Why did antiheroes become popular in comic books during the 1970s?

The rise of the antihero—a character defined by personality flaws or questionable motivations—during the 1970s was primarily a response to the era's significant social and political climate.1

The popularity of these characters was driven by a youth counterculture deeply affected by the Vietnam War and widespread civil and political unrest. As real-world urban violence intensified, comic book publishers began to reflect these darker trends in their storytelling. Characters such as the Punisher and Wolverine emerged during this decade, embodying violent, antiheroic behaviors that resonated with a changing readership.1

Furthermore, as the generation that embraced the comics boom of the 1960s matured, they sought more realistic and sophisticated narratives. Publishers responded to this demand by introducing more violent and complex material, moving away from traditional hero archetypes. This shift was also facilitated by a gradual relaxation of the Comics Code Authority's censorship, which had previously restricted the depiction of darker themes and violence.21
