Eduardo Dato e Iradier (12 August 1856 – 8 March 1921) was a Spanish political leader during the Spanish Restoration period. He served three times as Spanish prime minister: from 27 October 1913 to 9 December 1915, from 11 June 1917 to 3 November 1917, and from 28 April 1920 until his assassination by Catalan anarchists. Also he held eleven cabinet ministries, and was four times president of the Spanish Congress of Deputies (a role akin to that of parliamentary speaker).
