Cool and Interesting Alternate Migrations

Sumerians to Caspian region

Albanians to Greece and Thrace

Vikings to New England

Magyars to Italy

Or slavs to Italy :cool:

Finns/Estonians to central Russia

Allemanni to Provence/ Cote d`Azur region
 
Polynesians migrate to parts of the New World, establish permanent trade with the natives. Natives get chickens, maybe some other livestock, and shipbuilding technology; Polynesians get better crops ...

This did happen:) Polynesians got Kumara

The Liangzhu and Hemudu cultures were Proto-Austronesian and I would love to have seen an expansion north through China rather than south to Taiwan and SEA.

Of course we could also have the Cham move across India

The Tocharian invasion of China would be really interesting

and of course Moorish Europe
