduction to the Islamic world.
14th–15th Centuries: The Middle East and Europe
By the late 13th or early 14th century, firearms had appeared in the Middle East. The Ottoman Empire began using handheld firearms, including early arquebuses and muskets, between the late 14th and mid-15th centuries. Firearms manuals from China in the late 16th century even described Turkish muskets as superior to their European counterparts.
In Southeast Asia, firearm production developed through the blending of Arab, Turkish, Portuguese, and local traditions. The capture of Malacca in 1511 facilitated further technological exchange, leading to the Indo-Portuguese matchlock tradition and the creation of the istinggar arquebus.
In South Asia, firearms were recorded in use by the late 14th century. The Mughal Empire incorporated Turkish firearms in the 16th century, contributing to decisive victories such as the First Battle of Panipat. Mughal emperors refined matchlock design, while other regional powers—including the Marathas, Mysore under Tipu Sultan, and the Sikh Empire under Maharaja Ranjit Singh—developed their own artillery and firearm traditions.
In Europe, gunpowder likely arrived via trade routes such as the Silk Road or through Mongol invasions. By the mid-14th century, cannons were used in sieges such as the English campaign at Calais. Smaller portable hand cannons appeared in Italy in the late 14th century. During the Hussite Wars (1419–1434), firearms became central to battlefield tactics, and the Czech term houfnice eventually gave rise to the English word “howitzer.”
Early Modern Developments
During the early modern period, ignition systems evolved from matchlocks to wheellocks, snaplocks, flintlocks, and finally percussion caps. Paper cartridges were introduced before the late 16th century, and bayonets appeared in France during the same era.
The development of fixed metallic cartridges in the 19th century revolutionized firearms. Brass cartridge cases combined primer, powder, and projectile into a single waterproof unit. When fired, the brass expanded to seal the breech, preventing dangerous gas escape and greatly improving reliability.
Institutions such as the Springfield Armory in Massachusetts played a key role in advancing breech-loading rifles during the mid-19th century. By this time, metallurgy had progressed sufficiently to allow mass production of durable ammunition cases.
Repeating and Automatic Firearms
Repeating firearms, capable of firing multiple rounds before reloading, emerged through mechanisms such as bolt-action, lever-action, and revolving cylinders. Revolvers, introduced in the 19th century, held cartridges in a rotating cylinder that functioned as both magazine and chamber. Single-action revolvers required manual cocking before each shot, while double-action designs allowed firing by simply pulling the trigger.
Self-loading and automatic weapons represented another major leap. The Gatling gun, invented during the American Civil War, used a hand-cranked mechanism. In 1884, Hiram Maxim developed the first true fully automatic machine gun, which used recoil energy to cycle rounds.
The early 20th century saw further innovations:
-
The Mondragón rifle (1908) became one of the first successful self-loading rifles.
-
The MP18, introduced in 1918, was the first practical submachine gun.
-
The German StG 44 of World War II became the first widely recognized assault rifle, firing intermediate cartridges with selective fire capability.
-
The AK-47 later became the most widely produced assault rifle in history.
Battle rifles such as the M1 Garand retained powerful full-size cartridges, but their recoil made fully automatic fire difficult to control, leading many militaries to adopt intermediate-caliber assault rifles instead.
Overall, firearms evolved from simple flame-projecting tubes in medieval China into highly sophisticated mechanical and chemical systems that reshaped warfare, politics, and global history.
