Dilma Vana Rousseff (Brazilian Portuguese: [ˈdʒiwmɐ ˈvɐ̃nɐ ʁuˈsɛf(i)]; born 14 December 1947) is a Brazilian economist and politician who served as the 36th president of Brazil from 2011 until her impeachment and removal from office on 31 August 2016. She is the only woman to have held the Brazilian presidency. Since March 2023, she has been the Chair of the New Development Bank. She also served in the cabinet of Luiz Inácio Lula da Silva during his first presidency—first as Minister of Mines and Energy, from 2003 to 2005, then as Chief of Staff from 2005 to 2010.
Rousseff was raised in an upper middle class household in Belo Horizonte. She became a socialist in her youth. After the 1964 coup d'état she joined left-wing and Marxist urban guerrilla groups that fought against the military dictatorship. Rousseff was captured, tortured, and jailed from 1970 to 1972.
