Sebastián Piñera, Chilean businessman and politician, 35th President of Chile
Miguel Juan Sebastián Piñera Echenique OMCh (Spanish: [miˈɣel ˈxwan seβasˈtjam piˈɲeɾa etʃeˈnike] (listen); born 1 December 1949) is a Chilean billionaire businessman, politician who served as president of Chile from 2010 to 2014 and again from 2018 to 2022.

The son of a Christian Democratic politician and diplomat, he studied business engineering at the Pontifical Catholic University of Chile and economics at Harvard University. He had an estimated net worth of 2.8 billion dollars in 2019 according to Forbes, making him one of the richest people in Chile.A member of the liberal conservative National Renewal party, he served as a senator for the East Santiago district from 1990 to 1998, running for the presidency in the 2005 election, which he lost to Michelle Bachelet, and again, successfully, in 2010. As a result, he became Chile's first conservative president to be democratically elected since 1958, and the first to hold the office since the departure of Augusto Pinochet in 1990.Following the social unrest that erupted in late 2019, Piñera's diminished capacity to govern according to the principle of presidentialism has led to claims that Chile is in a state of de facto parliamentarism or should become parliamentarian.
