On 28 June 1914, 109 years ago today, at around 11 o’clock in the morning, a 20-year-old anarchist assassin, Gavrilo Princip, fired several shots at the Archduke of the Austro–Hungarian Empire and his wife. The Sarajevo assassination became the casus belli for the ‘Great War’, as it was called back then, i.e., the First World War.
