The Albigensian Crusade (aka Cathars' Crusade, 1209-1229 CE), was the first crusade to specifically target heretic Christians - the Cathars of southern France. Not successful in repressing the heresy, the on-off campaigns over two decades, led by Simon IV de Montfort, did achieve their real purpose: the political annexation of the Languedoc region, eventually bringing it under the control of the French Crown. The Crusade set a precedent for attacking fellow Christians which would be repeated in Germany, Bosnia and the Baltic regions.
