At first glance, Attack on Titan appears to be a dark fantasy about towering man-eating giants and the soldiers who fight them. But beneath the surface of ODM gear and colossal transformations lies a deep, often unsettling reflection of our own history. Creator Hajime Isayama has woven real-world events into the very fabric of his narrative, using atrocity, rebellion, and cyclical violence to challenge what we think we know about humanity. To fully grasp the weight of Eren Yeager’s choices or the tragedy of the Eldian people, you need to understand the historical moments that inspired them. This exploration unpacks those connections, revealing why Attack on Titan endures as one of the most politically charged and morally complex stories of modern fiction.

The Real-World Historical Foundation of Attack on Titan

The Walls as Physical and Psychological Barriers

One of the most defining images of the series is the trio of concentric Walls—Maria, Rose, and Sina—that protect the remnants of humanity from the Titans. These walls serve as more than just plot devices; they are a direct allegory for the ideological barriers that have divided nations and peoples throughout history. The most potent parallel is the Berlin Wall, which sliced through Germany’s capital from 1961 to 1989, separating families, ideologies, and futures. When that concrete barrier fell, it symbolized not just the physical reunification of a country but the collapse of a repressive system that had told people they were safer inside. In Attack on Titan, the Walls similarly enforce a false sense of security, with the monarchy and military police feeding the populace a narrative of external threat to maintain control.

The psychological grip of the Walls mirrors the isolationist policies seen in feudal Japan during the sakoku period, when the country cut itself off from almost all foreign contact for over two centuries. Paradis Island’s inhabitants are taught that they are the last of humankind, a lie that prevents them from questioning the status quo. When the truth finally breaks through—that other nations exist, that they are despised for their ancestry, and that the walls are made of Titans—the resulting chaos echoes the societal shock that real communities experienced when long-standing cultural and political boundaries were suddenly dismantled.

World War II and the Scars of Global Conflict

The shadow of World War II looms heavily over Attack on Titan. The conflict between Marley and Eldia, with its tangled web of propaganda, victimhood, and aggression, mirrors the lead-up to and aftermath of the bloodiest conflict in human history. Marley’s rise as a militaristic superpower, its use of Titan-shifter weapons, and its systemic discrimination against Eldians recall the war machines of the Axis powers and the Allies’ own complicated moral footing. The series refuses to paint either side as purely righteous—a narrative choice that forces viewers to confront the uncomfortable truth that in war, the line between perpetrator and victim often blurs.

The Liberio internment zone, where Eldians are forced to wear identifying armbands and live in squalid conditions while being used as expendable soldiers, is an undisguised reference to the ghettos and camps of Nazi Germany. Yet Isayama doesn’t stop at a simple good-versus-evil dichotomy. He also shows how the Eldian Empire once brutalized Marley with Titan power, creating a historical grudge that fuels endless retaliation. This cycle of trauma and vengeance is a direct commentary on how nations like Germany and Japan grappled with their wartime legacies, and how historical narratives are weaponized to justify new atrocities. The series asks a terrifying question: when both sides have committed unspeakable acts, who gets to write the history books?

Totalitarianism and the Dangers of Unchecked Power

The oppressive machinery of the Marleyan government and the early puppet regime within the Walls both exemplify the hallmarks of totalitarianism. History’s most notorious dictatorships—from Stalin’s Soviet Union to Mussolini’s Italy—consolidated power by controlling information, silencing dissent, and creating an external enemy to unify the populace. Inside the Walls, the Royal Government hoards the truth about the outside world, memory wipes are used as a tool of control, and the Military Police Brigade kills anyone who gets too close to forbidden knowledge. The Reiss family’s decree that humanity must remain ignorant “for their own good” is a chilling echo of the paternalistic lies that real authoritarian regimes have told to justify censorship and brutality.

Marley, on the other hand, operates a slightly different brand of totalistic control. It maintains a global order through overwhelming military might and the institutionalized dehumanization of Eldians. The Warrior Program, which grooms children to become weapons of mass destruction in exchange for “honorary” status for their families, is a stark reminder of how fascist societies have historically co-opted youth, exploiting their loyalty and idealism. Gabi Braun’s indoctrination arc—where she fully believes Eldians are devils who deserve extermination—shows how easily a state can mold young minds to accept and propagate hatred. Her eventual, painful awakening is one of the series’ most profound arguments for the importance of education and exposure to the “other.”

Genocide and the Dehumanization of the Eldian People

No historical parallel in Attack on Titan is as harrowing—or as central to the plot—as the treatment of Eldians, which draws directly from the Holocaust and other genocides. From the armbands marked with the nine-pointed star to the forced relocation into designated zones, the imagery is intentional and visceral. But Isayama uses this parallel not just for shock value; he uses it to deconstruct the mechanics of mass murder. The series takes viewers inside the minds of characters like Grisha Yeager, who as a child was forced to watch his sister be mauled to death by Marleyan guards’ dogs for simply wandering outside the Liberio zone. That moment of radicalization, born from absolute powerlessness, sets off a chain of events that culminates in Eren’s own radicalization.

The Rumbling—Eren’s catastrophic decision to unleash the Wall Titans and trample the entire world—is the ultimate escalation of this theme. It poses a question that historical study often forces us to confront: does surviving genocide justify committing one? The series refuses to provide a comfortable answer. By showing us the world beyond the Walls, the diverse cultures and innocent lives that would be annihilated, Attack on Titan denies anyone the satisfaction of a clean moral victory. It’s a brutal reminder that the rhetoric of “us versus them” can mutate victims into monsters when trauma replaces empathy.

