A 'Native American' Wank?

[sansahansan]

Has there been, in AH history, a 'native american' wank, preferably led by the Iroquois?

If not, I'm thinking a potential TL...
A stronger earlier nordic entrance around 900ad that still fails, but brings 1) advanced social reforms, 2) ironworking and 3) advanced agriculture to the North East natives.

With their climate, iron working, advanced agriculture, and possibly advanced childcare/midwifery, a population explosion occurs, triggering an agricultural revolution across North America, stopping only on the great plains, but technology is traded across nomadic hunters of bison into the western mountains by 1400, resulting in early medieval style cities in the Mississippi and Missouri river valleys by 1500... and ocean sailing experimentation by the time Europeans fully arrive in the Caribbean.

Nasty shock to the early European colonists, isn't it?

Too much a wank, or possible?
