Irigoyen (or Yrigoyen), Hipólito (1850–1933)

Argentine politician and president 1916–22 and 1928–30. He became leader of the Radical Civic Union Party (bourgeois reformist group) in 1896 and worked for electoral reform, which, when it came in 1912, brought him to power as the first radical president, replacing the landowning oligarchy. He maintained Argentine neutrality during World War I.

During his second term his administration was plagued by severe economic depression and he was deposed by a military coup.
