One of the signature differences between humans and animals is that we use weapons. Soft and weak, people wouldn’t survive unprotected in any environment on the planet without tools. The first tool was a weapon.

From the stone as hammer came the hand axe, which when mounted on a stick evolved into the spear. Once humans perfected the art of thrusting something sharp on a long stick at one another, they began to think of better ways to make their sharp point reach the enemy first.

Taking flight
After the thrown spear, projectile technology progressed from muscle-driven weapon systems such as the atlatl and bow-and-arrow to muscle-storage devices like the crossbow, onager, and ballista. (The trebuchet is a kind of muscle-storage system, but muscle power is only used to “cock” the weapon; the counterweight provides the energy that throws the projectile.)

The concept of using chemical reactions to hurl projectiles first originated in the gunpowder rocket, whose first recorded use was by the Chinese thousands of years ago. The idea to put the gunpowder in a tube and use that configuration to hurl a projectile came shortly after. (There are also guns that use compressed air or gas to fire a projectile. Tennis-ball butane cannon use a chemical reaction.)

Cannon everywhere
Cannon were originally valued most for their impressive noise, fire, and smoke, which made for a dramatic show that demoralized the enemy more than it actually hurt him physically. As the technology behind both powder and gun metal improved, cannon matured to where they became the terror of the battlefield they are today.

One of the technology spin-offs of advanced cannon development was smaller, lighter cannon. Cannon could be made so small that a single soldier could carry and fire one all by himself.

Once portable cannon became commonplace, the world changed.

PS: The term “gun” is also used for any gun-like device, especially if it shoots something out like labels or laser beams.

Gun (?), n. [OE. gonne, gunne; of uncertain origin; cf. Ir., Gael.) A LL. gunna, W. gum; possibly (like cannon) fr. L. canna reed, tube; or abbreviated fr. OF. mangonnel, E. mangonel, a machine for hurling stones.]

1.

A weapon which throws or propels a missile to a distance; any firearm or instrument for throwing projectiles by the explosion of gunpowder, consisting of a tube or barrel closed at one end, in which the projectile is placed, with an explosive charge behind, which is ignited by various means. Muskets, rifles, carbines, and fowling pieces are smaller guns, for hand use, and are called small arms. Larger guns are called cannon, ordnance, fieldpieces, carronades, howitzers, etc. See these terms in the Vocabulary.

As swift as a pellet out of a gunne When fire is in the powder runne. Chaucer.

The word gun was in use in England for an engine to cast a thing from a man long before there was any gunpowder found out. Selden.

2. Mil.

A piece of heavy ordnance; in a restricted sense, a cannon.

3. pl. Naut.

Violent blasts of wind.

⇒ Guns are classified, according to their construction or manner of loading as rifled or smoothbore, breech-loading or muzzle-loading, cast or built-up guns; or according to their use, as field, mountain, prairie, seacoast, and siege guns.

Armstrong gun, a wrought iron breech-loading cannon named after its English inventor, Sir William Armstrong. -- Great gun, a piece of heavy ordnance; hence (Fig.), a person superior in any way. -- Gun barrel, the barrel or tube of a gun. -- Gun carriage, the carriage on which a gun is mounted or moved. -- Gun cotton Chem., a general name for a series of explosive nitric ethers of cellulose, obtained by steeping cotton in nitric and sulphuric acids. Although there are formed substances containing nitric acid radicals, yet the results exactly resemble ordinary cotton in appearance. It burns without ash, with explosion if confined, but quietly and harmlessly if free and open, and in small quantity. Specifically, the lower nitrates of cellulose which are insoluble in ether and alcohol in distinction from the highest (pyroxylin) which is soluble. See Pyroxylin, and cf. Xyloidin. The gun cottons are used for blasting and somewhat in gunnery: for making celluloid when compounded with camphor; and the soluble variety (pyroxylin) for making collodion. See Celluloid, and Collodion. Gun cotton is frequenty but improperly called nitrocellulose. It is not a nitro compound, but an ethereal salt of nitric acid. -- Gun deck. See under Deck. -- Gun fire, the time at which the morning or the evening gun is fired. -- Gun metal, a bronze, ordinarily composed of nine parts of copper and one of tin, used for cannon, etc. The name is also given to certain strong mixtures of cast iron. -- Gun port Naut., an opening in a ship through which a cannon's muzzle is run out for firing. -- Gun tackle Naut., the blocks and pulleys affixed to the side of a ship, by which a gun carriage is run to and from the gun port. -- Gun tackle purchase Naut., a tackle composed of two single blocks and a fall. Totten. -- Krupp gun, a wrought steel breech-loading cannon, named after its German inventor, Herr Krupp. -- Machine gun, a breech-loading gun or a group of such guns, mounted on a carriage or other holder, and having a reservoir containing cartridges which are loaded into the gun or guns and fired in rapid succession, sometimes in volleys, by machinery operated by turning a crank. Several hundred shots can be fired in a minute with accurate aim. The Gatling gun, Gardner gun, Hotchkiss gun, and Nordenfelt gun, named for their inventors, and the French mitrailleuse, are machine guns. -- To blow great guns Naut., to blow a gale. See Gun, n., 3.
