The Complete Timeline of Attack on Titan

  • Key:

“B1” – Before Year 1 of the AoT calendar system
“c” – Historical events that do not have exact dates

1. B1 1003: The Original Founding Titan

Once upon a time, there was a savage tribe composed of people called the Eldians. The Fritz clan were the rulers of the Eldians, who raided and captured slaves from opposing communities.

One of these slaves was a girl called Ymir who got into some trouble opening a pig enclosure. She runs away to escape Fritz’s men, and encounters the Devil of All Earth – the source of all living matter.

She makes a contract with him and gains the Power of the Titans, becoming the original Founding Titan, and the progenitor of the Eldian race as we know it.

2. B1 990: The 9 Titans And The Paths

When Ymir dies to save Emperor Fritz, she discovers the Paths, which are the invisible channels that connect the Titans and the Subjects of Ymir.

Ymir’s soul is split into 9 Titans; the Founding Titan can be inherited by descendants of the Royal Blood since the Emperor feeds Ymir’s corpse to his 3 daughters, and the other 8 by lesser Eldian houses or families.

The Titans are capable of regeneration but are destined to die at 13, just like she did. This is the Curse of Ymir.

3. B1 370: Eldia vs. Marley – The Fall Of Lago, Monte, And Valle

The Eldians begin their process of ethnic cleansing using the power of the Titans. Hundred and thousands of the Marleyans are killed.

4. c. B1 240: The Plague

When the epidemic strikes, half the world’s population was wiped off; it affects everyone except the Empire of Eldia, due to the power of the Founding Titan.

5. Early 700s: the Allies of Eldia

After a huge time-skip, we see that Eldia has allied with Hizuru, the shogun of which is the ancestor of the Ackermans. The Ackerman clan was actually created through human experimentation of Titan biology.

Due to their enhanced abilities, they became the monarch’s right-hand, capable of awakening their powers to protect members of the Royal Blood. (This is where Eren gets his theory that Mikasa is only devoted to him because of her inherited Ackerman gene.)

6. c. 743: The Great Titan War

The 145th Eldian monarch, Karl Fritz, has inherited the Founding Titan. He’s basically a good guy, who starts reflecting on Eldia’s bloody history of genocide.

He makes a deal with the Tybur Family, the house of Eldia possessing the War Hammer Titan, to end Eldia’s cruel reign.

The Tybur family gets down to business by fabricating myths. They spread the story of a Marleyan martyr called Helos to incite the Marleyans to fight against the Titans.

Fritz retreats with a few of his followers to the island of Paradis, the last of Eldian territory. The Marleyans gain control of 6 of the 9 Titans – the Colossus, the Armored, the Female, the Beast, the Cart, and the Jaw Titans.

Since Tybur sides with the Marleyans, they also have the War Hammer Titan. With the power of 7 Titans, the Marleyans win the war.

To protect the remaining Eldians, Fritz uses the Founding Titan to create 3 concentric walls named after the first Emperor’s daughters – Maria, Rose, and Sheena.

He tells the Marleyans that if the surviving Eldians are not left alone, the millions of Titans standing dormant within the walls – the Wall Titans – would destroy the planet. (This is the Rumbling that Eren and Zeke initiate later.)

Fritz also wipes the memories of the Subjects of Ymir but some clans that didn’t share the Eldian bloodline, like the Ackermans, still remember history and turn against Fritz.

Fritz and the royal family go under hiding and live as the Reiss family, but still retains the Founding Titan. He also takes a vow that prohibits any future inheritor of the Founding Titan to go against his pacifist will of renouncing war.

Meanwhile, the Marleyans spread the propaganda that the source of all evil was Ymir and that it was because of her that they had suffered genocide.

The remaining Eldians grow ashamed of their past and become indebted to the Marleyans for showing them mercy. They become devout followers of Marley.

Anyone showing disobedience are threatened to be transformed into Pure Titans and being sent to Paradis.

Eren meets with Mikasa and Armin where he tells them that they are mere slaves and the discussion gets heated. Eren gets both of them thrown into prison.

