Nationally, there are two main political parties in El Salvador with roots in the Civil War. The main right-wing party is La Alianza Republicana Nacionalista (Nactionalist Republican Alliance—ARENA), founded on September 30, 1981, retained strong links to the military during the Civil War and have held power for the later years of the war and most of the post-war period. The Farabundo Martí National Liberation Front (FMLN) the socialist party, is the direct descendant of the communist guerrilla troops that fought against the Salvadoran government, and was legally constituted as a political party on September 1, 1992. Since the Civil War the two have remained the country's principal political parties, still divided by the left-right binary.
