question: In the Morean War, the Republic of Venice besieged Sinj in October 1684 and then again March and April 1685, but both times without success. In the 1685 attempt, the Venetian armies were aided by the local militia of the Republic of Poljica, who thereby rebelled against their nominal Ottoman suzerainty that had existed since 1513. In an effort to retaliate to Poljica, in June 1685, the Ottomans attacked Zadvarje, and in July 1686 Dolac and Srijane, but were pushed back, and suffered major casualties. With the help of the local population of Poljica as well as the Morlachs, the fortress of Sinj finally fell to the Venetian army on 30 September 1686. On 1 September 1687 the siege of Herceg Novi started, and ended with a Venetian victory on 30 September. Knin was taken after a twelve-day siege on 11 September 1688. The capture of the Knin Fortress marked the end of the successful Venetian campaign to expand their territory in inland Dalmatia, and it also determined much of the final border between Dalmatia and Bosnia and Herzegovina that stands today. The Ottomans would besiege Sinj again in the Second Morean War, but would be repelled. On 26 November 1690, Venice took Vrgorac, which opened the route towards Imotski and Mostar. In 1694 they managed to take areas north of the Republic of Ragusa, namely Citluk, Gabela, Zazablje, Trebinje, Popovo, Klobuk and Metkovic. In the final peace treaty, Venice did relinquish the areas of Popovo polje as well as Klek and Sutorina, to maintain the pre-existing demarcation near Ragusa.
Answer this question: Which event happened first, the Republic of Venice besieged Sinj or Venice took Vrgorac?
answer: Republic of Venice besieged Sinj

question: The immediate background was Napoleonic France's defeat and surrender in May 1814, which brought an end to 25 years of nearly continuous war. Negotiations continued despite the outbreak of fighting triggered by Napoleon's dramatic return from exile and resumption of power in France during the Hundred Days of March to July 1815. The Congress's "final act" was signed nine days before his final defeat at Waterloo on 18 June 1815. The Congress has often been criticized for causing the subsequent suppression of the emerging national and liberal movements, and it has been seen as a reactionary movement for the benefit of traditional monarchs. However, others praise it for having created relatively long-term stability and peaceful conditions in most of Europe. In a technical sense, the "Congress of Vienna" was not properly a congress: it never met in plenary session, and most of the discussions occurred in informal, face-to-face sessions among the Great Powers of Austria, Britain, France, Russia, and sometimes Prussia, with limited or no participation by other delegates. On the other hand, the congress was the first occasion in history where, on a continental scale, national representatives came together to formulate treaties instead of relying mostly on messages among the several capitals. The Congress of Vienna settlement, despite later changes, formed the framework for European international politics until the outbreak of the First World War in 1914.
Answer this question: How many countries are mentioned to have attended the Congress of Vienna?
answer: 5

question: The final breach is often considered to have arisen after the capture and sacking of Constantinople by the Fourth Crusade in 1204; the final break with Rome occurred circa 1450. The sacking of Church of Holy Wisdom and establishment of the Latin Empire as a seeming attempt to supplant the Orthodox Byzantine Empire in 1204 is viewed with some rancour to the present day. In 2004, Pope John Paul II extended a formal apology for the sacking of Constantinople in 1204, which was importantly also strongly condemned by the Pope at the time ; the apology was formally accepted by Patriarch Bartholomew of Constantinople. Many things that were stolen during this time holy relics, riches, and many other itemswere not returned and are still held in various European cities, particularly Venice. Reunion was attempted twice, at the 1274 Second Council of Lyon and the 1439 Council of Florence. The Council of Florence briefly reestablished communion between East and West, which lasted until after the fall of Constantinople in 1453. In each case, however, the councils were rejected by the Orthodox people as a whole, and the union of Florence also became very politically difficult after Constantinople came under Ottoman rule. Some local Eastern Churches have, however, renewed union with Rome in time since . Recent decades have seen a renewal of ecumenical spirit and dialogue between the Churches.
Answer this question: How many years passed between the first and second attempts at reunion?
answer:
165
