The Akaneian League (Archanean League in North America) is the army led by Marth against the armies of Doluna during the War of Darkness. The Akaneian League consists of the nations of Altea, Talys, and Aurelis, in addition to the main continent of Akaneia. The goal of the Akaneian League is to liberate Akaneia from the Shadow Dragon Medeus. After Marth meets Hardin and Princess Nyna in Aurelis, she asks Marth to lead the Akaneian League, and gives him the Fire Emblem.

Elements of the enemy nations Grust and Medon would also end up joining the league.
