On a summer morning in Sarajevo a hundred years ago, a teenage assassin named Gavrilo Princip fired not just the opening shots of the First World War but the starting gun for modern history, when he killed Archduke Franz Ferdin&. Yet the events Princip triggered were so monumental that his own story has been largely overlooked, his role garbled & motivations misrepresented. The Trigger puts this right, filling out as never before a figure who changed our world & whose legacy still has an impact on all of us today. Born a penniless backwoodsman, Princip`s life changed when he trekked through Bosnia & Serbia to attend school. As he ventured across fault lines of faith, nationalism & empire, so tightly clustered in the Balkans, radicalisation slowly transformed him from a frail farm boy into history`s most influential assassin. By retracing Princip`s journey from his highland birthplace, through the mythical valleys of Bosnia to the fortress city of Belgrade & ultimately Sarajevo, Tim Butcher illuminates our understanding both of Princip & the places that shaped him. Tim Butcher uncovers details about Princip that have eluded historians for a century & draws on his own experience, as a war reporter in the Balkans in the 1990s, to face down ghosts of conflicts past & present. The Trigger is a rich & timely work that brings to life both the moment the world first went to war & an extraordinary region with a potent hold over history.
