Umberto I (Umberto Rainerio Carlo Emanuele Giovanni Maria Ferdinando Eugenio di Savoia; 14 March 1844 – 29 July 1900) was King of Italy from 9 January 1878 until his assassination in 1900. His reign saw Italy's expansion into the Horn of Africa, as well as the creation of the Triple Alliance between 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, although his ambitions over Ethiopia were left unfulfilled following the disastrous Battle of Adwa in 1896.
Domestically, Umberto faced increasing social unrest and serious economic difficulties. Tensions mounted as a result of public opposition to Italy's colonial wars, the spread of socialist ideas, and crackdowns on civil liberties. He was deeply loathed in leftist circles for his conservatism and his support of the Bava Beccaris massacre in Milan, in which demonstrations over rising food prices were violently suppressed by the military. He was particularly hated by Italian anarchists, who attempted to assassinate him during the first year of his reign. In 1900, two years after the Bava Beccaris massacre, Umberto was killed in Monza by Italian-American anarchist Gaetano Bresci. He was succeeded by his son, Victor Emmanuel III.
The son of Victor Emmanuel II and Archduchess Adelaide of Austria, Umberto was born in Turin, which was then capital of The Kingdom of Piedmont-Sardinia, on 14 March 1844, his father's 24th birthday. His education was entrusted to, among others, Massimo Taparelli, Marquess d'Azeglio, and Pasquale Stanislao Mancini. As Crown Prince, Umberto was distrusted by his father, who gave him no training in politics or constitutional government, and he was brought up with no affection or love.
