I'm not sure if you are referring to the Great Schism...which was between Eastern (Greek Orthodox) and Western (RCC) in 1054 ( in which case Urban II would be after that date or the Avignon Papcy which was in the 14th century and pre-dates Urban by 200 years.
The Great Schism was just a pissing contest between the pope and the patriarch to see who had the bigger dick.
