Dracula was created by Irish author Bram Stoker. He is the titular antagonist of Stoker's 1897 novel Dracula, which was inspired by an actual Wallachian nobleman known as Vlad II, aka Vlad the Impaler. The character has since been imagined as a powerful vampire count in various forms of media and has been played by many notable actors such as Bela Lugosi, Christopher Lee, Frank Langella, Gary Oldman, and even Leslie Nielsen.
