The Inhumans are a fictional race of superhumans, created by Jack Kirby and Stan Lee. This race appears in various comic book series published by Marvel Comics and exists in that company's shared universe, known as the Marvel Universe. The comic book series of this name have usually focused more specifically on the adventures of the Inhuman Royal Family, and many people associate the name "Inhumans" with this particular team of super-powered beings.
The Inhumans first appeared in Fantastic Four #45 (December 1965), though members Medusa and Gorgon appeared in earlier issues of that series (#36 and #44, respectively). Their home, the city of Attilan, was first mentioned years earlier, in a Tuk the Caveboy story written and drawn by Jack Kirby that appeared in Captain America Comics #1 (March 1941). The city was described as the home of a race that was evolutionarily advanced when human beings were still in the Stone Age.
