A component, armor plate, or structural part positioned at or forming the back of something, especially in armor or furniture.
From back (Old English bæc, rear part) + piece (from Old French pece, meaning part or portion), combining to mean 'the back part.'
In medieval armor, the backpiece was often made thinner than the breastplate because soldiers mostly faced forward—a practical reminder that historical armor was designed for real combat, not museum aesthetics.
