Nicholas II of Russia
On 1 March 1881, following the assassination of his grandfather, Tsar Alexander II, Nicholas became heir apparent upon his father's ascension as Alexander III. Nicholas and his other family members bore witness to Alexander II's death, having been present at the Winter Palace in Saint Petersburg, where he was brought after the attack. For security reasons, the new tsar and his family relocated their primary residence to the Gatchina Palace outside the city, only entering the capital for various ceremonial functions. On such occasions, Alexander III and his family occupied the nearby Anichkov Palace.
Vlado Chernozemski
As King Alexander's motorcade drove at a few miles per hour down a Marseille street in front of an adoring crowd, Chernozemski was able to emerge from the crowd, approach the king's car and leap onto its running board while concealing his Mauser C96 automatic pistol in a bouquet of flowers and chanting ""Vive le roi"" ("long live the king"). He shot Alexander repeatedly, hitting him twice, once in the abdomen and the other in the heart; King Alexander died within minutes. The chauffeur—who tried to push Chernozemski off the car—and Alexander's companion in the car, French Foreign Minister Louis Barthou, were also shot. Chernozemski killed the chauffeur, apparently unintentionally. A police officer fired at Chernozemski but missed and fatally wounded Barthou. The chauffeur died almost immediately, with his foot pressed on the brake of the car, providing the opportunity for a photographer outside the car to photograph most of the grisly affair. Barthou might have survived, but did not, apparently because of inadequate medical attention.
