The PSL was formed when the San Francisco branch and several other members left the Workers World Party in June 2004, announcing that "the Workers World Party leadership is no longer capable of fulfilling mission" of building socialism.

Historically, the PSL has a generally positive view of the Soviet Union, describing the October Revolution as "the single biggest event that shaped global politics in the 20th century".
