Portuguese politician and military officer. Prime Minister of Portugal. Between 1904 and 1918, he was a professor at the Military Academy, where he taught artillery tactics. He also taught English at the Military College from 1905 to 1913. During World War I, Ivens Ferraz was appointed chief liaison officer of the Portuguese Expeditionary Corps (CEP) with the British army in France, in 1917. Previously, he headed a military mission to the War Office at the outbreak of the war (1914) and held other senior positions in the CEP. From 1919 to 1922 he was military attaché in London. Between 1924 and 1926 he served as head of the office of the High Commissioner of Mozambique, Victor Hugo de Azevedo Coutinho, and from May to November 1926 as acting High Commissioner and Governor-General. During the Military Dictatorship, in the government led by General Carmona, he served as Minister of Commerce and Communications (from August 1927 to January 1928), Minister of the Colonies (from January to February 1928) and interim Minister of Finance (from February to April 1928). In this latter capacity, he went to Geneva to negotiate a large foreign loan under the auspices of the League of Nations, but ultimately rejected the conditions attached to it, considering them offensive to national sovereignty. On his return to Lisbon, he was received in triumph. Promoted to General in 1928, Ivens Ferraz was appointed Prime Minister by then President Carmona on July 8, 1929, holding office until January 21, 1930. He also temporarily took over the ministries of Foreign Affairs, Internal Administration and Education. A conservative republican, he favoured a return to constitutional normality, although not immediate. His differences over the future of the regime with the Finance Minister, Salazar, who defended an authoritarian model, eventually led to the fall of the government. After leaving office, he returned to his previous post as General Administrator of the Army and, in 1931, was appointed Chief of Staff of the Army, a position he held until his death in 1933, three months before the implementation of the Estado Novo (New State), an autocratic dictatorship led by Salazar.
