I do believe there are eras before Warring States because I suppose nations had to be established and have a lot of power to start hiring clans like that.

However, not really sure if the Uchiha and Senju were always the most powerful clans from the start. Maybe they could of been still developing, I'm not sure. Or maybe not participating or maybe other clans just happened to be stronger, and then these clans surpassed them. Is it likely they were on top the whole period? (Doesn't want to assert an answer).
