Pan-Indianism is an intertribal movement of native resistance to white domination and assimilation, is characterized primarily by political and religious expression and solidarity.
Solidarity amongst all native american peoples, from canada, alaska, hawaii, north & south america, and the carribean.
I've got to agree (gasp!) with Samuel's remark. The word pan-indianism seems to bring a knee jerk reaction in many U.S native folks, i think because it has been used and abused.
