Attack On Titan: The Eldia-Marley Conflict, Explained

Engaged in a centuries-long conflict that began as a battle between rival tribes which swiftly escalated into an all out war between empires, hostilities between the nations of Eldia and Marley have been responsible for most of the tragedies that have befallen the main cast of Attack on Titan. Long before the fall of Wall Maria at the start of the series to the assault on Liberio, and finally, the horrors of the Rumbling, the two nations had been at odds for virtually all of recorded history, perpetrating atrocities against one another that fueled a generational cycle of hatred. In the end, the unwitting protagonists of Attack on Titan found themselves embroiled in this conflict simply by virtue of their birth, with little idea of whether their side was in the right or not.
