The thing is that the historical reality of Guy Fawkes is secondary to his appeal as an anti-authoritarian symbol. People rarely attempted such 'daring' actions against established power structures, so, even if he was trying to create an even more authoritarian society, the extremes he went to provoked wonder among a people whose actions were regulated according to an exacting peerage system. His act of rebellion had an attraction apart from his motive, both for the people of his time and for subsequent generations.
Hitherto, most significant rebellions occurred totally in the logic of the peerage system; that is, find the next most legitimate heir whose political sympathies aligned with your own, declare him king by right of his superior virtue and ability, and then push the claim with diplomatic and military force. There were civic rituals to be observed even in rebellion, and it required a high position in the peerage system to initiate.
Guy Fawkes's efforts challenged that notion.
