This is a virtual collection of weapons in the web site. Weapons are items that can be used for offense or defense. Weapons can be used both in wartime and in peacetime. Examples of peacetime use are hunting or some sports. Cave paintings are the oldest evidence of the use of weapons. During the Neolithic, the main weapons were thick rods and unshaped stones. It is believed that the use of these primitive weapons began as early as two million years ago. During the Middle Ages, weapons saw a great revolution and many sophisticated types of spears, shields, swords and bows were made. In the 19th century and the beginning of the 20th century, firearms were actively improved and completely replaced projectile weapons.
