Angmar is a fictional realm in J.R.R. Tolkien's Middle-earth, primarily featured in "The Lord of the Rings" and its related works. It was established by the Witch-king, the leader of the Nazgûl, during the Third Age. Angmar is known for its dark and foreboding landscape, characterized by mountains and cold, desolate regions. The kingdom of Angmar sought to conquer the northern lands, particularly the Kingdom of Arnor. Its forces were eventually defeated in the year 1975 of the Third Age, leading to the fall of the Witch-king and the end of Angmar's threat to Middle-earth.
