Olagüe's book became a cult work among certain elements of the Spanish Muslim community (most notably circles of converts), as well as Andalusian nationalist factions.
[3] The latter two agreed that the main drive behind the work is limiting any kind of "foreign" intervention in the history of Spain to the maximum extent possible, thereby inventing, in this case, the construct of a "primordial autochthonous Islam" indebted to the outside one.
In 2008, the Arabist Maribel Fierro of the Spanish National Research Council argued that Olagüe's ideology, which is linked to the origins of fascism in Spain, remains influential in contemporary historiographical debate.
This is partly the result of its diffusion and discussion in certain Internet forums, where the preference that some of its cultivators have for everything to do with conspiracy theories and whatever puts received knowledge into question is well known".
