When Does Attack on Titan Season 4 Take Place?

The world of Hajime Isayama’s Attack on Titan is a truly special one. Whether you like the militaristic undertones or not, the world Isayama has created is undeniably unique. The manga is finished, and the anime is slowly nearing its end, but the world of the franchise still keeps attracting fans who wonder about its origin and its structure. In this article, we will tell you when the fourth season of Attack on Titan takes place.

The fourth season of Attack on Titan takes place over a relatively long period of time, starting in 850 and ending during the Rumbling in 854. The final episode will also probably show the epilogue of the series, which is set several years after the Rumbling. Season 4 will bring the series to an end and finish the chronology of Isayama’s lore in the best possible way.

The rest of this article is going to further explore the world of Isayama’s Attack on Titan, as we are going to introduce you to the timeline of the whole anime, focusing specifically on Season 4 of the anime, which is currently ongoing. This article might contain many spoilers for those who are not fully up-to-date with the series’ events, so be careful how you approach the article.

When does Attack on Titan take place?

Now, Attack on Titan follows a separate chronology that doesn’t connect to our regular timeline of historical events. Since the series has a lot of steampunk elements, it is very difficult to determine the historical period in which it could be set; there are some medieval elements to the show and many modern elements from the Industrial Age. This is why it is best for us to tell you about the franchise’s chronology rather than speculate and give you some misleading answers. This is how things went down in Attack on Titan:
