Weapon

A weapon is any tool or device that people use to scare, hurt, or protect themselves. Weapons can be very simple, like rocks or bottles, but many are made just for fighting or hunting. These include things like clubs, swords, and even very advanced tools such as firearms, tanks, and missiles.

People have used weapons for many reasons throughout history. They help in hunting animals for food, in law enforcement to keep communities safe, and in self-defense to protect themselves.

Over time, weapons have changed a lot as technology improves. From basic tools made of wood and stone to today’s complex machines, the way we make and use weapons shows how societies develop and face new challenges.

History

Main article: History of weapons

The use of weapons has played a big role in human history and culture. Weapons are tools used to control animals or other people, which helped humans grow and face new challenges. This led to steady improvements in weapon technology as different groups tried to be better than each other.

Prehistoric

Early humans may have used simple things like sticks or stones as weapons millions of years ago, but the first clear proof of weapons are wooden spears from over 300,000 years ago. Later, around 10,000 years ago, injuries on ancient skeletons show that early people fought with weapons like arrows and clubs.

Ancient history

In ancient times, weapons got much better. Finding metals like copper and bronze led to better tools and weapons, such as swords. Fortifications were built for safety, and weapons like battering rams were made to attack them. The use of iron changed fighting, and the invention of the horse and chariot made battles quicker and more flexible. Warships like triremes were also used in sea battles.

Post-classical history

During the Middle Ages, knights on horseback fought with foot soldiers. Knights used lances for charging, while infantry used spears and bows. The discovery of gunpowder changed warfare forever, leading to the use of muskets and cannons.

In both Europe and the Middle East, similar battle tactics grew. Gunpowder from Asia changed warfare, with musketeers and cannons becoming key on the battlefield.

Modern history

Early modern

The Renaissance brought firearms to Europe. Guns and rockets changed battle tactics. Firearms were different because they used gunpowder to release energy fast, making them much stronger than older weapons. By the 19th century, firearms like the machine gun and ironclad warships changed warfare.

From the 1700s to the early 1900s, weapons changed from being powered by people to using gunpowder. This time, called the "Age of Rifles," saw the creation of rifles for soldiers and cannons for support, as well as early mechanized weapons like the machine gun. New artillery could break old stone forts, leading to new battle tactics.

World War I

World War I showed how fast new technologies could be made for war. Aircraft and ships changed how battles were fought, and new weapons were created to meet the needs of the war.

Interwar

This time between World Wars saw many changes in weapon design. Countries worked on new weapons, and some tried to limit the use of harmful weapons like poison gas through agreements.

Criminalizing poison gas

In the 1920s, many people worked to stop the use of poison gas in war. An agreement called the Geneva Protocol was made in 1925 to ban these gases, though some countries still used them against others who lacked protection.

World War II and postwar

See also: Military technology during World War II

World War II was a time of very quick development in weapons. Many new types of weapons were created, and existing ones were improved. The most powerful was the nuclear bomb. After the war, during the Cold War, countries competed to build more nuclear weapons, but later focused more on conventional weapons for smaller conflicts.

Nuclear weapons

After seeing that using nuclear weapons could destroy the world, countries shifted their focus during the Cold War to developing conventional weapons for limited wars instead of total war.

International arm cooperation

Countries work together with friends to share weapons and skills. This helps them protect bigger areas and show they are serious.

Today, weapons are powerful because of how countries help each other. Sharing missiles, creating defense networks, and building alliances show that teamwork changes how weapons are used. This can influence strategies far beyond any one country.

Types

Weapons come in many forms and are used for different purposes. Some are small and easy for one person to use, like handheld tools. Others are big and need a team, such as machines on vehicles or in forts.

Weapons can also be made for special places, like mountains, ships, or even ones that can fly in the sky or travel through space.

Weapons can be grouped by what they do. Some are meant to shoot far, like tools that launch objects. Others might spread harmful substances or create loud blasts. There are weapons that use energy like light or sound. Each type has its own way of working, from simple tools to very advanced technology.

Manufacture of weapons

Main article: Arms industry

The arms industry makes and sells tools for protection and fighting. It includes making and caring for military tools. Many countries have their own arms industry to help their armies. Some countries also sell weapons to others for self-defense, hunting, or sports.

Governments give out contracts for these weapons, which can be very important. This link between government and weapons making can create what is called a "military–industrial complex," where the army, business, and politics work closely together.

Legislation

Rules control making, owning, trading, and using many weapons. These rules come from local or central governments or from international agreements. Some examples include:

• The right of self-defense
• Knife legislation
• Air gun laws
• Gun law
• Arms trafficking laws
• Arms control treaties
• Space Preservation Treaty

Gun laws

Main article: Gun laws

Every country has laws that control parts of gun use, such as making, selling, moving, owning, changing, and using small guns by regular people.

Countries that control who can get guns usually limit which types of guns people can have and who can get a license to have them. There might be different licenses for hunting, sport shooting, self-defense, collecting, and carrying guns hidden, each with its own rules.

Arms control laws

Main article: Arms control

International treaties and agreements set limits on making, storing, spreading, and using weapons, from small guns and big weapons to very powerful weapons. Arms control is usually done through diplomacy, where countries agree to these limits. Sometimes, countries try to make sure others follow these limits too.

Arms trafficking laws

Main article: Arms trafficking

Arms trafficking is the illegal trading of hidden weapons and ammunition. What is allowed when trading guns changes a lot depending on where you are. In 2001, the United Nations made a protocol against making and trading illegal guns. This agreement asked governments to get rid of illegal guns and to license new guns to make sure they are real. It was signed by 122 countries.

Lifecycle problems

There are safety problems with weapons that are already in use, stored, or need to be removed.

Some places have been used to throw away old weapons like bombs and landmines, which can be very dangerous. Some weapons, called unexploded ordnance, did not go off when they were first used and can still cause harm many years later. Removing these is very hard and can be unsafe for people living nearby. There have also been worries about powerful weapons being stolen and used by bad people, especially after big changes in some countries.

In science fiction

Science fiction stories often have unusual and exciting weapons. Some of these weapons, like certain types of guns, began in science fiction and are now real. Others, such as force fields and stasis fields, are only in stories and may not be possible in our world.

Popular science fiction shows and movies have many famous weapons. For example, the phaser from Star Trek and the lightsaber and blaster from Star Wars are well-known. These weapons make the stories more exciting.
