Resistência Galega is the continuation of several Galician separatist groups active in the 1970s and 80s such as the Loita Armada Revolucionaria, "Liga Armada Galega" or "Exército Guerrilheiro do Povo Galego Ceive". The organisation was reportedly created by the Assembleia da Mocidade Independentista () in 2005 and it became known to the public with a manifesto published on the internet on 20 November that same year. In it, several attacks against political party offices, the Spanish Army, and incidents which occurred during the Prestige oil spill crisis were claimed.
