Easternmost of the three sections of Arnor, Rhudaur is the wildest, most rugged, and least populated region in the North Kingdom. When Arnor is sundered in T.A. 861, Rhudaur becomes an independent realm. It is a culturally diverse and politically volatile territory with a relatively small Dúnadan population. Hillmen (Hi. "Ne Dreubhan") and later, migrating Dunlendings, form the majority of its populace. Its sparse Dúnadan aristocracy loses control of the kingdom in T.A. 1349; in the following year Rhudaur goes to war with Cardolan and Arthedain. Rhudaur is subject to the Witch-king of Angmar for the last sixty years of its existence as a distinct state, until T.A. 1409. Thereafter Kings of Rhudaur are Angmarean puppets, ruling only the area around the capital at Cameth Brin.
