Ishval Civil War (Earth-1056)

The Ishval Civil War, also known as the Ishvalan War of Extermination, was a major conflict that saw the persecution and near extermination of the people of Ishval carried out by Amestris. Among the few survivors of the conflict was Carla Yeager, mother of Eren Yeager. The outrage over the destruction of an entire culture led the other four of the five great nations to declare war against Amestris, starting the First Great World War.
