"The reverberations of Princip's shots truly shook the world. Yet political assassinations were far from uncommon in the early twentieth century, as we have already seen in the case of the unfortunate President McKinley. His successor, Theodore Roosevelt, only narrowly escaped assassination too. Between 1900 and 1913 no fewer than forty heads of state, politicians and diplomats were murdered, including four kings, six prime ministers and three presidents. In the Balkans alone there were eight successful assassinations, the victims of which included two kings, one queen, two prime ministers and the commander-in-chief of the Turkish Army."
