`  : I undid your version because the sentence didn't make much sense to me in English.  `` The French city of Avignon was part Western Schism between 1309-1377 , during witch it was the see of one of the persons claiming to be pope.``  From what I understand the Western Schism ocurred after the papacy moved back to Rome, so how could Avignon be ``part Western Schism between 1309-1377``?  (I'm assuming you meant ``part of the Western Schism``)  Also, there were 7 popes during the Avignon papacy, ``one of the persons`` is misleading...and was there someone else somewhere else who claimed to be pope during this time?  If you clarify your message I would be happy to help you formulate it. Regards  `
