Dunlendings

The Dunlendings are a primitive peoples living in Middle-Earth as depicted in J.R.R. Tolkein's Lord of the Rings trilogy. They live near the people of Rohan but fear and hate them. Incited into violence by Saruman the White, the Wild Men join him and assist his Orcs and Uruk-hai in attacking the lands of Rohan and slaughtering their people. Eventually, Rohan's people become desperate enough to retreat to the refuge of Helm's Deep.

The fate of the Wild Men then differs depending on the version of the story: in the books, they assist the Orcs and Uruk-hai in attacking Helm's Deep. After the battle is lost, they are rounded up, and spared by the men of Rohan under the condition that they not rise up against them again. Touched by this display of mercy and honor, the Wild Men honor the agreement, and peace prevails.

Conversely, in the continuity of the movies, the Wild Men are not present at the Battle of Helm's Deep, having been earlier pounded by either mounted companies of men who patrol the lands of Rohan to keep them safe, or perhaps even the Rohirrim that had been mustered by Eomer and Gandalf the White. Either way, it would be the last time the Wild Men made a concentrated attack on Rohan's people. And as Rohan, Gondor, and other human kingdoms continued to prosper, the more primitive Wild Men dwindled and receded into the shadows until they were all gone.
