The Constable of France (French: Connétable de France, from Latin comes stabuli for 'count of the stables') was lieutenant to the King of France, the first of the original five Great Officers of the Crown (along with seneschal, chamberlain, butler, and chancellor) and the commander-in-chief of the Royal Army. He was, at least on paper, the highest-ranking member of the French nobility.
The Connétable de France was also responsible for military justice and served to regulate the Chivalry. His jurisdiction was called the Constabulary (connestablie; or in modern French orthography which sticks closer to the correct pronunciation: connétablie).
