Much of Spain's economy was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%, but lower in areas with heavy Communist Party of Spain influence, as the Soviet-allied party actively resisted attempts at collectivization enactment. Factories were run through worker committees, agrarian areas became collectivised and run as libertarian communes. Anarchist historian Sam Dolgoff estimated that about eight million people participated directly or at least indirectly in the Spanish Revolution,[132] which he claimed "came closer to realizing the ideal of the free stateless society on a vast scale than any other revolution in history."[133]
