King under the Mountain

The title taken by Thráin I, founder of the Dwarf-kingdom at Erebor, the Lonely Mountain, and maintained by those Kings of Durin's Folk who dwelt there. The line was broken twice, once by Thorin I (he and four generations of his descendants ruled from the Grey Mountains, not Erebor), and once by the dragon Smaug (who claimed the title for himself). In both cases, the line was restored to a rightful heir.
