Angmar was founded around T.A. 1300 by the Witch-king, the Lord of the Nazgûl. An evil realm, it lay nestled in and along the icy flanks of the northern Misty Mountains (S. "Hithaeglir"), in the high plateau of northeastern Eriador. Between T.A. 1301 and 1974, Angmar warred on Arthedain, Cardolan, and Rhudaur, the three Dúnadan successor states to old Arnor.
