The name "Kamar-Taj" does not appear in early Lee/Ditko Doctor Strange stories, but was created later as the country's backstory was fleshed out.

In Marvel Comics, Kamar-Taj is "a hidden land high in the Himalayas"[1][2] and the homeland of Doctor Strange's mentor, the Ancient One, and of the evil sorcerer Kaluu.

The Ancient One left Kamar-Taj and traveled the Earth for centuries, battling evil creatures, gaining the Amulet of Agamotto and the Book of the Vishanti.

[volume & issue needed] He finally settled down in the Himalayan Mountains near Kamar-Taj, building a palace as his home with an order of monks to protect and assist him.

He taught such beings as Doctor Druid and Baron Mordo but found his true apprentice in Stephen Strange, claiming that this boy would become the new Sorcerer Supreme.
