Attack on Titan (Shingeki no Kyojin) has become one of the most iconic anime series of the decade, known for its gripping storyline, emotional twists, and deep political intrigue. Whether you’re a long-time fan or new to the series, understanding the complete timeline helps make sense of the complex world and characters. In this guide, we’ll break down the entire Attack on Titan timeline from beginning to end — and along the way, we’ll also touch on the iconic Scout Regiment costume and how Attack on Titan costumes have influenced fan culture worldwide.
1. The Origin of Titans – 2,000 Years Ago
The story begins nearly 2,000 years before the main timeline, when Ymir Fritz became the first Titan after making a mysterious pact. After her death, her powers were split into the Nine Titans, which formed the foundation for centuries of conflict between Marley and Eldia.
This ancient history isn’t fully revealed until later in the series, but it sets the stage for the entire world-building of Attack on Titan.
2. The Great Titan War and the Founding of the Walls (Year 743)
Fast forward to several centuries ago: Eldia collapses due to internal strife and Marley gains power. King Karl Fritz, the 145th King of Eldia, takes the Founding Titan and retreats to Paradis Island. He creates three concentric walls — Maria, Rose, and Sheena — using Colossal Titans. The people inside the walls are led to believe they are the last of humanity.
This era marks the beginning of a false peace and isolation. It’s also when the legendary Scout Regiment (also known as the Survey Corps) is established, wearing their now-iconic Scout Regiment costumes, complete with cloaks and the Wings of Freedom emblem — a symbol of humanity’s hope.
3. The Fall of Wall Maria (Year 845)
The real story of Attack on Titan begins when Wall Maria is breached by the Colossal Titan and the Armored Titan. This leads to the tragic loss of protagonist Eren Yeager’s mother, and sets him on a path of revenge.
This pivotal event reignites the activity of the Scout Regiment, with Eren eventually joining and donning the same Attack On Titan scout regiment Erwin Smith cosplay costume fans have come to associate with courage and sacrifice. These Attack on Titan costumes have since become some of the most popular cosplay outfits at anime conventions.
4. The Titan Battles and Truth Revealed (Years 850–851)
During this period, many shocking truths come to light:
-
Eren is revealed to possess the Attack Titan
-
The identities of Reiner, Bertholdt, and Annie as enemy Titan shifters are exposed
-
The truth about the world outside the walls is discovered in Grisha Yeager’s basement
These revelations completely flip the series on its head. As the Scouts fight back, the story moves from survival horror to military and geopolitical warfare.
The Scout Regiment’s missions beyond the walls become even more dangerous — and symbolic. Wearing the Scout Regiment costume becomes more than a uniform; it’s a symbol of truth-seeking and resistance.
5. The Invasion of Marley (Year 854)
By now, Eren has taken a darker path. The Scouts infiltrate Marley, launching a surprise attack during a festival. This act escalates the conflict into all-out war between Paradis and Marley.
It’s also during this arc that characters like Mikasa, Armin, and Levi wear updated versions of their Attack on Titan costumes, reflecting their growth and the series’ shift in tone.
6. The Rumbling and the Final Battle (Years 854–857)
Eren unleashes The Rumbling, awakening countless Colossal Titans to trample the world. His aim: to destroy all enemies of Paradis Island.
This dark climax pits former friends against Eren. Mikasa and the remaining Scouts must make the ultimate choice. In the final episodes, we see emotional goodbyes, intense battles, and heartbreaking sacrifices.
7. The Legacy of Attack on Titan
After the dust settles, the world of Attack on Titan is forever changed. The series ends on a note that reflects on freedom, morality, and the cost of power.
As the anime concluded, the popularity of Attack on Titan costumes—especially the Scout Regiment uniform—surged once more. Fans across the globe continue to honor the series through cosplay, fan art, and storytelling.
Whether you’re dressing up in a Scout Regiment costume or simply revisiting the story, Attack on Titan leaves a lasting impression with its epic timeline and unforgettable characters.
