pope (september 20 ,827 -January 11 ,844 ), was chosen to succeed Valentine in December 827, on which occasion he recognized the supremacy of the Frankish emperorLouis the Pious in the most unequivocal manner.Papal dependence on the
Holy Roman Emperor loosened through the quarrels of Louis I the Pious and his sons, the futureLothair I , Pepin andLouis the German . On the sons' rebellion against their father, Gregory supported Lothair, hoping his intervention would promote peace, but in practice this action annoyed the Frankish bishops. Gregory's response was to insist upon the primacy ofSt Peter 's successor, the papacy being superior to the Emperor.The two armies, of Louis and his sons, met at
Rotfeld , nearColmar , in the summer of 833. The sons persuaded Gregory to go to Louis' camp to negotiate, but he then found he had been duped by Lothair. Louis was deserted by his supporters and was forced to surrender unconditionally, and was deposed and humiliated. This sequence of events is known as theCampus Mendacii or "field of lies."Louis was subsequently restored, and after his death Gregory made unsuccessful attempts to mediate in the conflict that ensued between the brothers.Gregory contributed to the architectural development of Rome (he rebuilt the Basilica di San Marco) and promoted the celebration of the feast of
All Saints .He is also known for his appointment of
Ausgar forarchbishop ofHamburg andBremen , and a missionary delegate for north and east parts of Europe. He also fortified the port of Ostia against the attacks ofSaracens .References
