The Cluniac Reformers were a group of monastic monks of the tenth century in France. The Church in Europe was under great stress at the time due to wars and invasions by Vikings, Magyars, and Muslims. Church officials were under fiefdom to the various kings and were expected to go to war for them. The Cluny monks refused to answer to any authority but Rome. This forced reform on the Church and Kings no longer had power over Church officials. The reforms took time -- nearly two hundred years -- but it was a success.
