3 In the twelfth century Our predecessors Innocent II, Lucius II, and Alexander III accepted the service of obedience offered by Alfonso Henriques, first Count of Portugal and afterward King. They promised him their protection over all the territory which he had recovered in battle from Moorish domination and declared its liberation legitimate. The acts by which this was accomplished honorably rewarded the Portuguese people for their outstanding success in safeguarding the faith they had acquired.
