Early life and career
Early life and career
Guilherme Boulos is the son of Marcos Boulos, a professor of medicine at the University of São Paulo. He is of Lebanese Christian descent, with “Boulos” meaning “Paul” in Arabic. He graduated with a degree in philosophy in 2006 and received a master's degree in mental health in 2017, both from the University of São Paulo. In his youth he engaged in the Union of Communist Youth. He also joined the Homeless Workers' Movement in 2002. He became famous in 2003 when he participated in the coordination of the invasion of a Volkswagen's ground in São Bernardo do Campo. He appeared again in the press in 2014, in the wake of the social mobilizations around the World Cup, especially the squat called Occupation People's Cup (Ocupação Copa do Povo), organized by the MTST in early May. On 17 January 2017, Boulos was arrested on charges of committing judicial disobedience and incitement to violence during the repossession lawsuit of a plot of land in the district of São Mateus. Later that evening, he was released from prison. In his defense, he claims that his detention was arbitrary and for political reasons.
