- "… they grew immensely rich and famous, and [Thrór] was King under the Mountain again, and treated with great reverence by the mortal men who lived to the South, and were gradually spreading up the Running River as far as the valley overshadowed by the Mountain."
- —Thorin relating the outcome of his grandfather's return to Erebor
The King under the Mountain, also called the King of Erebor, was the hereditary title of the Dwarven ruler who resides at the Lonely Mountain. The King under the Mountain was also by right the King of Durin's Folk.[1]
In The Hobbit, the Dragon Smaug was held to be the only "king" of Erebor. Thorin Oakenshield was in fact in line to be the only rightful King under the Mountain.[2]
