Republican Party of the Social Order
The Republican Party of the Social Order is a political party in Brazil, founded in 2010, and officially recognized in 2013.
In the 2018 Brazilian general election, PROS allied with the Workers Party and the Communist Party of Brazil to support the Presidential pre-candidacy of former President Luiz Inácio Lula da Silva and former Mayor of São Paulo Fernando Haddad. After Lula was declared ineligible to contest the election, PROS supported Haddad and his running mate Manuela d'Ávila as part of the alliance "The People Happy Again," remaining allied with PT and PCdoB.
