My reading of wiki does not match your "collectivist, shared-ownership, woman-led society" claim.

I read that they had a matrilineal kinship system that treated women as equal, not women led.

As for the collectivist, shared-ownership: Then they destroyed other Iroquoian-language tribes, including the Erie, to the west, in 1654, over competition for the fur trade.

No other Indigenous nation or confederacy had ever reached so far, conducted such an ambitious foreign policy, or commanded such fear and respect. The Five Nations blended diplomacy, intimidation, and violence as the circumstances dictated, creating a measured instability that only they could navigate. Their guiding principle was to avoid becoming attached to any single colony, which would restrict their options and risk exposure to external manipulation."
