This book analyses the processes of revolution and state reconstruction that took place in the Republican zone during the Spanish civil war. It focuses on the radical anarchists who sought to advance the revolutionary agenda. Their activity came into conflict with the leaders of the libertarian organisations committed to the reconstruction of the Republican state following its near collapse in July 1936. This process implied participation not only in the organs of governance but also in the ideological reconstitution of the Republic as a patriarchal and national entity.

Using original sources, the book shows that the opposition to this process was both broader and more ideologically consistent than has hitherto been assumed, and that, in spite of its heterogeneity, it united around a common revolutionary programme. This resistance to state reconstruction was informed by the essential insight of anarchism: that the function and purpose of the modern state cannot be transformed from within. By situating the struggles of the radical anarchists within the contested process of state reconstruction, the book affirms the continued relevance of this insight to the study of the Spanish revolution.
