Conan the Barbarian by Robert E. Howard was first adapted into comics published Marvel Comics beginning with the series Conan the Barbarian in 1970. Since 2003, Conan has been published by Dark Horse Comics. Marvel Comics introduced a fairly faithful version of Conan in 1970 with Conan the Barbarian, written by Roy Thomas with art initially by Barry Windsor-Smith, then John Buscema and Ernie Chan (aka Ernie Chua). The highly successful Conan the Barbarian series spawned the more adult, black-and-white Savage Sword of Conan in 1974, by Thomas, Buscema, and Alfredo Alcala. Savage Sword of Conan soon became one of the most popular comic series in the 1970s and is now considered a cult classic.
