By the late 11th century, León possessed the region as a stepping-stone to Portugal. The settlement of the village of Miranda developed through the initiative of King Denis, in an area that lay between the lateral slopes of the Douro and Fresno Rivers. It was in Miranda that the Treaty of Alcanices was signed between Denis and Ferdinand IV of Castile, setting the border between the Kingdom of Portugal and the Crown of Castile.
