In The Bridge on the Drina (1945), which tells Bosnia’s history through 500 years of anecdotes centered on an Ottoman bridge in the town of Višegrad (Basil Davidson called the novel ‘Bosnia’s Waverley’), Ivo Andrić wrote of the persecution of ethnic Serbs by Austrio-Hungarian authorities and their Muslim backers after Gavrilo Princip assassinated Archduke Franz Ferdinand in 1914: As has so often happened in the history of man, permission was tacitly granted for acts of violence and plunder, even for murder, if they were carried out in the name of higher interests, according to established rules, and against a limited number of men of a particular type and belief. Saturday, 11 July was the 20th anniversary of the start of the slaughter of 8000 Bosnian Muslims in Srebrenica, ninety kilometres north of Višegrad.
