Justice League #1

Justice League #1, published in 1960 by DC Comics, marked the official debut of the Justice League of America in 'The Brave and the Bold' issue #28, though it quickly spun off into its own self-titled series. Created during the Silver Age of comic books, the title was spearheaded by editor Julius Schwartz, who sought to revitalize the concept of a superhero team. He tasked writer Gardner Fox and artist Mike Sekowsky with bringing together DC’s most iconic heroes—Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and Martian Manhunter—to battle the alien conqueror Starro the Conqueror.

The design and narrative approach of the series reflected the optimism and sci-fi fascination of the early 1960s. By assembling characters who previously occupied their own isolated titles, Schwartz successfully created a shared universe that felt expansive and adventurous. The series was met with immense popular success, effectively setting the standard for the modern 'super-team' archetype and influencing the structure of collaborative storytelling in comics for decades to follow.
