 However, we know, at least, that the son and immediate successor of Łokietek, Casimir the Great, was about 183 cm tall, which suggests that his father may not have been a dwarf.Some historians coined a hypothesis that the nickname Łokietek had nothing to do with the physical appearance of prince Władysław, but contemptuously described the actual size and political importance of his hereditary domain among the other principalities ruled by the members of the House of Piast, at least as compared to Łokietek's exaggerated ambitions.If this hypothesis is correct, Władysław Łokietek should be rather translated into English as Władysław the Petty.
