I have seen that timeline in AoT is kinda confusing for people, and it’s quite understable.

From the beginning of manga to RtS, each event happened right after the other one, and the timeline was very easy to understand.

But then we had a 4 years timeskip.. Or 3 years? 4 years after “Return to Shiganshina”, but 3 yeas after the Survey Corps arrived to the sea.

And thanks to that timeskip now we have like a ton of flashbacks we must organize and join the pieces.

Of course, there is the fact that we must wait 1 month before reading a new chapter, so, Sasha died 2 years ago in our real time, but in AoT timeline it happened just a month ago!!

So I wanna make the AoT timeline as clear as possible in this thread.

2000 years ago

Ymir (the founder) was hunted by King Fritz’s soldiers, fell inside a big tree, and that spine gave her the power of the titans.
