Geoffrey inaugurated a policy of expansion, having as its objects the extension of the boundaries of the ancient countship and the reconquest of those parts of it which had been annexed by other states; for, though western Anjou had been recovered from the dukes of Brittany since the beginning of the 10th century, in the east all the district of Saumur had already by that time fallen into the hands of the counts of Blois and Tours. Geoffrey Greytunic succeeded in making the Count of Nantes his vassal and in obtaining from the Duke of Aquitaine the concession in fief of the district of Loudun. Moreover, in the wars of King Lothaire against the Normans and against the emperor Otto II, he distinguished himself by feats of arms which the epic poets were quick to celebrate.