The Yeagerists, who are the rebels from the Paradis military along with civilians, want to reunite Eren and Zeke and help activate the Rumbling. They give everyone who consumed Zeke’s spinal fluid black armbands.

Yelena visits the soldiers and explains Zeke’s euthanasia plan to grant salvation to the Eldians. This would entail obliterating all the Eldians in Marley as well as Paradis using the powers of the Founding Titan, and render them infertile so the race itself dies out.

Eren in his Titan form rushes towards Zeke when he is decapitated by Gabi. Zeke catches his head before Eren dies and transport them to the Paths Realm. This is when things are fully explained – to us and to Eren.

He tells him about Ymir Fritz who lives in this realm, and how she has the ability to control all the Titans and every one of their descendants.

Unfortunately, she to is a slave, without a will of her own, since she has to obey the ones with the Royal Blood, whom she thinks are her masters.

This is also where Eren reveals to Zeke that he never intended to follow his euthanasia plan and tries to access the full power of the Founding Titan through Ymir but to no avail.

It is Zeke that has the power, and he uses this power to access their father Grisha’s memories, through Eren’s Attack Titan.

Zeke realizes that Grisha hadn’t brought Eren up to brainwash him and instead, it was in fact Eren that influenced his father to kill the Reiss family. Grisha is able to converse with Zeke and tells him to stop Eren.

The moment of realization: the past and the future was always meant to have happened the way that it did, the moment when Eren touched Historia’s hand 4 years ago.

Eren actually saw the actions of his future self and could thus follow in his future footsteps.

Eren gleans Ymir’s past and sees through her memories that she leads a life of fear, slavery, and torture. He asks her for the strength to destroy the world beyond Paradis and promises her freedom. Ymir gives Eren the full power of the Founding Titan.

In the real world, the Devil/Creature/Source of All Living Matter fuses with Eren and he becomes a Titan so massive and powerful that he looms over the entire city. And thus begins the Rumbling.

He promises them that they will still retain their free will, and that whatever they decide will happen.

On the flying boat, Falco can access memories of a former Beast Titan who had the ability to fly. Since he had ingested Zeke’s spinal fluid his Jaw Titan now has some characteristics of the Beast Titan. He takes flight with Annie and Gabi riding atop him

Eren reveals the ability to evoke dead Titans and summons Zeke’s Beast Titan from the past. Fort Salta is completely shattered.

All the other resurrected Titans overpower the Alliance but Armin and Zeke from the Paths Realm manage to reawaken the predecessors and ask them the lend their strength to fight the Founding Titan.

Levi decapitates Zeke and this stops the Rumbling. Jean detonates the explosives wrapped around the Founding Titan’s neck and the head is blown off; but the Creature tries to pull the body back together.

Armin emerges as the Colossal Titan and the Rumbling ends. But Eren is not dead yet.

The Founding Titan ejects a gas capable of converting people into Titans. Most of the Alliance are converted into Pure Titans.

Mikasa dreams of an alternate universe where she and Eren abandon everything and live happily ever after. But she wakes up to reality and knows what she must do.

She flies into the mouth of the Founding Titan, where Eren’s head hangs from its spine. She kisses him goodbye and severs his head, while Ymir watches.

She’s freed and all Titans disappear. Every Eldian affected by the Founding Titan’s memory manipulation, gain back their memories.

We are shown Armin’s heartbreaking conversation with Eren as his memories come back, how Eren explains why he had to do what he had to do, and that Mikasa had to give up her love like Ymir for the greater good.

Eren reveals his true feelings for Mikasa and entrusts Armin to save humanity.

This leads to plenty of tears and goodbyes. Mikasa also sees the spirit of Ymir Fritz before she’s finally put to rest.

The Eldians and the Marleyans realize that the Titans no longer exist, or will exist in the future.

33. c. 857: In the New World without Titans

3 years go by, and we see that Historia is living happily with her husband and child. 80% of the world’s population has been destroyed by the Rumbling and survivors begin peace negotiations between the two nations.
