Socialist Party (Gylias)
|National affiliation||Progressive Alliance|
Established in 1903, it is one of Gylias' oldest left-wing parties. It has been among the standard-bearers for Gylian socialism, playing a significant role in the Gylian ascendancy and a central one in the Popular Progressive Front that governed Alscia.
The Socialist Party was founded in 1903, as a leftist breakaway from the underground Social Democratic Party during the royal dictatorship period. After the Cacerta-Xevden War, it moved its headquarters to Alscia.
As part of the Popular Progressive Front, it was one of the major leftist parties together with the Social Democratic Party, both representing the interests of workers. It was more radical and sympathetic to the syndicalist tendency in the labour movement.
Despite liberals' image of undisputed dominance, strong internal competition occurred within the FPP, with the leftists gradually gaining ground at the expense of the liberals due to Alscia's radicalisation.
In the Free Territories, the SP gained something of a big tent nature as other left currents joined it, particularly to better coordinate in the General Council. These currents would later leave during the de-factionalisation triggered by the Law on Electoral Representation of 1960.
After the 1958 federal election, it formed an alignment with the Democratic Communist Party and Social Democratic Party, the latter a coalition partner in the former FPP, which became the Progressive Alliance. In the Darnan Cyras government, it was mainly represented by education ministers Rin Tōsaka and Sakura Tōsaka, health minister Régine Walras, and planning minister Theophania Argyris.
The loss of expected successor Aliska Géza before the 1976 federal election threw the PA into disarray, and it tied the Revolutionary Rally for first place. Participating in a coalition with the RR was a highly controversial topic, and during the wretched decade the SP was torn by factional battles between "coalitionists" and "oppositionists". It joined Filomena Pinheiro's grand coalition cabinet after the Ossorian war crisis of 1986.
During the 1990s, the SP took an ambiguous stance towards Mathilde Vieira's "plural coalition" — formally outside it, but with one cabinet member from the party. The alliance with the Liberal Union was rebuilt under Kaori Kawashima, and the PA returned to a leading role in the Toni Vallas government, before moving to opposition in 2020.
The SP uses the colour red as its official colour, and the Three Arrows as its electoral symbol.
