The Justice League (of America) is a team of comic book superheroes in the DC Comics Universe.
The League was a 1960s update of the Golden Age of Comic Books team, the Justice Society of America.
Sometime in the early 1960s, a separate team took on the name and mantle of Justice Society of America, and began working closely with the Justice League (throughout various universes and relaunches) to the present day.
The result is the team being prominently featured in many ongoing series, annuals, miniseries, maxiseries, one-shots, graphic novels, trade paperbacks and intercompany crossovers published by DC Comics.
All titles and stories are published exclusively by DC Comics under their standard imprint, unless otherwise noted.
