Task: Question Generation
Input (English): The French crown's increasing dominance over the Papacy culminated in the transference of the Holy See to Avignon in 1309. When the Pope returned to Rome in 1377, this led to the election of different popes in Avignon and Rome, resulting in the Papal Schism (1378–1417). The Schism divided Europe along political lines; while France, her ally Scotland and the Spanish kingdoms supported the Avignon Papacy, France's enemy England stood behind the Pope in Rome, together with Portugal, Scandinavia and most of the German princes.
Output (English): Where was the Holy See transferred to in 1309?
