| Additional information |
Afonso III came to the Portuguese throne by deposing his own brother Sancho II — a move sanctioned by Pope Innocent IV in 1245 through the papal bull Grandi non immerito, which declared Sancho incompetent to rule. The coinage that followed reflects a reign spent consolidating royal authority against both the nobility and the Church, culminating in a direct confrontation with the Portuguese bishops that resulted in Afonso's excommunication in 1268. He died still under that sentence.
