Gregory XII, Pope (papal states) : All Data

Gregory XII was the Pope who ruled over the Papal States from 1406 to 1415. During his tenure, he faced the Western Schism, a major conflict within the Catholic Church that lasted from 1378 to 1417. This schism resulted in multiple claimants to the papacy, leading to a divided church and political turmoil. Gregory XII played a significant role in attempting to resolve the schism, ultimately resigning in 1415 as part of the Council of Constance's efforts to reunify the church. While he did not directly oversee any specific wars, the Western Schism itself was a period of intense conflict and power struggles within the Catholic Church.
