During the period from Henry's accession to the birth of Eleanor's youngest son John, affairs in the kingdom were turbulent: Aquitaine, as was the norm, defied the authority of Henry as Eleanor's husband and answered only to their Duchess. Attempts were made to claim Toulouse, the rightful inheritance of Eleanor's grandmother Philippa of Toulouse, but they ended in failure. A bitter feud arose between the king and Thomas Becket, initially his Chancellor and closest adviser and later the Archbishop of Canterbury. Louis of France had remarried and been widowed; he married for the third time and finally fathered a long hoped-for son, Philip Augustus, also known as Dieudonne—God-given). "Young Henry," son of Henry and Eleanor, wed Marguerite of France, daughter of Louis from his second marriage. Little is known of Eleanor's involvement in these events. It is certain that by late 1166, Henry's notorious affair with Rosamund Clifford had become known, and Eleanor's marriage to Henry appears to have become terminally strained.
