Gavrilo Princip (Serbian Cyrillic: , ] ; 25 July [O.S. 13 July] 1894 28 April 1918) was a Bosnian Serb member of Young Bosnia, a Yugoslavist organization seeking an end to Austro-Hungarian rule in Bosnia and Herzegovina.
 He assassinated Archduke Franz Ferdinand of Austria and his wife, Sophie, in Sarajevo on 28 June 1914, setting off a chain of events that would lead to outbreak of the First World War.
 Princip and his accomplices were arrested and implicated the Serbian nationalist secret society known as the Black Hand, leading Austria-Hungary to issue a démarche to Serbia known as the July Ultimatum.
 This was used as pretext for Austria-Hungary's invasion of Serbia, which then led to World War I.
 Princip was a Yugoslav nationalist associated with the movement Mlada Bosna (Young Bosnia) which predominantly consisted of Serbs, but also Bosniaks and Croats.
 During his trial he stated: "I am a Yugoslav nationalist, aiming for the unification of all Yugoslavs, and I do not care what form of state, but it must be freed from Austria."
 Princip died on April 28, 1918, from tuberculosis caused by poor prison conditions that had cost him a limb earlier.
Radonja Petrović (; Kosor, Kuči, 1670– Jelica mountain, Stari Vlah, 1737), known as Vojvoda Radonja (војвода Радоња) was the "vojvoda" (duke) of the Kuči tribe.
 Radonja's father Petar was a middle child of Vojvoda Iliko Lalev and held the title until his death when it was passed to his brother priest Mirčeta.
 Radonja, thus, succeeded his uncle Mirčeta as the duke of Kuči, being the great-great-grandson of Drekale, eponymous founder of Drekalovići.
 He came to be the leader of a group of tribes in what is today eastern Montenegro (known as Brda, "the Hills") that together with Habsburg Serbian troops fought against the Ottomans, and was granted the title "Guvernadur of all the Hills" by Venetians, for whom he managed the postal traffic with the Ottomans.
 Prince-bishop Vasilije in his "History of Montenegro" mentions him as one of the Montenegrin commanders who rose to arms under the influence of Prince-bishop Danilo in 1711.
 In the talks with Austrian representatives in the village of Tešići near Niš, held on 24 July 1737, Radonja and Patriarch Šakabenta promised field marshal Seckendorff that they would mobilise the Highlanders.
 The Kuči would ready 500 armed men, vojvoda Vuksan Vojvodić of Vasojevići 200, vojvoda Toško of Piperi 200, etc.
 The Serbian Patriarch and Radonja called on Metropolitan Sava to join the war against the Ottomans, but he was under the influence of the Republic of Venice, and stayed inactive during the war.
 Radonja requested from the Austrian "feltmarschal" that in case the rebels won, they would continue in his service.
 When talks were underway, an uprising broke out in Montenegro.
 Radonja's rebels and Serbian troops, and an auxiliary force of Staniša Marković-Mlatišuma, attacked the local Muslims.
 According to Serbia's plan, they were to take over Novi Pazar, Rožaje, Bijelo Polje and Peć.
 A Serbian detachment attacked Bihor, and penetrated to Godijevo, where they set up a headquarters in the house of Mustafa Sijarić.
 Radonja heard that the Ottomans would in their future actions first attack Župljani, which had already crossed to the Venetian side.
 At the same time, Radonja informed Cattaro intendant Jerolim Buća that Derviš-paša Čengić was ordered to turn with his army from the Sanjak of Herzegovina towards Knin, which they were to attack; and that vezir-Mustafa-paša with the armies of other sanjaks and 4,000 Tatars, as was planned, turn in the direction of Zadar.
 That information was likely exaggerated.
 Radonja died on the Jelica mountain in 1737 and was buried there.
 In 1766, his son Grigorije, who became the arhimandrite of Niš, transported his remains and reburied them in the village of Bošnjace near Leskovac.
 In 2014 he was exhumated yet again and buried in his birth village of Kosor.
 After his death, his uncle Mirčeta's grandson Martin Popović was elected as Vojvoda.
 Radonja's siblings and their descendants continued to bear the surname of Petrović, whilst his offspring adopted the surname Radonjić.
Peter Handke (] ; born 6 December 1942) is an Austrian novelist, playwright and translator.
 His writings about the Yugoslav Wars and subsequent NATO bombing of Yugoslavia with criticism of the Western position and his speech at the funeral of Slobodan Milošević have caused controversy, and he has been widely described as an apologist for far-right Serbian nationalism.
