When Was Plate Armor First Used?

The earliest knightly plate armour appeared shortly after 1200 in the form of thin plates worn beneath the gambeson. External plate armour began to appear around the middle of the century, at first for elbows, kneecaps, and shins.

When did armor stop being used?

Armour cuirasses and helmets were still used in the 17th century, but plate armour largely disappeared from infantry use in the 18th century because of its cost, its lowered effectiveness against contemporary weapons, and its weight.

Who created plate armor?

The first full suits of plate armor were developed in the Holy Roman Empire during the late Middle Ages, with production peaking in the 16th century. First, small plates were added over chain mail to cover the limbs, then larger ones to protect the torso, until by the 15th century the entire body was encased in steel.
