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 the Lonely Mountain (Erebor) was lost. The greater part of the people lived in the Grey Mountains (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 Iron Hills, became King under the Mountain or King of Erebor in TA 2941.
Six kings named Durin ruled the Dwarves of Durin’s Folk. 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 TA 1980. 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.
