Kings of Durin's Folk

The Kings of Durin's Folk were those of the House of Durin who ruled as kings, even when in exile. The kings were all descended from Durin the Deathless of the First Age; in fact, five of the kings after Durin I were held to be reincarnations of him by the Dwarves. No complete list of all kings is known. The table below shows the names of those Kings who have been recorded, or whose existence could be deduced. In the table all information was obtained from The Lord of the Rings, Appendix A, "Durin’s Folk" unless otherwise indicated. The " Realm(s) " column indicates which place or places that the kings dwelt during their reigns.

Name	Birth	Death	Realm(s)	Historical Notes
Durin I the Deathless	First Age	First Age	Khazad-dûm	One of the seven Fathers of the Dwarves and founder of the Longbeards, Durin's folk. He ruled his people for centuries - so long, in fact, that he became known as the 'Durin the Deathless' - but eventually he died during the First Age. He discovered the caves of Khazad-dûm and began his reign there.
Durin II	Unknown	Unknown	Khazad-dûm
Durin III	Unknown	Unknown	Khazad-dûm	He was the king of Khazad-dûm at the time of the forging of the Rings of Power (sometime between S.A. 1500 and 1590) and a great friend of Celebrimbor the Lord of Eregion to the west. He received one of the Rings (later known as the Ring of Thrór) as a gift from his friend.
Durin IV	Unknown	Unknown	Khazad-dûm
Durin V	Unknown	Unknown	Khazad-dûm
Durin VI	1731	1980 †	Khazad-dûm	He was king when the Balrog was awakened in 1980. After he was killed by it the Balrog was called Durin's Bane and Khazad-dûm was known as Moria.
Náin I	1832	1981 †	Khazad-dûm	He reigned for just one year before was also slain by Durin's Bane.
Thráin I	1934	2190	Erebor	He led a great part of his people away from Khazad-dûm into the north and east of Middle-earth and founded the Kingdom under the Mountain in 1999.
Thorin I	2035	2289	Erebor, Grey Mountains	Discerning that the great host of his people were gathering in the northern range of the Grey Mountains, Thorin I abandoned Erebor and removed there in 2210.
Glóin	2136	2385	Grey Mountains
Óin	2238	2488	Grey Mountains
Náin II	2338	2585	Grey Mountains	In 2570, the prosperous Dwarves began to suffer attacks by the dragons of the north.
Dáin I	2440	2589 †	Grey Mountains	His short reign came to a swift end when he was slain by a cold-drake before his own doors. He was succeeded by the eldest of his three sons.
Thrór	2542	2790 †	Erebor, exile, Dunland	He led his people out of the dragon-infested north back to the Lonely Mountain, while his younger brother Grór led some part of their people further east, to settle in the Iron Hills. He had been King under the Mountain for more than 180 years when the great dragon Smaug descended on his kingdom and sacked it. He escaped the destruction with his son and grandson, and went wandering in the wild before settling in Dunland. Later, went to reclaim Khazad-dûm where he was murdered by Azog the Orc, a crime that provoked the War of the Dwarves and Orcs.
Thráin II	2644	2850 †	Dunland, Ered Luin	He avenged his father's death with the defeat of Azog's Orcs at the Battle of Azanulbizar. In the early part of his reign, he dwelt in Dunland, but he later moved northwest to the Ered Luin west of Eriador. Before his reign ended, he resolved to return to Erebor, but wandering in the wild he was captured in 2845 and died in the dungeons of the Necromancer.
Thorin II Oakenshield	2746	2941 †	Ered Luin, Erebor	He ruled as King in the Ered Luin for many years, but like his father before him he at last determined to return to his ancient home of Erebor. Accompanied by Gandalf and Bilbo Baggins, he led a troop of companions into the east, and against all hope recovered the Lonely Mountain from Smaug. After Smaug's death, the Battle of Five Armies was fought before Erebor, and Thorin was slain. The only remaining descendants of Thrór's line, Thorin's young nephews Fíli and Kíli, were also lost in the battle. So the descent of the Kingship passed to the line of Thrór's younger brother Grór, and specifically to Grór's grandson Dáin Ironfoot.
Dáin II Ironfoot	2767	3019 †	Ered Luin, Erebor	He ruled in prosperity as King under the Mountain for many years until the time of the War of the Ring. He was slain in that war, in the Battle of Dale.
Thorin III Stonehelm	2866	Early Fourth Age	Erebor	He was besieged in Erebor after the loss of his father, but when news reached the forces of Sauron that their master had been defeated, he was able to drive them back. With Thorin III, detailed records of the reigns of the Kings come to an end, but there is a record of just one of his descendants.
Durin VII	Unknown	Unknown	Khazad-dûm	He was said to be the last of the House of Durin to rule over Durin's Folk. Durin's Bane had been destroyed in the War of the Ring, so that Khazad-dûm lay open for recovery by its ancient owners, and it is said that it was Durin VII who at last achieved this.

Durin I died before the end of the First Age, so that between his rule and that of Thorin III, the Kings of Durin's line ruled for a period of about 6,500 years. Given that the average length of a reign among the Longbeards seems to have been roughly a century, it can be deduced that there were probably about fifty Kings' names missing from this list.
