A western education system was implemented, and Sarajevo's inhabitants started writing in Latin script for the first time. By 1910, Sarajevo was populated by just under 52,000 people. Just four years later the most famous event in the history of Habsburg Sarajevo, and perhaps in the city’s history, occurred. The Assassination in Sarajevo, during which a young Serb nationalist Gavrilo Princip assassinated Archduke Franz Ferdinand of Austria and his wife Sophie, Duchess of Hohenberg, on their visit to the city, started a
Emperor of Austria in 1875. As Ferdinand I had no sons, his brother Francis Charles would have become emperor, but was persuaded by his wife to pass over the right of succession to their son, Francis Joseph. He accepted the duty of the Emperor of Austria without having been Crown Prince or "Thronfolger" before. Francis Joseph's only son Rudolf committed suicide in 1889, Francis Joseph's brother Karl Ludwig died in 1896. Karl Ludwig's son Franz Ferdinand became heir presumptive to the throne. He was assassinated in Sarajevo, Bosnia in 1914; due to his morganatic marriage, his son had no rights to the throne.
