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.


Year Event
743 Titans appear across the world for the first time in history, beginning a mass slaughter of the human race.[1] Through unknown means, countless Colossal Titans are gathered together to form three massive barriers by hardening their skin. The surviving remnants of humanity escape to these three barriers, the Walls Maria, Rose, and Sina.[2][3] Evidently, some human settlements survive beyond the Walls.[4][5]

Along with the majority race within the Walls, a clan from a place known as the "Orient" successfully enters into the Walls.[6]

c.780 A homeless girl from beyond the Walls is given the name "Ymir" by the leader of a cult, the "Subjects of Ymir." The girl joins the cult and becomes a figure of worship.[5]
784 A miner attempts to dig beneath Wall Sina to enter the interior, but after digging for some time he discovers an area below the ground where the Walls jut outward. After discussing his findings with a friend, the miner mysteriously disappears, and his friend disappears as well soon afterward.[7]
c.785 The Subjects of Ymir are found by the authorities. They are led through the streets in chains and are exiled a remote borderline where they are all turned into mindless Titans wandering the wilderness.[5]
c.830 Grisha Jaeger cures a devastating plague in Shiganshina District.[8]
835 Mikasa Ackermann is born to Mr. and Mrs. Ackermann, the latter being the last member of the Oriental clan.[6][9]

Eren Jaeger is born to Grisha and Carla Jaeger.[9]

844 Nicholas Lovof tasks Levi, Furlan Church, and Isabel Magnolia to find incriminating files on Lovof's business with Lang Company and to kill Erwin Smith, who carries the files. Erwin Smith encounters Levi in the Underground and offers to pardon his crimes if he joins the Scout Regiment.[10]

Commander Keith Sadies decides to finally implement Erwin Smith's scouting formation into the 23rd Exterior Scouting Mission. On this expedition, Furlan and Isabel are killed by an abnormal Titan. Erwin convinces Levi to fight for the Scout Regiment after Levi nearly takes Erwin's life.[11]

In her home, Mikasa Ackermann is abducted by human traffickers after her parents are killed. She is rescued by Eren Jaeger, who kills two of the traffickers. Mikasa manages to kill the third in a moment of fury. She is later taken in to the Jaeger family.[6]


Time Event
845 Grisha Jaeger travels to the interior, promising to show his son Eren the secret within his basement upon his return.[8]

A settlement beyond the Walls sends out four of their Warriors, Bertholdt Hoover, Reiner Braun, Annie Leonhart, and Marcel to destroy humanity and retrieve the "Coordinate."[12][5] Marcel is eaten by Ymir's Titan, and Ymir regains her humanity.[5]

Bertholdt as the Colossal Titan breaches the outer gate of Shiganshina District,[8] allowing Titans supposedly drawn in by Annie as the Female Titan to enter into the city and starting the fall of Wall Maria.[13] Carla Jaeger is eaten by a smiling Titan.[8] Reiner as the Armored Titan breaches the inner gate. Humanity is forced to retreat to Wall Rose. Eren Jaeger vows to exterminate the Titans.[2]

Grisha reunites with Eren and injects him with a serum which erases parts of his memory while also presumably giving him the ability to turn into a Titan. Grisha then disappears.[14]

The Reiss family proposes killing off Historia, an illegitimate child of the head of the family, to clear up the matter of inheritance. It is instead decided that she will live a humble life under the new name "Christa Lenz" in the Cadet Corps. Ymir overhears this news in a conversation between priests in the Order of the Walls, and she begins a search for Christa.[15][5]

846 The central government enacts a culling in the form of a Wall Maria reclamation operation, sending out 250,000 civilian troops, around twenty percent of the surviving human population. Less than two hundred return alive.[2]
847 The 104th Cadet Corps begins.[2]
848 During a wilderness training exercise, Christa Lenz is nearly captured by bandits. The cadets team up to take down her captors, and they successfully rescue Christa.[16]
849 On the 34th Exterior Scouting Mission, Ilse Langnar encounters a Titan who speaks of the "Subjects of Ymir" and "Lady Ymir." She attempts to communicate with the Titan but is eventually eaten.[17]

In order to settle an argument among cadets Jean Kirschtein and Sasha Braus, Garrison Commander Dot Pyxis hosts a cook-off. Sasha presents cooked meat while Jean presents an omelette cooked by his mother, and Jean is declared the victor.[18]

Armin Arlelt vouches for Eren's life to Garrison Captain Kitz Woermann. Commander Dot Pyxis arrives in Trost and collaborates with Armin in a plan to take back Trost with Eren's Titan.[23] After announcing the operation plan to the soldiers of Trost, Eren accompanied by the Garrison elite soldiers travels to a boulder within the district in order to seal the breach.[24]

Eren's Titan temporarily loses control and incapacitates itself, but is revived when Armin speaks to Eren directly through the nape.[25] Using the boulder, Eren closes the breach and Trost District is saved.

Annie disrupts the expedition as the Female Titan, invading the right flank of the expedition to search for Eren. After finding Armin and sparing his life, Armin, Reiner, and Jean attack her to stall for time on Eren's behalf,[13] but Reiner secretly informs her of Eren's true location in the expedition formation.[12]. She is nearly captured when Commander Erwin leads the Scouts into a Forest of Giant Trees with special target restraining weapons on standby.[30] Using her shriek to attract Titans to her[32], she escapes the Scouts' capture and kills four members of the Special Operations Squad.
