Louis VI (c.1081 – 1 August 1137), called the Fat (French: le Gros) or the Fighter (French: le Batailleur), was King of France from 1108 to 1137.
Chronicles called him "roi de Saint-Denis".
Louis was the first member of the house of Capet to make a lasting contribution to centralizing the institutions of royal power.
He spent almost all of his twenty-nine-year reign fighting either the "robber barons" who plagued Paris or the Norman kings of England for their continental possession of Normandy.
Nonetheless, Louis VI managed to reinforce his power considerably and became one of the first strong kings of France since the death of Charlemagne in 814.
Louis was a warrior-king, but by his forties his weight had become so great that it was increasingly difficult for him to lead in the field.
A biography – The Deeds of Louis the Fat, prepared by his loyal advisor Abbot Suger of Saint Denis – offers a fully developed portrait of his character, in contrast to what little historians know about most of his predecessors.
