The TWP fell out of power following the 1980 Liberian coup d'état in which many of its leading members were killed or fled, ending its dominant position. The TWP ceased to be officially recognized following the coup, although it was never disbanded and continued as a rump party. The party went on to participate in the unsuccessful Coalition for the Transformation of Liberia (COTOL) ahead of the 2005 general election before de-coalition and winning fewer votes at the 2017 elections.
