Rhudaur formed the eastern part of Arnor, and stretched from the Weather Hills with Amon Sûl to the river Bruinen. It reached to the Ettenmoors. It shared a long border with Cardolan along the East Road, and with Arthedain along the line of the Weather Hills.
From the start of its existence, Rhudaur was unfriendly towards the two other successor states, and took part in a bitter conflict with Cardolan over the tower of Amon Sûl and the Palantír associated with the tower.
By around T.A. 1349 a lord of the Hill-men had seized power and had secretly allied with Angmar; few Dúnedain remained in Rhudaur and the only remaining descendant of the House of Isildur was the King of Arthedain Argeleb I. As Heir of Isildur Argeleb claimed the lordship of all former Arnor which the lord of Rhudaur resisted. In 1356 Rhudaur and Angmar attacked the Weather Hills, and Argeleb was killed. It was because of this hostile nature of Rhudaur that the Stoors fled, with some of them moving west to Arthedain, and others moving back to Rhovanion.
There is evidence that after the fall of Angmar at the Battle of Fornost the Angle became home to the remainder of the Dúnedain, and the Rangers of the North established several villages there,[source?] where their people lived until the resurrection of the northern Kingdom under King Elessar at the end of the Third Age.
