Umberto I (Italian: Umberto Ranieri Carlo Emanuele Giovanni Maria Ferdinando Eugenio di Savoia; 14 March 1844 â 29 July 1900) was King of Italy from 9 January 1878 until his assassination in 1900. His reign saw the creation of the Italian Empire, as well as the creation of the Triple Alliance among Italy, Germany, and Austria-Hungary.
The son of Victor Emmanuel II and Adelaide of Austria, Umberto took part in the Italian Wars of Independence as a commander of the Royal Sardinian Army. He assumed the Italian throne in 1878 on the death of his father. A strong militarist, Umberto approved the alliance with Germany and Austria-Hungary, which was formalised in 1882. He also encouraged Italy's colonial efforts and oversaw the incorporation of Eritrea and Somalia into the Italian Empire.
