Are you speaking of the Great Schism of 1054 or of the Great Western Schism of 1378? The Great Schism of 1054 led to the origination of the Western Roman Catholic (i.e., universal) Church and the opposing Eastern Orthodox Church. The Great Western Schism of 1378, on the other hand, occurred within the Western Roman Catholic Church. Basically, The French would not accept Urban as Pope and appointed Clement, based in Avignon, as the rightful Pope. The Western countries were torn about whom to obey as Pope of Christendom. Depending upon which Schism you are speaking of, the affects on the advance of Europe would be quite different. In the Schism of 1054, the greatest affect might be to cause people to hold more tightly to old forms as the rupture was essentially over the validity of forms of orthodox worship. In the Schism of 1378, the greatest affect might be to turn to new ideas since the established ones were crumbling in animosity around adherents.
