Durin's folk

Durin's folk is the most important folk of Dwarves.

Durin's folk were by right the inhabitants of Khazad-dûm, also called the Longbeards. They also claimed Mount Gundabad as a home, until this was conquered by Orcs. Their first King was Durin the Deathless.

In the later half of the Third Age, up to the time of the Quest of Erebor, most Dwarves of Durin's Folk lived in exile, as both Khazad-dûm and Erebor were lost. The greater part of the people lived in the Ered Mithrin, but a smaller group lived as exiles in the west near the ruins of Belegost. The remnants of the royal house were among them. Durin's Folk was reunited when Dáin II, Lord of the Ered Mithrin, became King of Erebor in 2941 T.A..

The Dwarves of Durin's Folk were ruled by six kings named Durin. More than just a succession of fathers and sons, this Durin was seen as a reincarnation of his previous self, and had memories of his earlier lives. This lasted until Durin VI, who was killed by Durin's Bane in 1980 of the Third Age. After him Durin did not return to his people for many years, until in the Fourth Age a Durin VII appeared, descendant of Thorin III son of Dáin II Ironfoot, and a descendant in direct line from Durin the Deathless. Durin VII would become known as Durin the Last.
