Dunlendings, also known as Wildmen of Dunland, were the people of Dunland. They were known as a fierce culture of Men who sought vengeance on the people of Rohan who, as Saruman rightly said, drove them into the mountains. Though, not all Dunlendings never carried vengeance against Rohan. Some rebelled against Saruman and succeeded in taking back their land during the War of the Ring.
