In 1970 AC came in contact with workerist organizations like UHP and CRAS (Comunas Revolucionarias de Acción Socialista).

After an unsuccessful process of merger with the POUM, AC held a congress of self-dissolution in 1978.

AC didn't practice democratic centralism and was influenced by Situationism, Council communism and Luxemburgism.

Among the most relevant authors for AC there were: Clara Zetkin, Rosa Luxemburg, Otto Rühle, Andreu Nin, Alexandra Kollontai, Trotsky, Joaquim Maurín, Karl Korsch, Paul Mattick, Anton Pannekoek, Claude Lefort, Cornelius Castoriadis, Guy Debord, etc.

There were rigid criteria for the selection of aspiring militants and it was necessary to go through an initiation process to be able to belong to the association.
