Burghers and monarchs were united in their frustration at the Catholic Church not paying any taxes to secular states while itself collecting taxes from subjects and sending the revenues disproportionately to Italy. Martin Luther denounced the Pope for involvement in politics. Luther's doctrine of the two kingdoms justified the confiscation of church property and the crushing of the Great Peasant Revolt of 1525 by the German nobles. This explains the attraction of some territorial princes to Lutheranism. Along with confiscated Catholic church property, ecclesiastical (Catholic) dominions became the personal property of the holder of the formerly religious office, for the right to rule was attached to this office.
