Concept
Carlos Diego de Mesa Gisbert (ˈkaɾlos ˈðjeɣo ˈmesa xisˈβeɾt; born 12 August 1953) is a Bolivian historian, journalist, and politician who served as the 63rd president of Bolivia from 2003 to 2005. As an independent politician, he previously served as the 37th vice president of Bolivia from 2002 to 2003 under Gonzalo Sánchez de Lozada and was the international spokesman for Bolivia's lawsuit against Chile in the International Court of Justice from 2014 to 2018. A member of the Revolutionary Left Front, he has served as leader of Civic Community, the largest opposition parliamentary group in Bolivia, since 2018. Born in La Paz, Mesa began a twenty-three-year-long journalistic career after graduating from university. He rose to national fame in 1983 as the host of De Cerca, in which he interviewed prominent figures of Bolivian political and cultural life. His popular appeal led former president Gonzalo Sánchez de Lozada of the Revolutionary Nationalist Movement (MNR) to invite him to be his running mate in the 2002 presidential election. Though Mesa's moderate left-wing sympathies contrasted with centre-right policies of the MNR, he accepted the offer, running as an independent in a hotly contested electoral campaign. The Sánchez de Lozada-Mesa ticket won the election, and, on 6 August, Mesa took charge of a largely ceremonial office that carried with it few formal powers save for guaranteeing the constitutional line of succession. Shortly into his term, conflict between Sánchez de Lozada and Mesa arose. By October 2003, the increasingly tense situation surrounding the ongoing gas conflict caused a definitive break in relations between the president and vice president, leading the latter to announce his withdrawal from government after clashes between protesters and military personnel led to several deaths. Crucially, Mesa opted not to resign from his vice-presidential post and succeeded to the presidency upon Sánchez de Lozada's resignation.
