Socialist Party (Sweden) (1814: Norwegian Independence)

The Socialist Party (Swedish: Socialistiska partiet, SP) is a socialist political party in Sweden. The party was formed under the reign of the Swedish military regime as the Workers' Resistance Front (Arbetares Motståndsfront), a communist group active in sabotage and assassinations against the regime.

After the regime, the party changed its name to the Workers' Communist League (Arbetaranes Kommunistliga), and began to participate in democratic elections. But the party was still sometimes involved in violent actions against former members of the NPA. The party did also have strong ties with the Soviet Union before the end of the cold war.

In 1992, the party changed to what it is today, following a shift of the party from communism to socialism.
