Ruedo ibérico embarked on a process of uncovering where Spain’s recent history occupied pride of place. The publication of The Spanish Civil War and The Spanish Labyrinth deconstructed the clumsy lies and historical myths imposed by the regime by comparing them to documented studies. The publishing house also tackled general subjects like the worker’s movement, the military, the Falange, the participation of Spanish people on the side of the allies during the Second World War, as well as subjects silenced by the dictatorship such as the assassination of Lorca or the siege of the Alcázar of Toledo and that of Madrid. There were also published testimonies such as those by Mera, García Oliver, Borkenau and Koltsov’s diaries.

Ruedo ibérico published works of an academic nature, but did not dismiss interpretations with an evident ideological imprint within the vast spectrum extending from García Venero’s crumbling Falange, to books by the founders of the POUM Andrés Nin and Joaquín Maurín, via the republicanism of Borras and the libertarian anarchism of Peirats.
