Louis VI

(born 1081—died Aug. 1, 1137) King of France (1108–37). He was effective ruler of France well before the death of his father, Philip I, in 1108, and he spent much time in subduing the unruly French barons. He fought Henry I of England (1104–13, 1116–20) and prevented a threatened invasion by Emperor Henry V (1124). He died a month after arranging his son's marriage to Eleanor of Aquitaine, whereupon his son succeeded him as Louis VII.
