democracy. PSB proposed to be a party of "everyone who relies on their own work". It advocated immediate reforms, such as the nationalisation of economically strategic areas, the expansion of workers' rights, the ensuring of public health and education, and the development of democracy through means of popular participation. Its structure brought a new experience which characterised PSB's democratic profile: the Base Centres (núcleos de base). Through them, Socialist militants could get involved in the party project, discuss national issues and form the orientation and the target of partisan action. In the 1950 election, PSB's candidate, João Mangabeira won only 0.12% of the vote and the PSB elected only one deputy from Sergipe. At the same time, the PSB approached the PCB, banned in 1947 and operating underground. A number of communists ran for office under the PSB's endorsement. In the 1955 election, the PSB endorsed the UDN candidate, Juarez Távora. In São Paulo, the PSB supported the electoral endeavors of Jânio Quadros: first in the São Paulo mayoral election in 1953 and Quadros' successful bid for Governor in 1954.

Most Socialists joined the Brazilian Democratic Movement (MDB), the only opposition party recognised by the military regime. Following the fall of the military in 1985, a number of former PSB members joined the Democratic Labour Party or the Workers' Party (PT). Second PSB (1989–present) Following the return to a democracy in the country, a Brazilian Socialist Party was re-organised on the 1947 manifesto. At first, it achieved limited electoral success, though it elected some legislators and mayors. In the 1989 presidential election, it supported the PT candidate, Luís Inácio Lula da Silva. In 1990, Pernambuco Governor Miguel Arraes joined the party, giving the PSB a certain electoral boost in subsequent elections. In the 1994 election, the party again endorsed Lula. In the same election, Arraes
