Angmar was founded in T.A. 1300 in the far north of the Misty Mountains by the evil Lord of the Ringwraiths, who became known as the "Witch-king of Angmar". Since the Witch-king was a servant of the Dark Lord Sauron, it is presumed that Angmar's wars against the successor kingdoms of Arnor were done at Sauron's bidding to destroy an important ally of Gondor.
