Explanation:

Fencing is the art of attack and defence with a sword or similar weapon. Modern fencing is a recreational and competitive sport, but its rules and techniques are derived from those originally developed for efficient swordplay in duelling. During the middle ages (5th century to 15th century) the sword was an offensive weapon used for cracking armor, and the shield was used as a defence. After gunpowder came into general use, heavy defensive armour became obsolete, and the sword became a defensive as well as an offensive weapon. In the 16th century the rapier was introduced in italy, and the art of fencing was rapidly systematized in fencing schools. A dagger in the other hand, and later a folded cloak, replaced the shield. Eventually the non sword arm was left free and held away from the sword arm to minimize the target area.
