Unión do Povo Galego
ERGA was founded on the initiative of the Galician People's Union (UPG), in a climate of tension that followed the strikes at the University of Santiago de Compostela and the death of a student, Chema Fuentes, by the police in December 1972. The initiative was commissioned to Manuel Mera, that had just arrived from Argentina and knew the experience of the Maoist Communist Vanguard university organization, that had to organize an organization that could put together university and high school students.
