A two-state solution for the Time Frame (Marco Temporal) in Brazil

I would also make one for: Tawantinsuyu National Authority; for Aymara National Authority; Guarani National Authority; Anahuac National Authority; Maya National Authority; Turtle Island National Authority; Mapuche National Authority; Aboriginal National Authority; and so on. But that's just too much effort and I don't think it is needed for now lol.
