Witch-king of Angmar
The Witch-king of Angmar was originally a great king of Men. In the Second Age, he and eight other men were given the nine Rings of Power by the Dark Lord of Mordor, Sauron. The Rings gave them incredible power, which they used to further their own ambitions, but eventually the Rings completely corrupted them and turned them into the ghastly Nazgûl.
He founded the kingdom of Angmar. It is after the formation of Angmar and several conflicts with the Dúnedain of the North that the Lord of the Nazgûl became widely known as the Witch-king, Lord of Angmar, reflecting the fact that he practiced black sorcery. Because of the great havoc he wrought in the north, he became notorious among the peoples of Middle-earth as the terrible Lord of Angmar; thus, he thereafter retained his title of Witch-king, even long after he left Angmar.
