In 1110 Fulk V le Jeune married Eremburge of Maine. When her father, Count Elias, died a few months later, Fulk V became the Count of Maine in right of his wife. But this brought him into immediate conflict with King Henry I of England who also claimed Maine. For a time Fulk was the first Angevin count to directly rule Maine. In 1113 Henry I arranged to meet with Fulk V at Alençon. There they arranged a peace agreement. To seal the agreement they made a marriage alliance. Fulk's infant daughter, Matilda, was promised in marriage to Henry's nine year old son, William Adelin. Fulk V remained the Count of Maine but he swore fealty to King Henry I as his overlord. Without his Angevin ally Fulk, King Louis VI of France was forced to make peace with King Henry I. King Louis confirmed the lordship (overlordship) of Maine to Henry I. Henry then attacked the lands of Robert de Bellême; joined by Fulk V. Bellême was defeated and Henry I returned to England. Fulk V returned to Anjou to deal with a revolt in Angers.
