Hi ! So glad I find your master worldbuilding mind!

Quick question, how do you think we went from a clan-based village to actual Konoha where several clans (Senju, Sarutobi?, Uchiha, Danzo clan? , Hatake if it's a clan) have disapear? Did the village care ou try to protect them? Did other clans are treathen by the possibilities to be let down?

Because you said that Tobirama trust Uchiha with police force but Sarutobi was obsessed by clan balance and all. I know Sarutobi is old, so a lot could have happening.

Any thought?

Hi! Okay so this ask is actually based on a slightly flawed premise (not your fault it's Kishi's worldbuilding again) in that we do not actually see a lot of "wiped out" clans. What we see is Kishi not bothering to flesh out the clans he has because what is attention span. For example; the Sarutobi are not wiped out! There is exactly one shot of the Sarutobi clan in the 4th war arc that is in both the manga and the anime (in the anime the shot is actually narrower so you can't see as many as in the manga shot) where a bunch of their jounin and chuunin members (like easily double digits, I forget the exact number but I wanna say around 20ish? With more implied to be off screen) breathe fire at the juubi in sync. And it is confirmed they are all Sarutobi. There's like one guy who's essentially like: COME ON GUYS LET'S SHOW THEM THE SARUTOBI CLAN KICKS ASS.

So the Sarutobi clan is actually a decent enough/healthy enough size, we just literally never hear or see it until that one single shot. So it's reasonable to assume most clans are healthy and protected by Konoha. This is kind of implicitly supported by the narrative too, because things like the Uchiha and Hatake and Senju being nearly extinct are things that people comment on and find noteworthy, which means it's *not* the norm.

As for how the three clans we know of being wiped out *got* wiped out, I think that is less the fault of Konoha itself (tho Hiruzen is directly at fault for allowing the Uchiha massacre thanks) and more a side effect of that transition from clan based society to village based society. Namely the multiple shinobi wars. As I mentioned in my economics rant, the shinobi wars were something entirely out of the league of clan wars back in the day in terms of scale and destruction, so clans that got hammered likely were ones either already on the small size (like the Hatake probably were) or ones that would have been intentionally targeted by the enemy out of fear (Senju and Uchiha). The sheer scale of the conflict and clashing powers would have decimated targeted clans, and the villages would have been unprepared for that kind of issue until it was too late. After that, the surviving members could have easily died out without having kids post war, or if they were female members in the case of, say, the Senju, they didn't die out but the *name* died out, because it's still traditional in Naruto world cultures for the woman to join the family of the man and not the other way around (with the exception of the Uchiha and other regularly manifesting kekkei genkai clans I imagine).

We don't see anything about the Shimura clan either way beyond Danzo, which is again a flaw in the kishi worldbuilding, so we don't know if he actually has a clan still running around, or if they were just a small clan that got hammered in the multiple shinobi wars. On that note you can apply this same worldbuilding problem to almost every other village in the show. Kumo, Iwa, and Suna all have characters who are implied to be from a clan or have kekkei genkai that appear to be hereditary but no clan is mentioned. So we just do not know if there IS a clan of say- people with hand mouths like Deidara, or if they are one-off manifestations of a kekkei genkai, or if they are survivors of other villages' clans that got hammered casualty-wise by the wars like the Senju and Hatake presumably were.

Logistically speaking it would be beneficial for the villages as a whole to do everything they could to keep their clans alive, since their clans are where their powerhouses tend to come from while civilian-born shinobi fill out the ranks with more mid-level shinobi. There would probably be incentives and benefits offered by the village for clan shinobi to marry and have kids that bear the clan name, etc etc. And clans that are still a healthy size work hard to keep it that way.

I hope that answered your question?
