In 751 the Lombards had conquered the imperial territory at Ravenna, the seat of Byzantine government in Italy, and were demanding tribute from the pope and threatening to take Rome. Following Pepin’s coronation, the pope secured his promise of armed intervention in Italy and his pledge to give the papacy the territory of Ravenna, once it was conquered. In 756 a Frankish army forced the Lombard king to surrender his conquests, and Pepin officially conferred the Ravenna territory upon the pope. Known as the "Donation of Pepin," the gift made the pope a temporal ruler over the Papal States, a strip of territory that extended diagonally across Italy from coast to coast.
