Although Spain is an imperialist country, foreign countries own a large share of the monopolies there. MIM is still studying whether a majority of the population there is petty-bourgeoisie or not.
Spain is important as a place where major powers fought the first battles of World War II. In the Spanish Civil War of 1936-38, the Nazis aided Franco to destroy the elected republic while Stalin sent weapons to defend the republic against fascist treason. Anarchists also consider Spain important, because anarchists seemed to be in control of about 4 million people for a period of the civil war, the best showing of anarchists anywhere in the modern world.
