Stirrup, 975–1075 Anglo-Scandinavian, possibly from southern England Iron inlaid with copper alloy
Though the Vikings are best known as seafaring warriors, through contact with Europe they grew ever more adept as cavalrymen. Changes in stirrup design gave a tactical advantage in that they permitted a warrior to shift his weight onto the stirrups and thereby wield his weapons with greater height and force. This stirrup, decorated with a distinctive technique of iron inlay, is of a type found in England and may have been introduced in the renewed Viking attacks at the end of the tenth century.
the stirrup was imported to Germany by the early eighth century and the Anglo-Saxons aquired it soon after. Previously Germanic peoples had only ridden horses to the battle, but this new technology allowed warriors to ride a horse into battle rather than just to a battle. Being able to stand in the stirrups allows for more freedom of movement, with a sword or spear.
