This party was one of the last political movements linked to the figure of President Carlos Ibáñez del Campo.

After the 1973 coup d'etat, PADENA entered in political recess and some of its members served in public offices during the military dictatorship.

On 31 January 1986 the faction led by Parra was part of the Frente Democrático de Concordia (FREDECO) along with the Social Democracy Party, the Radical Democracy, the Social Christian Movement, the Radical Civic Union, the Social Democratic Labour Movement, the Javiera Carrera Movement and the Arturo Matte Civic Center.

On 2 February 1988, it signed the statement of formation of the Concertación, but it did not get the number of signatures required for its legalisation and was disbanded by the Electoral Service on 12 September of that year.

[2] The PADENA emblem was a rectangular white flag with navy blue trim, and in the center of this a red anvil appeared.
