The saga of Attack on Titan is anchored by the long and brutal history of the Eldian people. For those teaching or studying the series, mapping out this timeline is essential—it provides the ideological and political bedrock upon which every character’s motivation is built. This comprehensible overview unpacks the key eras, turning points, and figures that define the Eldian experience from the age of myth to the modern conflict.

The Mythic Origins: Ymir Fritz and the Source of All Titans

The Eldian race traces its lineage to a single tragic figure: Ymir Fritz. Over two thousand years before the main story, Ymir was a slave to the ancient Eldian tribe, which was itself subjugated by a rival group. After being blamed for a crime she didn't commit, she fled into a forest and stumbled upon a massive tree containing a mysterious, spine-like entity—the so-called “source of all living matter.” Her fusion with this organism transformed her into the first Titan and the most powerful being in existence.

For thirteen years, Ymir used her unprecedented might to serve King Fritz, the man who had originally enslaved her. She built roads, cultivated wasteland, and crushed the kingdom’s enemies, all while bearing the king’s three daughters: Maria, Rose, and Sina. Her servitude ended when she threw herself in front of an assassin’s spear meant for the king. In a desperate attempt to keep her power alive, King Fritz mutilated her body and forced his daughters to consume her flesh, an act that would distribute the “Titan power” across multiple inheritors for generations to come. This macabre ritual established the rule that only those of Ymir’s bloodline—what we now call Subjects of Ymir—could become Titans, and that a Shifter’s power would be passed on by cannibalization.

Ymir’s consciousness became trapped in a timeless, sand-swept dimension known as the Coordinate, where she was compelled to obey the royal Fritz bloodline unquestioningly, crafting Titans out of magical soil for eternity. This metaphysical prison explains why the Founding Titan’s will has always been bound by the king’s ideology until the rise of Eren Yeager.

Rise of the Eldian Empire: The Great Titan War

With the original Titan’s power fragmented among her three daughters, the Fritz family split into multiple noble houses that passed down their abilities. Over centuries, the Eldians weaponized the Titans and conquered much of the known world, establishing an empire built on the suffering of subjugated peoples, most notably the nation of Marley. During this era, the nine distinct Titan Shifters emerged, each possessing a unique aspect of Ymir’s original form: the Attack Titan, the Colossus Titan, the Armored Titan, the Female Titan, the Beast Titan, the Jaw Titan, the Cart Titan, the War Hammer Titan, and the Founding Titan itself.

Eldia’s prosperity was built on the back of what modern scholars would call ethnic cleansing. The empire forcibly displaced and interbred with conquered populations, spreading the Subject of Ymir gene across the continent while simultaneously maintaining a strict class system. The Marleyan people, reduced to a servile underclass, bided their time. Around the 8th century after Ymir’s death, a civil war known as the Great Titan War erupted when rival Eldian noble houses—each holding a Titan power—turned on each other. Marleyan insurgents seized the chaos to orchestrate a massive uprising, systematically capturing seven of the nine Titans. The War Hammer Titan (held by the secretive Tybur family) secretly sided with Marley, and the 145th Eldian King, Karl Fritz, fled to the remote island of Paradis with his people and the Founding Titan, effectively ceding the mainland.

The Vow of King Karl Fritz

King Karl Fritz was a figure of immense contradiction. Tormented by the sins of his ancestors, he saw the Eldian Empire as irredeemably evil and believed his people deserved eventual extinction. When he retreated to Paradis, he used the Founding Titan’s power to erect three colossal concentric walls—Wall Maria, Wall Rose, and Wall Sina—by commanding thousands of Colossus Titans to harden their skin. He then used the Founding Titan’s coordinate ability to erase the memories of the Eldians within the walls, leaving them with the false belief that humanity had been driven to the brink of extinction by the Titans and that they were the last survivors.

Most crucially, King Fritz imposed upon the royal bloodline a Vow Renouncing War. Any future inheritor of the Founding Titan who possessed royal blood would be overcome by the king’s pacifist ideology and become unable to use the Titan’s full power, even for self-preservation. This guaranteed that even if Marley invaded, the Eldians of Paradis would meekly accept their annihilation as penance for their forebears’ crimes. The Vow held for a century until it was challenged by the Yeagerists.

The Marleyan Supremacy and the Fall of Eldia

With the Eldian king in hiding, Marley officially declared victory and set itself up as the dominant world power. The captured Titan Shifters were carefully integrated into a military hierarchy, and Marleyan propaganda rewrote history to paint Eldians as devils who had once “ruled the world through the terror of the Titans.” The mainland Eldians who remained behind were forcibly relocated to designated ghettos known as Liberio Internment Zones. There, they were stripped of citizenship, required to wear identifying armbands, subjected to brutal medical testing, and exploited as military weapons when their children were conscripted into the Warrior program.

The Tybur family, though Eldian, was elevated to a special status as heroes for supposedly aiding Marley’s rebellion. In truth, they perpetuated a massive lie: that King Fritz had been a heroic peacemaker who fled to Paradis because he couldn’t stop the other Eldian houses from waging war, when in reality he had fled out of shame and left the rest of his people to suffer. This narrative allowed Marley to frame its imperial ambitions as righteous retaliation while keeping the world’s hatred focused squarely on the Eldian race.