Colonialism, Nationalism, and the Cycle of Revenge

The power dynamics of the Attack on Titan world are also deeply rooted in the history of colonialism. The Eldian Empire’s centuries-long subjugation of Marley and other nations through the power of the Founding Titan is a fantastical stand-in for the imperial conquests of European powers in Africa, Asia, and the Americas. Eldia’s philosophy of “teaching the world a lesson” through Titan rule mirrors the civilizing missions that colonizers used to justify land theft, slavery, and cultural erasure. When Marley eventually overthrows Eldia and becomes the new dominant force, it does not dismantle the imperial system—it simply takes over, perpetuating the same violence in reverse. This pattern of oppressed-becoming-oppressor is a hauntingly accurate depiction of how colonial power structures often outlived the empires that built them.

Nationalism in the series acts as the fuel that keeps these cycles burning. Marleyan schoolchildren are taught a revisionist history that paints Eldians as subhuman, while Eldian restorationists cling to a mythologized past of Eldian greatness. Zeke Yeager’s euthanasia plan—a genocidal “mercy” that would eliminate Eldians from existence—is the tragic flower of this nationalist soil. It rejects the messy, difficult work of reconciliation in favor of a final, terrible solution. The series argues that nationalism, when left to fester, transforms historical grievances into permanent, self-justifying engines of destruction. No character fully escapes this trap, and that is the point.

Thematic Analysis: How History Echoes Through the Story

Freedom vs. Oppression – The Eternal Struggle

Eren Yeager’s single-minded pursuit of freedom is the series’ narrative engine, but it’s also its greatest philosophical provocation. From the moment we see him as a child staring at the Walls with burning intensity, he embodies the human desire to break every chain. This yearning resonates with actual revolutions, from the American and French revolutions to the Arab Spring. Yet Attack on Titan complicates the archetype of the freedom fighter. Eren’s definition of liberty is so absolute that it morphs into a monstrous thing—the freedom to destroy anyone who could ever threaten him. The series asks audiences to consider how many liberation movements, in their quest to throw off an oppressor, have recreated oppression in a new form. It’s a theme that lands with uncomfortable force in an era of global political upheaval.

The Moral Ambiguity of Humanity

At its core, Attack on Titan is an extended meditation on the nature of good and evil. Isayama deliberately obscures the line between heroism and villainy, forcing the audience to switch sympathies multiple times. Reiner Braun, the Armored Titan, begins as a traitor responsible for the death of thousands. But as we learn his story—the abused child soldier terrified of failure and desperate for approval—he becomes one of the most pitiable figures in the series. Conversely, Eren transitions from victim-hero to global terrorist. These reversals are not narrative tricks; they are the series’ thesis. Human beings are not born monsters. They are shaped by systems, histories, and choices. This echoes the findings of historians and psychologists who study perpetrator behavior in genocides and totalitarian states, where ordinary people commit extraordinary evil under the right pressures.

The Inescapable Cycle of Violence

“The world is cruel, but also very beautiful.” This line, repeated throughout the series, captures the duality that makes Attack on Titan so devastating. The story insists that violence begets violence with near-mechanical inevitability. Kaya, a girl whose mother was eaten by a Titan, later learns that the Titan was once a fellow villager. She must reconcile her trauma with the knowledge that her “monster” was a victim of a greater system. The series refuses to offer cathartic revenge. The final arcs, with their apocalyptic, continent-shattering battles, serve as a warning that without mechanisms for justice, truth, and reconciliation, societies are doomed to repeat the same massacres. The history of the 20th century—from the trenches of WWI to the nuclear bombings of WWII to the Rwandan genocide—proves that technological progress does not break this cycle; it only makes it deadlier.

The Price of Forgetting History

Throughout the series, knowledge is the most powerful and dangerous weapon. The Reiss family’s memory manipulation is a crime against humanity because it robs people of their agency to learn from the past. When Historia Reiss chooses to reclaim the truth and rule transparently, she breaks a chain that has strangled her people for a century. This insistence on remembering is a direct appeal to our own world, where Holocaust denial, revisionist textbooks, and the destruction of cultural heritage sites try to erase the darkest chapters of human behavior. Attack on Titan argues that the dead can only haunt us productively if we listen to their stories. Turning away is what allows the next genocide, the next wall, the next Rumbling to become thinkable.

Lessons for Our Time: What Attack on Titan Teaches Us

It would be easy to watch Attack on Titan and conclude that humanity is hopelessly broken. The show certainly doesn’t shy away from our capacity for horror. But buried beneath the ash and rubble is a stubborn, defiant hope. Scattered acts of mercy break through the despair—Armin’s refusal to let go of dialogue, Jean’s evolution from selfishness to leadership, and the quiet coalition of soldiers who cross factional lines to stop the Rumbling. These moments do not erase the bloodshed, but they suggest that the cycle can be paused, if not permanently broken.

The series’ real-world inspirations remind us that the walls we build—physical, ideological, or psychological—are always a temporary solution. They may keep out Titans for a century, but eventually, the truth will kick through the gate. The only lasting alternative is the difficult, uncomfortable work of confronting our shared history and seeing the face of an enemy as a reflection of our own. Hajime Isayama has given us a parable that will outlive its genre, not because it gave us answers, but because it asked the right questions with an honesty few fictional works have dared to summon.
