Question: In what year was the city conquered where the painter of Annunciation of Cortona died?

full_context: Document 1: Ferraù Fenzoni: Ferraù Fenzoni was born in (Faenza) and arrived in Rome as a young man in the early 1580s. He was apprenticed in Rome during the papacy of Gregory XIII and worked on numerous fresco cycles under pope Sixtus V, such as the Loggia della Benedizioni in the Lateran Palace, the frescoes on the walls and vaults of the Scala Santa of the adjacent Basilica of San Giovanni in Laterano, and the decoration in the Sistine library.
Document 2: Modern history: Italian unification was the political and social movement that annexed different states of the Italian peninsula into the single state of Italy in the 19th century. There is a lack of consensus on the exact dates for the beginning and the end of this period, but many scholars agree that the process began with the end of Napoleonic rule and the Congress of Vienna in 1815, and approximately ended with the Franco-Prussian War in 1871, though the last città irredente did not join the Kingdom of Italy until after World War I.
Document 3: Southern Europe: The period between 1815 and 1871 saw a large number of revolutionary attempts and independence wars. Balkan nations began to regain independence from the Ottoman Empire. Italy unified into a nation state. The capture of Rome in 1870 ended the Papal temporal power. Rivalry in a scramble for empires spread in what is known as The Age of Empire.
Document 4: Fra Angelico: 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. 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. The story seems possible and even likely. 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. Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523. In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral. Among his other pupils were Zanobi Strozzi.
Document 5: The Annunciation, with Saint Emidius: The Annunciation, with Saint Emidius is an altarpiece by Italian artist Carlo Crivelli showing an artistic adaptation of the Annunciation. The altarpiece was painted for the Church of SS. Annunziata in the Italian town of Ascoli Piceno, in the region of Marche, to celebrate the self-government granted to the town in 1482 by Pope Sixtus IV. The painting was removed to the Pinacoteca di Brera in Milan in 1811, but passed to Auguste-Louis de Sivry in 1820, and had reached England by the mid-19th century. It has been housed in the National Gallery in London since it was donated by Henry Labouchere, 1st Baron Taunton in 1864.
Document 6: Cortona Triptych: The Cortona Triptych is a Catholic Church depiction of the Madonna and Child with saints, painted by Fra Angelico. It is now kept at the Diocesan Museum in Cortona, Italy. The painting dates from 1436-1437.
Document 7: Annunciation (van Eyck, Washington): The Annunciation is an oil painting by the Early Netherlandish master Jan van Eyck, from around 1434–1436. The panel is housed in the National Gallery of Art, in Washington D.C. It was originally on panel but has been transferred to canvas. It is thought that it was the left (inner) wing of a triptych; there has been no sighting of the other wings since before 1817. The annunciation is a highly complex work, whose iconography is still debated by art historians.
Document 8: The Entombment (Michelangelo): According to documents discovered in 1981, Michelangelo had been commissioned to paint a panel for the church of Sant'Agostino in Rome, but in the end gave back the sum received. It is probable that this work was the "Entombment", which remained unfinished upon Michelangelo's return to Florence.
Document 9: Annunciation of Cortona: The Annunciation of Cortona is a panel-painting altarpiece or retable by Fra Angelico: once housed in the Church of Gesù of Cortona, it is now held at the Museo Diocesano in Cortona.
Document 10: Vocation of the Apostles: The Vocation of the Apostles is a fresco by the Italian Renaissance painter Domenico Ghirlandaio, executed in 1481–1482 and located in the Sistine Chapel, Rome. It depicts the Gospel narrative of Jesus Christ calling Peter and Andrew to become his disciples.
Document 11: Southern Europe: The Late Middle Ages represented a period of upheaval in Europe. The epidemic known as the Black Death and an associated famine caused demographic catastrophe in Europe as the population plummeted. Dynastic struggles and wars of conquest kept many of the states of Europe at war for much of the period. In the Balkans, the Ottoman Empire, a Turkish state originating in Anatolia, encroached steadily on former Byzantine lands, culminating in the Fall of Constantinople in 1453.
Document 12: Ottoman Empire: The Serbian revolution (1804–1815) marked the beginning of an era of national awakening in the Balkans during the Eastern Question. Suzerainty of Serbia as a hereditary monarchy under its own dynasty was acknowledged de jure in 1830. In 1821, the Greeks declared war on the Sultan. A rebellion that originated in Moldavia as a diversion was followed by the main revolution in the Peloponnese, which, along with the northern part of the Gulf of Corinth, became the first parts of the Ottoman Empire to achieve independence (in 1829). By the mid-19th century, the Ottoman Empire was called the "sick man" by Europeans. The suzerain states – the Principality of Serbia, Wallachia, Moldavia and Montenegro – moved towards de jure independence during the 1860s and 1870s.
Document 13: The Last Judgment (Fra Angelico, Florence): The Last Judgment (tempera on panel) is a painting by the Renaissance artist Fra Angelico. It was commissioned by the Camaldolese Order for the newly elected abbot, the humanist scholar Ambrogio Traversari. It is variously dated to c1425, 1425–30 and 1431. It was originally sited in the church of Santa Maria degli Angeli and now is in the museum of San Marco, Florence. It is not to be confused with another Fra Angelico "Last Judgement" in the Gemäldegalerie, Berlin.
Document 14: Decline and modernization of the Ottoman Empire: The Russo - Turkish War of 1877 -- 1878 had its origins in a rise in nationalism in the Balkans as well as in the Russian goal of recovering territorial losses it had suffered during the Crimean War, reestablishing itself in the Black Sea and following the political movement attempting to free Balkan nations from the Ottoman Empire. As a result of the war, the principalities of Romania, Serbia and Montenegro, each of which had de facto sovereignty for some time, formally proclaimed independence from the Ottoman Empire. After almost half a millennium of Ottoman domination (1396 -- 1878), the Bulgarian state was reestablished as the Principality of Bulgaria, covering the land between the Danube River and the Balkan Mountains (except Northern Dobrudja which was given to Romania) and the region of Sofia, which became the new state's capital. The Congress of Berlin also allowed Austria - Hungary to occupy Bosnia and Herzegovina and Great Britain to take over Cyprus, while the Russian Empire annexed Southern Bessarabia and the Kars region.
Document 15: Annunciation (Caravaggio): The Annunciation is an oil painting by the Italian master Michelangelo Merisi da Caravaggio, finished around 1608. It housed in the Musée des Beaux-Arts de Nancy.
