William's strategy of questioning legitimacy

William used the strategy of questioning everyone else's legitimacy to muddy the political waters and deflect attention from his own illegitimacy. He aimed to destroy the concept of legitimacy, which was a key strategy for him because he was a bastard and not legitimately chosen as king. William challenged the legitimacy of Harold and Edgar, both of whom were proclaimed kings by the wit-hand. By propagating the idea that they were illegitimate usurpers, William aimed to solidify his own position as the legitimate ruler of England.
