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 the kings ruled from during their reigns.

Name	Birth	Death	Realm(s)	Historical Notes
Durin I the Deathless	Between Y.T. 1050 and 1250	Late 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 before the end of the First Age. He established the city of Khazad-dûm and began his reign there.
Durin II	Unknown	Unknown	Khazad-dûm	Nothing is recorded about his reign.
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. He received one of the Seven Rings (later known as the Ring of Thrór) as a gift from his friend. The Alliance of Dwarves and Men in the North is said to have come to an end during his reign.
Durin IV	Unknown	Unknown	Khazad-dûm	Nothing is recorded about his reign.
Durin V	Unknown	Unknown	Khazad-dûm	Nothing is recorded about his reign.
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 he 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 founded the Kingdom under the Mountain in 1999. The Arkenstone was discovered during his reign in the Lonely Mountain.
Thorin I	2035	2289	Erebor, Ered Mithrin	Learning that his people were regrouping in the Grey Mountains, Thorin I abandoned Erebor and reestablished the throne in the Ered Mithrin in 2210.
Glóin	2136	2385	Ered Mithrin	Nothing is recorded about his reign.
Óin	2238	2488	Ered Mithrin	Towards the very end of Óin's reign, in T.A. 2460, the Shadow returned to Dol Guldur in Mirkwood with increased strength; and in c. T.A. 2480 Orcs began to spread again in the Misty Mountains in order to block all passes into Eriador, whilst Sauron populated Moria with his creatures.
Náin II	2338	2585	Ered Mithrin	In 2570, the prosperous Dwarves began to suffer attacks by the Dragons of the North.
Dáin I	2440	2589 †	Ered Mithrin	His reign came to a swift end when he was slain by a cold-drake before the entrance to his halls.
Thrór	2542	2790 †	Ered Mithrin, Erebor, exile, Dunland	He led his people out of the Grey Mountains back to the Lonely Mountain. He had been King under the Mountain for more than 180 years when the dragon Smaug descended on the mountain and sacked it. He escaped the destruction, and went wandering in the wild before settling in Dunland. Later, he went to reclaim Khazad-dûm where he was murdered by Azog the Orc-chieftain, 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 and established a new realm. Before his reign ended, he resolved to return to Erebor, but while wandering in the wild he was captured in 2845 and died in the dungeons of the Necromancer. Consequently, the Ring of Thrór was lost to Sauron.
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 was 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, Thorin was slain in the Battle of Five Armies. The only remaining descendants of Thrór's line, Thorin's nephews Fíli and Kíli, were also lost in the battle. So the Kingship passed to the line of Grór, Thrór's younger brother; specifically, to his grandson Dáin II Ironfoot.
Dáin II Ironfoot	2767	3019 †	Erebor	Dáin was a descendant of Grór and lord of the Dwarves of the Iron Hills. Dáin joined his father's contingent in the Battle of Azanulbizar, at which time he slew Azog. After Thorin's death in the Battle of Five Armies, Dáin was crowned King of Durin's Folk. 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 the Battle of Dale.
Thorin III Stonehelm	2866	Unknown	Erebor	Thorin himself succeeded to the kingship when his father was killed during the War of the Ring in T.A. 3019. His realm was under the crown and protection of the new King of Gondor and Arnor. During his rule, Gimli led a number of Dwarves south to Aglarond, where a new lordship was established.
Durin VII	After Fo.A. 171	Unknown	Khazad-dûm	He was the last of the reincarnations of Durin hence his title as "Durin the Last". He was a direct descendant of Thorin III Stonehelm. His birth was apparently prophesied upon the accession of Dáin II after the Battle of Five Armies. He led Durin's Folk back to Khazad-dûm at some unknown time after Fo.A. 171, where they remained "until the world grew old and the Dwarves failed and the days of Durin's race were ended".

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 that have went unmentioned.
