In 1971, the Comics Code Authority relaxed some of its longstanding rules regarding horror comics, such as a virtual ban on vampires. Marvel had already tested the waters with a "quasi-vampire" character, Morbius, the Living Vampire, but the company was now prepared to launch a regular vampire title as part of its new line of horror books. After some discussion, it was decided to use the Dracula character, in large part because it was the most famous vampire to the general public, and also because Bram Stoker's creation and secondary characters were by that time in the public domain.
