Question: In what year did the Pope return from Avignon to the city where the creator of the Perugia Altarpiece died?

<P0-S0> the avignon papacy was the period from 1309 to 1376 during which seven successive popes resided in avignon (then in the kingdom of arles, part of the holy roman empire, now in france) rather than in rome. <P0-S1> the situation arose from the conflict between the papacy and the french crown, culminating in the death of pope boniface viii after his arrest and maltreatment by philip iv of france. <P0-S2> following the further death of pope benedict xi, philip forced a deadlocked conclave to elect the french clement v as pope in 1305. clement refused to move to rome, and in 1309 he moved his court to the papal enclave at avignon, where it remained for the next 67 years. <P0-S3> this absence from rome is sometimes referred to as the "babylonian captivity of the papacy". <SEP> <P1-S0> in the next august ladislaus died, and braccio freed bologna after receiving a payment of 180,000 gold ducats. <P1-S1> he thus invaded and conquered most of umbria, his goal being again the beloved perugia. <P1-S2> the city gave itself to carlo malatesta. <P1-S3> at the battle of sant'egidio (12 july 1416, later portrayed in a famous fresco by paolo uccello), the "bracceschi" were victorious, and perugia was finally forced to open its gates to braccio da montone. <P1-S4> other umbrian cities, such as todi, narni, orvieto and terni named him as lord: at this point, braccio da montone was ready to form a state for himself in central italy. <P1-S5> he asked the newly elected pope martin v to name him papal vicar for umbria, but martin replied by sending against him two armies under guidantonio da montefeltro, from the north, and under sforza, from the south, but montone defeated them at spoleto. <P1-S6> on 14 march 1419 he met the pope in florence, obtaining the long-awaited title (including the lordships of perugia, todi, assisi, spello, jesi and others) in exchange for ousting antongaleazzo bentivoglio from bologna. <P1-S7> after conquering the latter, he could finally retreat in perugia to enjoy ruling the city which had ousted him and his family many years ago. <SEP> <P2-S0> The Perugia Altarpiece (Italian: "Pala di Perugia") is a painting by the Italian early Renaissance painter Fra Angelico, housed in the Galleria Nazionale dell'Umbria of Perugia, Italy. <SEP> <P3-S0> Vasari claims that at this time Fra Angelico was offered the Archbishopric of Florence by Pope Nicholas V, and that he refused it, recommending another friar for the position. <P3-S1> The story seems possible and even likely. <P3-S2> However, if Vasari's date is correct, then the pope must have been Eugene IV and not Nicholas, who was elected Pope only on 6 March 1447. <P3-S3> Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523. <P3-S4> In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral. <P3-S5> Among his other pupils were Zanobi Strozzi. <P3-S6> In 1445 Pope Eugene IV summoned him to Rome to paint the frescoes of the Chapel of the Holy Sacrament at St Peter's, later demolished by Pope Paul III. <SEP> <P4-S0> The French crown's increasing dominance over the Papacy culminated in the transference of the Holy See to Avignon in 1309. <P4-S1> 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). <P4-S2> 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.
