PROBLEM: Passage: Within the cemetery, there are special sections allocated to graves of the participants of Polish national uprisings such as the November Uprising, the January Uprising and the Kraków Uprising. First World War casualties are buried there, including ethnically Polish soldiers conscripted into all three imperial armies: Austrian, Russian and Prussian – most of whom died in local hospitals. There are members of Polish Legions; the participants of the Charge at Rokitna; the workers killed during strikes of 1936; Second World War casualties including soldiers of the Polish September campaign of 1939. All Allied pilots shot down over Poland are buried here, including those originally buried in Warsaw, along with hundreds of Commonwealth of Nations casualties and prisoners of war who died during the German occupation; the latter brought together by the BAOR into a Commonwealth plot containing a Cross of Sacrifice. Polish partisans, the victims of Nazi crimes; and Soviet soldiers who died during their anti-German attack on Kraków in 1945, are buried here.

SOLUTION: did the Polish national uprisings cause more casualties to  to be buried at the cemetery than the First World War?

PROBLEM: Passage: When Isabella first became queen, she was only three years old. The queen mother, Maria Christina of the Two Sicilies, served as regent. The first and foremost political division of the Isabeline era was between Carlists and Cristinos (or Isabelinos), the former being supporters of Infante Carlos, Count of Molina, a rival claimant to the throne and the latter being supporters of Maria Christina and Isabella. The former supported absolute monarchism and the traditionalism of the Antiguo Régimen ("Old Regime"); they were uniformly close to the Roman Catholic Church, and generally clericalist. The latter were generally supporters of constitutional monarchy (although some, including Maria Christina herself, were more inclined toward enlightened absolutism); they were liberals of one stripe or another, ranging from liberal conservatives and those whose liberalism was strictly economic to social liberals. In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrender—notably the Convention of Vergara—left an opportunity for relatively moderate Carlists to continue to play a role in the country's politics, and many did so over the ensuing decades.

PROBLEM: Passage: The garden already existed at least in the early 18th century. During the Austrian occupation of northern Serbia 1717-39, several hospitals were established in Belgrade, including the Great military hospital. Based on the Austrian plans, the hospital was set outside of the Belgrade Fortress ("Danubian" or "German Belgrade"), in the Serbian part of the city. As shown on the map of Belgrade by Nicolas François de Spar, the Tsarigrad Road began at the Württemberg Gate (Stambol Gate), at the modern Republic Square, and headed towards "Marko's cemetery" in Tašmajdan. The hospital was situated on the road's right side, where the modern Stari Dvor is located. Behind the hospital there was a large garden, predecessor of the modern park, and further behind it, across the road was the military cemetery. Later "Marko's market" developed on the spot and today it is the area surrounding the House of the National Assembly of Serbia. After Austria lost the Austro-Turkish War of 1737–1739, the northern Serbia, including Belgrade, was returned to the Turks. One of the provisions of the 1739 Treaty of Belgrade stated that Austria had to demolish all the fortifications and military and civilian buildings it has constructed during the occupation. Many Baroque buildings were demolished. However, Austria didn't demolish the buildings outside of the fortress walls, including the Great military hospital, which, albeit as a ruin, survived until the next Austrian occupation in 1788.
 Link Information: The Treaty of Belgrade, known as the Belgrade peace was the peace treaty signed on September 18, 1739 in Belgrade, Habsburg Kingdom of Serbia (today Serbia), by the Ottoman Empire on one side and the Habsburg Monarchy on the other Answer: 2
