What about this:
Portugal came into existence as an independent nation on June 24, 1128, when Afonso Henriques, Count of Portugal, defeated his mother in battle, Countess Teresa, and her lover, Fernão Peres de Trava, thereby establishing himself as sole leader. Afonso Henriques proclaimed himself king of Portugal on July 25, 1139, after the Battle of Ourique and was recognized as such in 1143 by Alfonso VII, king of León and Castile, and in 1179 by Pope Alexander III.
If it is true, not Portugalia but e.g. Navarre should be
the faction.
