The Kingdom of France and its aristocracy were prominent players in the Crusades in general. Following the Fourth Crusade, a period known as the "Frankokratia" existed where French Latin Catholics took over parts of the Byzantine Empire. A Crusade also took place on French territory in the County of Toulouse (contemporary Languedoc) with the Albigensian Crusade in the 13th century, called by Pope Innocent III. This played out on local level with fighting between the Catholic White Brotherhood and the Cathar Black Brotherhood. The Cathars lost and were subsequently exterminated. In 1312, the French monarch Philip IV of France was involved in the suppression of the Knights Templar by Pope Clement V; Philip was in deep financial dept to the Templars.
