#|| That and the Uchiha had no footing after Madara's betrayal so it's laughable to think they could even invoke favors from anyone.

i'd love if you write an in depth clan alliance!

It is not too terribly in-depth.

Here's like the most precise way I can list it without droning on for 500000+ paragraphs:

Senju

Uzumaki - Relative clan via marriage.

Sarutobi - First Ally

Shimura - First Ally

Uchiha

Hyuuga; Kept - First Ally

Fuma; Kept - First Ally

Hagoromo; Given up

Hozuki; Given Up

Taketori; partially given up (does not exist within Konoha borders) but exist through extension of the Hyuuga clan.

Those are all the named clans that persisted from the Warring State Periods into Founders Era. I can argue that since the Uchiha never took control of the country/it is """""""""technically"""""""" democratic (hard quotations as it seems to be rather nepotism-coded despite Tobirama's literal one command for popular sovereignty— to fault of the writer), all later allied clans are under Senju allegiance. It sort of hard stops here because everything after Hashirama's incumbency is at namesake of Konoha; not to any one clan.

The later noble clans (Aburame, Akimichi) and whoever else (Hatake, Yamanaka, etc) joined under Konoha, not the Senju specifically. Even if the existing Senju members, at the time, still want to claim ownership over their allegiance due to dominant control of the land.

I've had some unnamed/made-up clans as place holders for either clan during WSP, but presumably were retired/disbanded/did not pledge to Konoha.
