The March of Maedhros was an Elven realm in the eastern Beleriand between Dorthonion and the Blue Mountains (Ered Luin) next to his younger brother's domain. It consisted of a series of hills and plains.
The March of Maedhros was fortified by Maedhros after he moved his brothers and their people out of Hithlum further east to avoid any feuds with their kinsmen. He established himself on the Hill of Himring. It withstood the frequent attacks by the forces of Angband throughout the First Age, standing strong in the Battles of Beleriand including the ravages of the Dagor Bragollach (Battle of Sudden Flame). It was finally overrun during the Nirnaeth Arnoediad (Battle of Unnumbered Tears) in FA 473.
