How did the armour worn by knights change across the medieval centuries?
Full plate armour came first and was replaced later by lighter mail
Mail was worn in the earlier centuries and full plate armour developed later✓Correct answer
Knights wore only leather and scale armour throughout the whole period
Armour did not change at all between the ninth and the fifteenth centuries
Explanation
Interlinked rings gave flexible protection against cutting blows and were the standard defence of the earlier medieval horseman, while shaped steel plates covering the whole body came into general use only in the later part of the period. Reversing the sequence fails because plate required metalworking skills that developed over those intervening centuries, so it cannot have been the earlier form.
