Hajime Isayama opens up about the history of oppression and colonization depicted in Attack on Titan through Marley and Eldia.

Attack on Titan deals with several dark concepts and while gore is what stands out at first, it eventually turns to other social issues as well. Hajime Isayama designed Attack on Titan after the extremely real problems of the world such as colonization, slavery and more.

The cruel treatment of the Eldians at the hands of the Marleyans can boil anyone's blood. However, the history of colonialism did not begin with Marley because Eldia's expansionist policies were also equally disruptive.

In an interview with Crunchyroll News, Hajime Isayama opened up about the nitty-gritty details of Attack on Titan. The author was asked what language the characters in the anime communicate in. The author replied that the characters speak in a language that can be called the universal language in the world of Attack on Titan.
