↑The Spanish Constitution does not establish any official name for Spain, even though the terms España (Spain), Estado español (Spanish State) and Nación española (Spanish Nation) are used throughout the document. Nonetheless, the Spanish Ministry of Foreign Affairs established in an ordinance published in 1984 that the denominations España (Spain) and Reino de España (Kingdom of Spain) are equally valid to designate Spain in international treaties. This term, Kingdom of Spain, is widely used by the government in national and international affairs of all kind, includuing foreign treaties as well as national official documents, and is therefore recognized as the official name by many international organisations.
