<P> This changed in May 1903, when Serbian military officers led by Dragutin Dimitrijević stormed the Serbian Royal Palace . After a fierce battle in the dark, the attackers captured General Laza Petrović, head of the Palace Guard, and forced him to reveal the hiding place of King Alexander I Obrenović and his wife Queen Draga . The King and Queen opened the door from their hiding place . The King was shot thirty times; the Queen eighteen . MacKenzie writes that "the royal corpses were then stripped and brutally sabred ." The attackers threw the corpses of King Alexander and Queen Draga out of a palace window, ending any threat that loyalists would mount a counterattack ." General Petrović was then killed too (Vojislav Tankosić organized the murders of Queen Draga's brothers; Dimitrijević and Tankosić in 1913--1914 figure prominently in the plot to assassinate Franz Ferdinand). The conspirators installed Peter I of the House of Karađorđević as the new king . </P> <P> The new dynasty was more nationalist, friendlier to Russia and less friendly to Austria - Hungary . Over the next decade, disputes between Serbia and its neighbors erupted, as Serbia moved to build its power and gradually reclaim its 14th century empire . These conflicts included a customs dispute with Austria - Hungary beginning in 1906 (commonly referred to as the "Pig War"); the Bosnian crisis of 1908--1909, in which Serbia assumed an attitude of protest over Austria - Hungary's annexation of Bosnia - Herzegovina (ending in Serbian acquiescence without compensation in March 1909); and finally the two Balkan Wars of 1912--1913, in which Serbia conquered Macedonia and Kosovo from the Ottoman Empire and drove out Bulgaria . </P> <P> Serbia's military successes and Serbian outrage over the Austro - Hungarian annexation of Bosnia - Herzegovina emboldened Serbian nationalists in Serbia and Serbs in Austria - Hungary who chafed under Austro - Hungarian rule and whose nationalist sentiments were stirred by Serb "cultural" organizations . In the five years leading up to 1914, lone assassins--mostly Serb citizens of Austria - Hungary--made a series of unsuccessful assassination attempts in Croatia and Bosnia - Herzegovina against Austro - Hungarian officials . The assassins received sporadic support from Serbia . </P> <P> On 15 June 1910, Bogdan Žerajić attempted to kill the iron - fisted Governor of Bosnia and Herzegovina, General Marijan Varešanin . Žerajić was a 22 - year - old Orthodox Serb from Nevesinje, Herzegovina, who was a student at the Faculty of Law at the University of Zagreb and made frequent trips to Belgrade . (General Verešanin went on to crush the last Bosnian peasant uprising in the second half of 1910 .) The five bullets Žerajić fired at Varešanin and the fatal bullet he put in his own brain made Žerajić an inspiration to future assassins, including Princip and Princip's accomplice Čabrinović . Princip said that Žerajić "was my first model . When I was seventeen I passed whole nights at his grave, reflecting on our wretched condition and thinking of him . It is there that I made up my mind sooner or later to perpetrate an outrage ." </P>
