Broadcast order is chronological order. There are no timeline jumps that justify changing the sequence. Start from the beginning and watch in order:

The three Walls of Paradis echo Japan's own historical isolation policy known as sakoku (locked country), in effect from 1633 to 1853. The outside world was forbidden; citizens were sealed in by policy and fear. When the titans breach the walls, it mirrors the moment American ships broke Japan's isolation in 1853 — a traumatic rupture of the familiar world.
Attack on Titan deliberately engages with questions of generational guilt, cycles of violence and the moral weight of inherited conflict — themes deeply relevant to Japan's own reckoning with World War II. The series refuses easy answers, showing how every side has victims and perpetrators.
The Survey Corps functions as a kind of modern samurai order: absolute loyalty, willingness to die for the mission, and the bushido-adjacent idea that a meaningful death serving others is the highest calling. Levi's character embodies this code most explicitly.
4 seasons: Season 1 (2013, 25 eps), Season 2 (2017, 12 eps), Season 3 Parts 1+2 (2018–2019, 22 eps), Season 4 The Final Season including Final Chapters (2020–2023).
The No Regrets OVAs (Levi's backstory) are highly recommended. Lost Girls adds depth to Annie and Mikasa. Compilation films can be skipped — same content as the series.
Crunchyroll has the full series. Netflix carries most seasons. Amazon Prime Video covers some seasons depending on region.
