Guy Fawkes, on the 5th of November, who attempted to destroy Parlaiment using fertilizer as an explosive.





This is hinted at the very beginning of the movie, ';Remember, remember, the 5th of November, the gun-powder, treason, and plot.';..





I have read the graphic novel, you should pick it up.


From Barnes and Noble or Amazon.com ';V for Vendetta'; by Alan Moore, the author who wrote the story.





The protestors that wear the mask should stand for Vs rebellion against oppression. V himself from the graphic novel stood for Anarchy.


';Let us destroy. From the ashes, we will rebuild';
