Witch-king of Angmar

The Witch-king is a fictional character created by J. R. R. Tolkien, the chief of the Ringwraiths of Middle-earth.

The Witch-king was originally a Black Númenórean lord. In the Second Age, he was given one of nine Rings of Power to help rule over his realm. He and eight others were ensnared by Sauron, who made them the Nazgûl. He became the lord of the Wraiths, and Sauron's chief servant. He later founded the realm of Angmar, and then besieged and took Minas Ithil, renamed it Minas Morgul, and became its lord. Eärnur, King of Gondor, who had previously routed the Witch-king from Arnor at the Battle of Fornost but at the last moment dared not face him (At which point the Noldorin elf Glorfindel the prophesied to Eärnur that no man would slay the Witch King), accepted his challenge to meet him in single combat in Minas Morgul, and never returned. From that day until the coronation of Elessar hundreds of years later, Gondor was ruled by a Steward, as there was none to claim the kingship.

He led the search for the One Ring, and later Mordor's assault on Minas Tirith. Here he was slain by Théoden's niece Éowyn with the aid of the hobbit Meriadoc Brandybuck, thereby fulfilling the prophecy that no man should slay him.
