Fissures began to form in the party following the rise of Michael Witte, splitting the party into "big tent centrist" faction, the left-wing "Urcean mode Marxists" party, and the Wittonian Socialist faction. The party dissolved as part of the 2015 Urcean political realignment and is considered to have been legally succeeded by the Union for National Solidarity founded by the Wittonian faction.
