Panhispanism is a political trend aimed to achieve social, economic, and political cooperation (at the extreme, unification) of the Spanish-speaking countries, principally those of Hispanic America, due to the distance between Spain, Western Sahara and Equatorial Guinea. It focuses principally on the former Spanish Empire's territories in North, Central and South America. It has been present consistently in literature, revolutionary movements, and political institutions. The term may be also used to talk specifically about projects of Hispanic American unity held by Simón Bolívar and José de San Martín.
