The background of the formation of PUD was the changed political situation in Central America at that period, following the end of the Cold War.

189-93 of the National Congress (the Honduran parliament) of 1 October 1993, the state of Honduras legally recognised the PUD.

That act was a follow-up of the Esquipulas Accords, by which the Central American governments agreed to give the revolutionary groups in the region possibilities to organize legally and participate in the political process.

92-94 of the National Election Tribunal of 28 January 1994, gave the PUD recognition as the fifth legally recognized political party in Honduras.

Within PUD there are two currents recognized by the National Election Tribunal, Pueblo Unido and Convergencia Popular.

In total, one congressional deputy, one member of PARLACEN (the Central American parliament), one mayor and 21 municipal councillors were elected on behalf of UD.
