Most of the Dwarves in The Lord of the Rings survive the War of the Ring, help rebuild Middle‑earth, briefly flourish in the Fourth Age, and then slowly dwindle until their race finally fades from history.

What Happened to the Dwarves in LOTR?

Big picture

After Sauron’s defeat, the Age of Men begins, and the Dwarves have a kind of last “golden afterglow” before they decline.

They do not sail West like the Elves; instead, their numbers slowly lessen until “the days of Durin’s race ended.”

During and right after the War of the Ring

  • While the main story focuses on Gondor and Rohan, northern Dwarves and Men fight their own large battles around Erebor and Dale.
  • King Dáin II Ironfoot of Erebor and King Brand of Dale are both killed defending their lands against Sauron’s Easterling forces.
  • The Dwarves retreat into the Lonely Mountain, are besieged, and then drive the enemy away once news of Sauron’s fall destroys the Easterlings’ morale.

This northern front is happening roughly parallel to the Siege of Gondor and the Battle of the Pelennor Fields.

Gimli and the Dwarves you know from the Fellowship

  • After the war, Gimli leads a group of his people (Durin’s Folk) to settle in the Glittering Caves at Helm’s Deep, becoming “Lord of the Glittering Caves.”
  • His colony helps rebuild Rohan and Gondor, including reforging the Great Gate of Minas Tirith in mithril and steel.
  • Later tradition says Gimli, out of friendship with Legolas and his reverence for Galadriel, is allowed to sail West to the Undying Lands—he is the only Dwarf ever said to do so.

So for the Fellowship Dwarf, the end is unusually blessed: great honor in Middle‑earth, then a unique final journey.

Erebor, Durin’s Folk, and Moria after LOTR

  • After Dáin II dies, his son Thorin III Stonehelm becomes King under the Mountain and helps restore Dale and Erebor; they become close allies of King Elessar (Aragorn).
  • Under Thorin III, the Dwarves of Erebor prosper “well into the Fourth Age.”
  • Eventually his descendant Durin VII the Last leads the Dwarves back to Khazad‑dûm (Moria) and restores it for a time to its ancient greatness.
  • Tolkien notes only that the Dwarves dwelt there “until the world grew old and the days of Durin’s race ended,” leaving the ultimate details vague and a little melancholy.

In other words, they get their legendary home back for a final era, but it’s clearly their last one.

Long‑term fate in the Fourth Age

  • After the Ring is destroyed, the Dwarves have about a century (and more in Tolkien’s broader timeline) of renewed strength: rebuilding, forging, trading, and cooperating closely with Men.
  • But the new age is explicitly the “Age of Men,” and Tolkien indicates that the Dwarves gradually fade, much like the Elves and Hobbits, though in a different way.
  • No mass death event is described; instead, it’s implied that their numbers decline over time until they simply vanish from the later histories of Men.

Some readers interpret this as eventual functional extinction, others as them withdrawing so far into the deeps that Men mostly forget them.

How forums and fans talk about it (trending angle)

Recent forum discussions and articles highlight a few common fan viewpoints:

  1. “Quiet extinction” view
    • Argues that Dwarves slowly die out due to low birth rates and accumulated losses over ages of wars and monsters.
  1. “Hidden people” view
    • Suggests that some Dwarves survive in deep halls but pass out of the notice of Men, becoming more legend than reality.
  1. Bittersweet last golden age
    • Emphasizes that post‑Ring Dwarves get real victories: Erebor secure, Khazad‑dûm briefly restored, alliances with Gondor and Dale—before the curtain finally falls.

Because Tolkien leaves the ending deliberately hazy, current articles and lore videos still spark debate about whether they truly go extinct or simply “fade” like other elder races.

Mini FAQ

Do Dwarves sail to the Undying Lands?

  • No, as a rule they do not; only Gimli is ever said to be allowed to go, and even that is a special exception rather than a general Dwarven fate.

Do we know the exact end of their race?

  • Not really. Tolkien only hints that in some far future “the days of Durin’s race ended,” without describing how.

Are there Dwarves still around in the far future of Men’s history?

  • The texts don’t say; later ages are written from the viewpoint of Men, and by that time Dwarves, Elves, and Hobbits are largely absent from their recorded history.

TL;DR
The Dwarves fight their own northern war during LOTR, survive, and then enjoy a last resurgence—helping rebuild kingdoms, prospering under kings like Thorin III and Durin VII, and even retaking Moria—before their people slowly dwindle in the Age of Men until they pass out of the world’s story.
