Medieval knight armor suits were essential for protection in battle, evolving over centuries to offer maximum defense and mobility. Early armor included chainmail, a flexible mesh of interlinked rings, offering decent protection against cuts. By the late Middle Ages, full plate armor became common, featuring articulated steel plates covering the entire body. Custom-fitted to each knight, the armor was both functional and a status symbol. Despite its weight, the design allowed for surprising agility, making it an iconic element of medieval warfare.
