n.
known as Louis the Younger
born 0441; 1120
died Sept. 18, 1180, Paris
King of France (113780).
One of the Capetian kings, he married Eleanor of Aquitaine in 1137, thus temporarily extending his kingdom to the Pyrenees. Doubtful of her fidelity, he had the marriage annulled in 1152 and, after the death of his second wife, married Alix of Champagne, who bore him his son and heir, Philip II Augustus. Eleanor married the future Henry II of England, who took control of Aquitaine and carried on a long rivalry with Louis (115274) marked by recurrent warfare and constant intrigue. Louis was joined by Conrad III in leading the Second Crusade (114749), which failed in all its objectives.