The Walls of Paradis and the Onset of Isolation

On Paradis, the Subjects of Ymir lived for a hundred years in blissful ignorance. The royal government, secretly controlled by the Reiss family (the true Fritz descendants), operated a police state through the Interior Military Police and the First Interior Squad, assassinating anyone who ventured too close to the truth. The Survey Corps, initially founded to explore beyond the walls and find hope, was deliberately hampered and fed suicidal missions to keep the population afraid and submissive. The massive Titans wandering outside the walls were, in reality, mindless Eldian criminals and political dissidents forcibly transformed by Marley and sent to the island as weapons of punishment.

This equilibrium began to crack with the rise of Grisha Yeager, a former Eldian restorationist from Liberio, who infiltrated the walls and usurped the Founding Titan from the Reiss family. Grisha’s subsequent possession by his son Eren triggered a chain of events that would eventually expose the entire global conspiracy.

Key Historical Figures Shaping the Eldian Destiny

The Eldian timeline is punctuated by individuals whose choices redirect history. Here are the three most pivotal:

  • Ymir Fritz: As the progenitor, her unresolved trauma and enslavement to the Fritz bloodline created the very conditions of servitude and the “Paths” dimension that binds all Subjects of Ymir. Her eventual liberation by Eren is the series’ climax.
  • King Karl Fritz (145th King): By constructing the Walls and enacting the Vow Renouncing War, he sealed the fate of twenty million Paradis Eldians. His ideology of self-hatred bled into later figureheads like Rod Reiss and kept the island stagnant for a century.
  • Zeke Yeager: Born of royal blood through Grisha’s first marriage, Zeke became the inheritor of the Beast Titan and the architect of the “Euthanasia Plan.” His tragic belief was that Eldians could only be saved by sterilizing themselves so that no future generations would suffer from the cycle of hatred. Zeke’s betrayal of his parents, his cooperation with Marley, and his secret alliance with Eren form the central tension of the final arcs.

The Attack Titan’s Unsung Role

While the Founding Titan gets most of the lore attention, the Attack Titan—a Shifter that has always fought for freedom—played a covert role in Eldian history. Uniquely, the Attack Titan’s future inheritors can send memories backwards in time to their predecessors. This ability allowed Eren to subtly influence the past, ensuring that his father Grisha would murder the Reiss family and seize the Founding Titan. The Attack Titan’s independence from royal control made it the one piece on the board that could ever truly oppose the Vow Renouncing War.

The Modern Era and the Cycle of Hatred

In the present timeline of Attack on Titan, Eldians live under a global regime of apartheid. Even nations not directly conquered by Eldia, such as Hizuru, treat Subjects of Ymir with suspicion. Marley’s military expansion relies heavily on the Warrior Unit—young Eldian conscripts who are promised honorary citizenship for their families in exchange for mastering the Titan Shifters and waging war against other countries. This institutionalized exploitation mirrors real-world historical patterns of using marginalized peoples as foot soldiers, making the story a potent allegory for themes of discrimination, generational trauma, and militarized oppression.

On Paradis Island, the discovery of Grisha’s basement knowledge shatters the walled worldview. The Royal Government was overthrown, and the Survey Corps reached the ocean, only to find enemies in every direction. Eren’s realization that “beyond the sea, there are enemies; and beyond those enemies, even more enemies” led him to a radical solution: the Rumbling, a planetary-scale genocide using the thousands of Colossus Titans sleeping within the walls.

This act, while abhorrent to many, flows directly from the historical analysis. The world had never once attempted to understand Paradis’s Eldians as anything other than devils. Delegations like the Scouts’ mission to Marley were met with calculated hostility. The cycle of hatred—Marley abuses Eldians, Eldians retaliate, the world unites against Eldians—proved inescapable through conventional diplomacy. Eren’s decision, therefore, is not a sudden villain turn but the culmination of 2,000 years of entrenched bigotry.

The Internment Zones and the Struggle for Identity

Life in Liberio and other internment zones is a masterclass in psychological subjugation, as detailed lore analyses explain. Eldian children are forced to learn a state-sanctioned history that casts them as the descendants of criminals. The Honorary Marleyan program dangles false hope, encouraging families to betray underground restorationists. Yet even in this darkness, figures like Grisha Yeager and the Owl (Eren Kruger) formed the Eldian Restoration Movement, keeping the flame of cultural pride alive. The Restorationists believed that the only way to achieve dignity was to reclaim the Founding Titan and liberate Paradis—a belief that Eren ultimately twisted into a global annihilation order.

Implications for Educators and Students

For classroom discussions, the Eldian timeline offers a rich framework to explore difficult topics. The Great Titan War can be used to discuss how history is written by the victors and how propaganda dehumanizes the “other.” The Vow Renouncing War parallels historical peace movements that prioritized ideological purity over practical survival. And the Euthanasia Plan proposed by Zeke forces a debate on whether a persecuted group’s suffering can ever justify self-erasure.

Further reading on the ethical dimensions of the Eldian crisis can be found in thoughtful fan analyses and the in-depth breakdowns that accompanied the series finale. These resources demonstrate that the Eldian timeline is not just a fantasy chronology but a mirror reflecting real-world cycles of violence, radicalization, and the desperate human need for belonging.

Conclusion: History as a Weapon

Understanding the Eldian history timeline transforms how we watch Attack on Titan. Every wall, every Titan transformation, and every betrayal is a direct consequence of events stretching back millennia. The story ultimately argues that when history is weaponized to justify oppression, the only path toward a different future is to shatter that history entirely—or to transcend it. As the final chapters of the saga suggest, even the most earth-shattering act of violence cannot easily uproot the prejudices that have been cultivated for two thousand years. The Eldian experience, therefore, stands as a powerful warning about the cost of letting the past dictate the future.
