Captain America Civil War

Civil War #1 (2006) ignites Marvel's monumental crossover event. Following the devastating Stamford incident, where a superhero battle causes mass casualties, public outcry leads to the proposed Superhuman Registration Act. This pivotal issue establishes the ideological chasm between Captain America, who opposes the act, and Iron Man, who supports it, setting the stage for a universe-altering conflict. It's a key collector's item as the genesis of a defining modern Marvel saga, introducing the core premise that divides Earth's heroes.
