The AN-PG used the estreleira as its flag and organized protests on July 25, considered as "Día Nacional de Galicia" or the "Day of the Galician Fatherland".

After the municipal elections of 1979, the AN-PG was restructured to promote greater coordination among its counselors, creating local assemblies.

In 1981 it suffered a major internal crisis that marked the celebration of V Plenary in March 1982, which led to the departure of the organization of two members of the National Direction and a group of 50 militants.

The AN-PG was opposed to the introduction of a Statute of Autonomy for Galiza, that was considered a colony that had to achieve sovereignty through constitutional grounds.

The Cultural Front of the AN-PG was one of the most active sections of the Assembly, with members like Darío Xohán Cabana, Manuel María, Emiliano Picouto or Xesús Vázquez.
