Thráin II (Third Age 26442850, aged 206 years) was King of Durin's Folk for 60 years, from T.A. 2790 to 2850, during their exile from Lonely Mountain. He was the son of Thrór and father of Thorin II, Frerin, and Dís. Thorin II would later be known as Thorin Oakenshield.[1]


Thráin fled with his father and a small group of companions when the dragon Smaug in T.A. 2770 descended on Lonely Mountain and sacked the Dwarven kingdom. King Thrór, Thráin, and the others eventually settled in Dunland and scratched out a meager living. Thrór was devastated by the loss of Erebor and left his people to journey north. He took a single companion, Nár, but left his son with his Ring of Power, along with the map and key to Lonely Mountain.

In T.A. 2790[2] Nár returned to tell Thráin that his father had been captured and butchered by the Orc-chieftain Azog when they had journeyed to the mines of Moria. Even worse, Azog had beheaded Thrór and carved his own name on Thrór's forehead to show the Dwarves that an Orc now ruled their ancestral home.

Thráin sat for seven days without speaking, until he stood and said "This cannot be borne!".[1]

War of the Dwarves and Orcs

Filled with righteous anger, by T.A. 2793[2] Thráin had gathered together a massive army of Dwarves to wage the War of the Dwarves and Orcs. The army included the exiles of the Lonely Mountain, Thráin's kin from the Iron Hills under his uncle Grór, and even some Dwarves not of Durin's folk (probably the four Dwarf clans from the Orocarni in the east). One by one they assaulted the Orc-holds of the Misty Mountains, destroying their great warrens in Mount Gundabad and eventually facing Azog himself in Dimrill Dale (Azanulbizar in Khuzdul) before the East-gate of Moria.

In T.A. 2799[2] Thráin and his army fought the bloody Battle of Azanulbizar. Thráin was blinded in one eye and suffered a leg-wound. While the Orcs were vanquished and Azog slain, the Dwarves took heavy losses, including Thráin's son Frerin, his cousin Náin, and Fundin father of Dwarven hero Balin.

King Thráin II wanted to enter Moria and reclaim it, but the Dwarves not of Durin's folk refused, saying that the city was not their Fathers' House; they had honoured Thrór's memory by fighting, and this was enough. Dáin Ironfoot had peered within the East-gate and also warned Thráin that Durin's Bane still dwelt within Khazad-dûm.[1]

Wanderings and imprisonment

After the war, Thráin and Thorin led the exiles of Lonely Mountain west to live in the southern Blue Mountains where they settled in T.A. 2802.[2] Over the next forty years Thráin grew increasingly consumed with the lost riches of the Lonely Mountain. This may have been partly because of the Ring of Thrór.

In T.A. 2841[2] he left the Blue Mountains with a small group that included Balin and Dwalin. Travelling east, the group was constantly harassed by wolves, Orcs, and other fell creatures. In 2845,[2] while camped under the eaves of Mirkwood, Thráin disappeared and would never be seen again by his kin. The King of Durin's folk had been captured by Sauron's agents and was taken to the fortress of Dol Guldur in southern Mirkwood. There Sauron tortured Thráin, took back the last of the seven Dwarf-rings, and left him in the dungeon to die.

In T.A. 2850,[2] while on a reconnaissance mission to Dol Guldur, Gandalf came upon Thráin, who was so diminished that he could not even remember his own name. Thráin gave Gandalf his last two possessions, the key and map to the Lonely Mountain, and shortly thereafter died. Gandalf left him without knowing who he was.[1]


Much later Gandalf met Thorin Oakenshield near Bree and realized that the Dwarf he had found in Dol Guldur was Thráin, the vanished King of Durin's folk. Gandalf and Thorin discussed reclaiming Lonely Mountain, and Gandalf gave much assistance to Thorin and Company, including the map and key to Lonely Mountain, along with a suggestion that they include a burglar in their quest.[1]

Gandalf mentioned to the Fellowship, as they were debating about going into Moria, that he had been in the mines before looking for Thráin.[3]


Þráinn is a dwarf from the Dvergatal. It means "Stubborn".[4]

2012-14: The Hobbit (film series):

The young Thráin during the Dwarves' reign at Erebor is portrayed by Thomas Robins in The Hobbit: An Unexpected Journey.[5] During the scenes from the Battle of Azanulbizar in the same film, he is allegedly played by Mike Mizrahi,[6] though no footage seems to appear of him in the Theatrical Version of the films. Finally, in the Extended Edition of The Hobbit: The Desolation of Smaug, he is portrayed by Antony Sher at old age in Dol Guldur, and by Mike Mizrahi at young age, during the Battle of Azanulbizar.

2013: The Hobbit: The Desolation of Smaug:

In the Extended Edition of this film, Thráin Is first seen in a flashback to the Battle of Azanulbizar during the prologue while Gandalf and Thorin discuss his possible whereabouts. In this flashback, Thráin insists Thorin stay back as he leads a charge toward the Great Gates (though he is not seen again during the battle or its aftermath).
Old and delirious, Thráin is again seen later at Dol Guldur when Gandalf arrives to investigate. He tracks the Wizard, and ultimately attacks him in a fit of madness. Gandalf is able to overtake him and calm him. Thráin warns Gandalf to not let Thorin near the Lonely Mountain because he has learned that Smaug is in league with The One. He ultimately helps Gandalf navigate through the fortress before Azog and several other Orcs attack. The two of them try to escape but are eventually stopped by the shadow of the Necromancer. Thráin tells Gandalf to tell Thorin that he loved him, and is swallowed up the shadow, which then reveals itself as Sauron to Gandalf.

2013: Guardians of Middle-earth:

Thráin is a warrior-type "guardian" with four abilities: Hammer throw, Dwarven valor, Lethal blow and Durin's Wrath.[7]

2021: The Lord of the Rings Online:

Thráin appears in an extended flashback depicting the Battle of Azanulbizar, which closely follows the description given in the books.
