Upon the release of El Estado Nuevo, the work was unconditionally and rather enthusiastically accepted among the Carlist intellectuals as an in-depth discourse of their ideology and a guidance for the future.
Among the Spanish Right of the 1930s El Estado Nuevo made a huge intellectual impact, especially that all the competing formations, the Alfonsists from Renovacion Espanola, the Catholics from CEDA and the rapidly growing fascists from Falange were missing a comparable, detailed, integrated, visionary doctrine.
Key differences focused on the questions of monarchy, coercive powers of state and degree of social engineering.
Among the Left the vision of Pradera did not attract much attention, since Carlism and its theories were considered profoundly archaic, if not simply long dead.
In the Francoist Spain Pradera's vision was referred to with sympathy – Franco himself wrote a foreword to the 1945 edition of El Estado Nuevo – but never as an alleged theoretical foundation of the state.
