Galician Socialist Youth (MSG, Mocidade Socialista Galega in Galician language), was a youth political organization founded on April 25, 2009 in the city of Santiago de Compostela, that acted as the youth of the Galician Socialist Space. The organization self-dissolved and transformed itself in the Galician Nationalist Youth (MNG) in November 2010.
The MSG was integrated in Galiza Nova and the Galician Nationalist Bloc. In 2009 the organization presented a candidacy, called Entre tod@s, Galiza Nova,[1] in the National Assembly of Galiza Nova to the National Direction. The candidacy got the 20% of the vote and 5 seats in the National Direction.[2] The main goal of the MGS inside Galiza Nova was to change the organization[3] and to decrease the power that the Galician People's Union had inside the organization.
