Revolutionary Socialist Party

The Revolutionary Socialist Party (, , or PSR) was a small left-wing party in Portugal, founded in 1978 after the merger of two Trotskyist parties: the Internationalist Communist League ( LCI) and the Workers Revolutionary Party (, PRT). The LCI and PRT were both part of the reunified Fourth International. The International recognised the PSR as its Portuguese section. In 1998 Party renamed itself in order to join with some other left-wing parties in founding the Left Bloc (Portuguese: Bloco de Esquerda or BE). The organisation retains the acronym PSR, and has become the association "Revolutionary Socialist Politics". The historical leader of the PSR is Francisco Louçã, who would become leader of the Left Bloc. The party had never achieved parliamentary representation before the merger in the Left Bloc, although it may be considered the 3rd or 4th biggest left-wing party in the country. In the 1970s In 1979, the Party ran in a legislative election for the first time, achieving 0.6% of the voting. In the next year, another legislative election took place and the Party achieved 1.0% of the votes.
