[2] It aimed to overturn the effects of the devastation caused by the Spanish Civil War by carrying out in Spain functions similar to those of the Istituto per la Ricostruzione Industriale (IRI) in Italy.
To achieve its goal, INI either financed on its own or directed private funds to the creation of the country's fundamental industries under the spirit of the national interest and autarky.
INI included a broad range of companies, from heavy and basic industries to "soft" services, most of them with E.N., standing for Empresa Nacional (National Corporation), in their names.
In the mid-to late 1970s, HUNOSA [es] (Hulleras del Norte S.A.), a large Asturian coal mining conglomerate, and Compañía Transatlántica Española (CTE) were among the non-functional companies that were integrated into the Instituto Nacional de Industria.
The new company named TENEO [es], which was founded on July 4 of the same year, merged into Sociedad Estatal de Participaciones Industriales (SEPI) in 1996 and the latter has practically disposed the totality of its owned shares with the exception of HUNOSA and a few other industries.
