Question: What year was the conquest of the city where Gioffre Borgia's father died?

full_context: Document 1: 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 2: 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 3: Palermo: After the Treaty of Utrecht (1713), Sicily was handed over to the Savoia, but by 1734 it was again a Bourbon possession. Charles III chose Palermo for his coronation as King of Sicily. Charles had new houses built for the growing population, while trade and industry grew as well. However, by now Palermo was now just another provincial city as the Royal Court resided in Naples. Charles' son Ferdinand, though disliked by the population, took refuge in Palermo after the French Revolution in 1798. His son Alberto died on the way to Palermo and is buried in the city. When the Kingdom of the Two Sicilies was founded, the original capital city was Palermo (1816) but a year later moved to Naples.
Document 4: 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 5: Gioffre Borgia: Gioffre Borgia (born 1481 or 1482; died 1516 or 1517), also known as Goffredo (Italian), or Jofré Borja (Catalan), was the youngest son of Pope Alexander VI and Vannozza dei Cattanei, and a member of the House of Borgia. He was the youngest brother of Cesare, Giovanni, and Lucrezia Borgia.
Document 6: Juan Castellar y de Borja: Juan Castellar y de Borja was born in Valencia in late 1441, the son of Galcerán de Castellar, "señor" de Picassent, and his wife Bernardona Borja. The Castellar family was allied with the Borja family. He was a cousin of Cardinal Juan de Borja Lanzol de Romaní, "el mayor".
Document 7: Napoleon: Unhappy with this change of policy by the Portuguese government, Napoleon sent an army to invade Portugal. On 17 October 1807, 24,000 French troops under General Junot crossed the Pyrenees with Spanish cooperation and headed towards Portugal to enforce Napoleon's orders. This attack was the first step in what would eventually become the Peninsular War, a six-year struggle that significantly sapped French strength. Throughout the winter of 1808, French agents became increasingly involved in Spanish internal affairs, attempting to incite discord between members of the Spanish royal family. On 16 February 1808, secret French machinations finally materialized when Napoleon announced that he would intervene to mediate between the rival political factions in the country. Marshal Murat led 120,000 troops into Spain and the French arrived in Madrid on 24 March, where wild riots against the occupation erupted just a few weeks later. Napoleon appointed his brother, Joseph Bonaparte, as the new King of Spain in the summer of 1808. The appointment enraged a heavily religious and conservative Spanish population. Resistance to French aggression soon spread throughout the country. The shocking French defeat at the Battle of Bailén in July gave hope to Napoleon's enemies and partly persuaded the French emperor to intervene in person.
Document 8: Sancha of Aragon: Sancha of Aragon (1478 in Gaeta – 1506 in Naples), or Sancia of Aragon, was an illegitimate daughter of King Alfonso II of Naples and his mistress Trogia Gazzela. In 1494, she was married to Gioffre Borgia, youngest son of Pope Alexander VI. Upon her marriage, she and her husband were created Prince and Princess of Squillace, a province in the south of Italy. For the majority of their marriage, Sancha and her husband lived in the Vatican with the rest of his family. There Sancha became friends with her sister-in-law Lucrezia, and allegedly had affairs with both of her husband's older brothers: Juan Borgia, 2nd Duke of Gandia, also known as Giovanni Borgia, and Cesare Borgia. Her affair with Juan is sometimes said to be the reason for Cesare's alleged murder of Juan in 1497.
Document 9: Franceschetto Cybo: Despite his exceeding passion for card playing, he received from his father important positions in the Papal States: governor of Rome (1488), the fiefs of Cerveteri and Anguillara (1490) and the title of Count of the Lateran Palace. In 1490 he attempted to steal the Papal treasure.
Document 10: Lucrezia Borgia: Lucrezia Borgia (; ; 18 April 1480 – 24 June 1519) was a Spanish-Italian noblewoman of the House of Borgia who was the daughter of Pope Alexander VI and Vannozza dei Cattanei. She reigned as the Governor of Spoleto, a position usually held by cardinals, in her own right.
Document 11: 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 12: Late Middle Ages: Avignon was the seat of the papacy from 1309 to 1376. With the return of the Pope to Rome in 1378, the Papal State developed into a major secular power, culminating in the morally corrupt papacy of Alexander VI. Florence grew to prominence amongst the Italian city-states through financial business, and the dominant Medici family became important promoters of the Renaissance through their patronage of the arts. Other city states in northern Italy also expanded their territories and consolidated their power, primarily Milan and Venice. The War of the Sicilian Vespers had by the early 14th century divided southern Italy into an Aragon Kingdom of Sicily and an Anjou Kingdom of Naples. In 1442, the two kingdoms were effectively united under Aragonese control.
Document 13: Anna d'Este: Anna d'Este was born on 16 November 1531, the eldest daughter of the Duke of Ferrara Ercole II (son of Lucrezia Borgia and grandson of Pope Alexander VI) and his wife, Renée of France (daughter of King Louis XII of France). She grew up in Ferrara, where she received an excellent education. The future writer and scholar Olympia Fulvia Morata was chosen as one of her companions at court.
Document 14: Pope Alexander VI: On 25 January 1494, Ferdinand I died and was succeeded by his son Alfonso II (1494–1495). Charles VIII of France now advanced formal claims on the Kingdom of Naples. Alexander authorised him to pass through Rome, ostensibly on a crusade against the Ottoman Empire, without mentioning Naples. But when the French invasion became a reality Pope Alexander VI became alarmed, recognised Alfonso II as king of Naples, and concluded an alliance with him in exchange for various fiefs for his sons (July 1494). A military response to the French threat was set in motion: a Neapolitan army was to advance through the Romagna and attack Milan, while the fleet was to seize Genoa. Both expeditions were badly conducted and failed, and on 8 September Charles VIII crossed the Alps and joined Ludovico il Moro at Milan. The Papal States were in turmoil, and the powerful Colonna faction seized Ostia in the name of France. Charles VIII rapidly advanced southward, and after a short stay in Florence, set out for Rome (November 1494).
Document 15: 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.
