In Byakhiams new duchy setup mod, Branganza represents the (arch)bishopric of Braganza
Byakhiam said:Duchy of Porto would be Porto, Braganza, Castelo Branco and Coimbra.
The problem area is the area between those four and Algarve in the south.
Finellach said:Indeed. That area is also wrong IMO. As it is now we have Tejo(Alentejo?) and Viseu(???) inbetween.
