The Black Knightsare a group of revolutionaries created by Lelouch (under the guise of Zero) in his campaign to overthrow Britannia. He introduces the group to the world as an organization which protects those without power from those who have it. Under his leadership, the Black Knights grow in strength exponentially, becoming a force rivaling the Britannian army. Ultimately, the Black Knights gain legitimacy when thenewly-formed United Federation of Nations contracts the Black Knights (organized as a private military company) to become their military force.
