Leopold II of Belgium
On 15 November 1902, Italian anarchist Gennaro Rubino attempted to assassinate Leopold, who was riding in a royal cortege from a ceremony at Saint-Gudule Cathedrale in memory of his recently deceased wife, Marie Henriette. After Leopold's carriage passed, Rubino fired three shots at the procession. The shots missed Leopold but almost killed the king's Grand Marshall, Count Charles John d'Oultremont. Rubino was immediately arrested and subsequently sentenced to life imprisonment. He died in prison in 1918.
