United Left (Italian: Sinistra Unita) is a leftwing political alliance in San Marino. It was formed by Sammarinese Communist Refoundation and Zona Franca, a split from the Party of Socialists and Democrats.

The United Left ("Vereinigte Linke") was an alliance of several leftist oppositionals in the German Democratic Republic.Among them were christian socialists,trotskyists,adherents of the titoistic system of self-management and some SED-members,who were critical of their party's policy.It was founded on October 2nd ,1989,only a few weeks before the fall of the Berlin Wall.The United Left demanded a reformation of socialism.Its goal was to try creating a free and democratic GDR.At the end of the year 1989 the party had 1500 members with focal points in Berlin and Halle.In contrast to other East German oppositional groups,the United Left was less supported by the Western governments and parties.There were also organizational problems and internal controversies between the different ideological tendencies within the United Left.Those are the main reasons the party never gained much attention in politics. At the first free elections in the GDR in March 1990 the United Left started together with "Die Nelken" ("The Carnations"),a marxist party.The electoral alliance with the name "Aktionsbündnis Vereinigte Linke" gained 0.18% of the votes and one seat in the Volkskammer.The United Left fell apart in the years after German reunification,but some members were elected into the Bundestag trough a party-list by the PDS or The Greens.
