The story makes mention of how before the titans people used to fight each other constantly until the titans came along. The First King called the world within the walls "True Peace" and what I beleive he meant by that was in a world where humanity is trapped and surrounded by a threat of unimaginable power they would stop fighting each other and make an effort to live in peace. Hange questioned this idea by calling it "twisted" (I beleive the translation was something similar to this if this is not the exact translation). I beleive the First King's reason for removing humaity's memories was to make them forget their hatred for each other so they wouldn't even consider fighting each other within the walls.
