In the 2006–2007 company-wide story arc “Civil War“, Rogers opposes the new mandatory federal registration of super-powered beings, and leads the underground anti-registration movement. After significant rancor and danger to the public as the two sides clash, Captain America voluntarily surrenders and orders the Anti-Registration forces to stand down, feeling that the fight has reached a point where the principle originally cited by the anti-registration forces has been lost.
