A united front is an alliance of
left-wing working-class organizations. Historically, a united front referred to tactical alliances between
social-democratic and
Communist parties. While each affiliate of this front remains independent, they work together around common issues (most often through work in mass organizations such as
labor unions). While working together with social democrats and other reformists on everyday issues, Communists inside a united front would continue to promote a revolutionary platform. A united front differs from a
popular front, an alliance that also contains moderate
middle-class and
upper-class parties.
