A timeline of all events from the Attack on Titan anime.
Prehistoric events are followed by "B1," indicating that they predate Year 1 of the given calendar system used in the Attack on Titan world. Historical events and story events preceded by "c." are approximations based on given information and are not to be considered exact dates, and may be subject to change as new information is given.
|1003 B1||Ymir Fritz made a contract with the Devil of All Earth and obtained the power of the Titans.|
|c.254||A deadly plague swept through the whole world, but the Eldian Empire was relatively unaffected, due to the power of the Founding Titan which altered the bodies of Eldians.|
|Unknown||Eldia becomes allies with Hizuru.|
|Unknown - c.743||The Great Titan War - Karl Fritz, the 145th monarch of the Fritz family, inherits the Founding Titan and succeeds his predecessor as the monarch of Eldia. Ashamed of Eldia's history of genocide and civil war, Fritz conspires with the Tybur family, an Eldian house possessing the War Hammer Titan, to bring about Eldia's downfall.
Karl Fritz gathers most of the Fritz royal family to Paradis Island, Eldia's last remaining undisputed territory, abandoning the conflict between the eight other Titan houses. He also invites Asians from the Shogun clan of Hizuru. Some Fritz royals disagree with the King's decision to abandon the war, and remain behind in the mainland. In the King's absence, the other eight Houses wage civil war.
The surviving Marleyans took advantage of this and incited a rebellion. The Tybur family is the first to side with the Marleyan uprising.
Over the course of the war, the Marleyans succeed in gaining the power of six more of the Nine Titans possessed by Eldia: the Colossal Titan, the Armored Titan, the Female Titan, the Beast Titan, the Cart Titan, and the Jaw Titan.
Using the seven Titans, Marley gradually gains control of the continent.
|c.743||In order to stop the war, King Fritz sends a false message to the people of Marley, demanding that the surviving Eldians must be left alone or the Colossal Titans will "flatten the entire Earth."The Great Titan War ends. The nation of Marley would retain control of a large portion of the world beyond Paradis Island throughout the next century, using the power of the Titans. Hizuru's reputation is tarnished due to their association with Eldia.
The Eldians who did not flee overseas would become low-class citizens of Marley, forced to live in internment zones separate from the rest of the population, and are marked with distinctive armbands denoting their status; black-yellow for civilians, light blue for soldiers, yellow for Warrior candidates, and red for Warriors and their families.
After gaining control over the mainland, the Marley government promotes the story that Ymir Fritz had gained the Titan's power through a deal with the "Devil of All Earth," who was slain by their hero Helos during the war.
King Fritz informs both the Fritz family in Marley and the Tybur family that he has made a vow renouncing war to the Founding Titan, and that there will be no retaliation if and when Marley chooses to enact a final solution against Eldia. However, he asks that he and his people should be given a brief age of peace before their retribution. The King uses the power of the Founding Titan to erase the memories of the Subjects of Ymir. The Subjects successfully forget their history, but minority groups not sharing the majority's common bloodline such as the Ackermann clan and the Asian clan are unaffected by the mind wipe. Many of the minority groups swear to secrecy at the King's request and gain noble status, but the Ackerman and Asian groups give up said status, turn against King Fritz, and are hunted down.
The 145th Fritz King, now the First Reiss King, creates an underground cavern where the Founding Titan can be passed down to successors within the royal family. Some time afterward, a chapel is built above the entrance to the cavern.