 He has been awarded the Georg Büchner Prize, the Franz Kafka Prize and the International Ibsen Award; the latter award was extremely controversial and Handke was met by protesters in Oslo and widely described by critics in Norwegian media as a fascist with ties to war criminals.
 In 2006 his nomination for the Heinrich Heine Prize caused a scandal, and the prize was withdrawn due to his political views.
The Left Coalition was a coalition of left-wing political parties in Serbia for the 1997 Serbian general election.
 The coalition was made up of the Socialist Party of Serbia (SPS), Yugoslav Left (JUL) and New Democracy (ND).
 It was led by Slobodan Milošević the leader of SPS, but also main actors were Mirjana Marković the leader of Yugoslav Left and Dušan Mihajlović the leader of New Democracy.
 The coalition received 1,415,456 votes or 34.26% of the popular vote.
 Following the election, it formed a coalition government with the Serbian Radical Party (SRS).
The Zagreb Soloists (Croatian: "Zagrebački solisti" ) is a chamber orchestra founded in Zagreb, Croatia, in 1953 through the auspices of Zagreb Radiotelevision, under the artistic leadership of the Italian cellist and conductor, Antonio Janigro.
 After Janigro left the ensemble in 1968, the group was led first by their concertmaster, Dragutin Hrdjok, and then by their longtime artistic director and concertmaster, Tonko Ninić.
 In 1997, Anđelko Krpan became concertmaster, and in 2002, Karlo Slobodan Fio, took over as artistic director of the ensemble.
 Since 2006, the concertmaster and artistic leader has been Borivoj Martinic-Jercic.
The "Anti-bureaucratic revolution" was a campaign of street protests ran between 1986 and 1989 in former Yugoslavia by supporters of Serbian leader Slobodan Milošević.
 The protests, termed "Rallies of Truth" (), overthrew the governments of the Serbian autonomous provinces of Vojvodina and Kosovo, as well as the government of the Socialist Republic of Montenegro, and replaced them with allies of Milošević, thereby creating a dominant voting bloc within the Yugoslav presidency council.
Slobodan Princip (; 25 May 1914–May 1942), nicknamed Seljo (Сељо), was a Yugoslav Partisan fighter and the district staff chief of Partisan Sarajevo Oblast during World War II.
 He was posthumously awarded the Hero of Yugoslavia.
 He was the nephew of Gavrilo Princip.
The League of Communists of Serbia (, Савез комуниста Србије, SKS), founded as the Communist Party of Serbia (, Комунистичка партија Србије, KPS) in 1945, was the Serbian branch of the League of Communists of Yugoslavia, the sole legal party of Yugoslavia from 1945 to 1990.
 It changed its name from KPS to SKS in 1952.
 Under a new constitution ratified in 1974, greater power was devolved to the various republic level branches.
 In the late 1980s, the party was taken over by a faction endorsing Slobodan Milošević to become leader of the party.
 Milošević appeased nationalists in Serbia by promising to reduce the level of autonomy within the autonomous provinces of Kosovo and Vojvodina.
 This policy increased ethnic tensions with the other republics and nationalities.
 During the early 1990s, the growing ethnic tensions between the republics of Yugoslavia led to the breakup of the federal party.
Yugoslavism (Југославизам, Slovene: "Jugoslavizem" ) or Yugoslavdom (Југословенство, Slovene: "Jugoslovanstvo" ) refers to the nationalism or patriotism associated with South Slavs and Yugoslavia.
 Yugoslavism has historically advocated the union of all South Slav populated territories now composing Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, Serbia (and the disputed region of Kosovo, which now has a Slavic minority), Slovenia, and Macedonia.
 It became a potent political force during World War I with the assassination of Austrian Archduke Franz Ferdinand by the Yugoslavist militant Gavrilo Princip and the subsequent invasion of Serbia by Austria-Hungary.
 During the war the Yugoslav Committee composed of South Slav emigres from Austria-Hungary (including twelve Croats, three Serbs, and one Slovene), supported Serbia and vouched for the creation of a Yugoslav state.
 However the assassination of Franz Ferdinand triggered resentment amongst those Austro-Hungarian Croats and Slovenes who had favoured being within Austria-Hungary.
The July Crisis was a diplomatic crisis among the major powers of Europe in the summer of 1914 that led to World War I.
 Immediately after Gavrilo Princip, a Slavic nationalist, assassinated Archduke Franz Ferdinand, heir presumptive to the Austro-Hungarian throne, in Sarajevo, a series of diplomatic manoeuvres led to an ultimatum from Austria-Hungary to the Kingdom of Serbia, and eventually to war.
