Alvear, Marcelo T de

▪ president of Argentina

born October 4, 1868, Buenos Aires

died March 23, 1942, Buenos Aires

 statesman and political leader who served as president of Argentina from 1922 until 1928.

      Alvear belonged to a distinguished Argentine family. He was educated at the University of Buenos Aires, where he received a doctor of jurisprudence degree. He was a cofounder in 1890 of the Radical Civic Union (UCR), the political party representing the liberal-democratic viewpoint in Argentina. He took part in revolutions of 1890, 1893, and 1905 that helped to establish liberal democracy in Argentina; he then served as minister of public works in 1911, as a member of Parliament in 1912–17, and as Argentine ambassador to France in 1917–22.

      In 1922 Hipólito Irigoyen (Irigoyen, Hipólito), the UCR leader and president of Argentina, designated Alvear as his successor. Alvear served as president until 1928, when he broke with Irigoyen, founded the Antipersonalist Union Party, a splinter group of the UCR, and formed an alliance with many conservatives (members of the old oligarchy that opposed the UCR). Despite Alvear's opposition, Irigoyen regained the presidency in elections in 1928. Alvear rejoined the UCR after a conservative-oriented military coup overthrew Irigoyen's government in 1930. He ran for the presidency in 1931, but he was declared ineligible because less than a full term had expired since he left office.

      Alvear's publications include Acción democrática (1938; Democratic Action) and numerous state papers and public documents.
