seaboigium reblogged your post “Timeline of Naruto Universe”
@keepyourpantsongohan I scrolled through this timeline but couldn’t find any info on when the 2nd Shinobi War began and ended.
Check out Year 52 and 55! I noted the start of the war as around the time the Sannin are 26-27. When I think it began:
Year 52-53: Second Shinobi War begins; Tsunade develops her Yin seal; Hanzo names Sannin, Jiraiya remains in Ame
Notes: The Second Shinobi war supposedly takes place 20 years after the first (Second Naruto Fanbook, Kai No Sho). Additionally, at some point during this war, Tsunade develops her Yin seal, as during Chapter 160 during some stage of the war she is seen without it, but it is very likely that she had it behind her forehead protector during her combat in Ame (Chapter 446), and it is unlikely she would develop a combat-oriented seal after Dan’s death gave her a fear of blood (Chapter 160).
And regarding its ending:
Year 55: Jiraiya returns to Konoha from Ame and becomes Minato’s teacher
Notes: Since Jiraiya identified Nagato as the first Child of Prophecy, the Ame Orphans necessarily predate the Team Jiraiya that Minato was placed on. Jiraiya taught in Ame for 3 years before returning to Konoha, which means he couldn’t have taught Minato until three years after the Second Shinobi War had begun, placing Minato at age 14. It is unclear at what point the Second Shinobi War ended, though the implication made in the Second Naruto Fanbook is that conflict flowed from the Second Shinobi War to the Third Shinobi War without pause.
So a better question might be, “When did the Second Shinobi War transition into the Third Shinobi War?”
It has to be before Sasori kills the Third Kazekage, as his actions in Suna take place during the Third Shinobi War. But that’s a whole seven years later so that’s quite a gap.
My guess would be that transition happens the year after Jiraiya returns to Konoha (Year 56). It makes sense, given how quickly Minato made a name for himself, and given how Kakashi, aged 5 year old, was allowed to graduate, and Gai the year after, etc. All of Kakashi’s cohort are considered wartime graduations—but graduations of the Third Shinobi War, rather than the Second. So the Second War likely lasted 4 years, but immediately devolved into the Third Shinobi War, which lasted an additional 8 years.
(That they at some point believed the conflicts of the Second Shinobi War to have been replaced by those of the Third Shinobi War is interesting—so I might even suggest that that transition year, Year 56, would be a very interesting time to place the destruction of Uzushio.)
