Howl was a modernist Beat poetry work published in 1956 that openly addressed taboo topics like sex, drugs, and homosexuality. It described the lifestyles of Allen Ginsberg's peers in the Beat generation who rejected social and cultural norms. The sexually explicit language in Howl stirred controversy and an obscenity trial but was ultimately ruled to have redeeming social importance. The poem aimed to cry out against repression and mainstream culture through three sections focusing on individuals, social issues, and a message to a friend.
