General Archives of Puerto Rico

The General Archives of Puerto Rico was formally created by Law 5 of December 8, 1955, and placed under the Institute of Puerto Rican Culture which had been created six months before. The main function of the entity is to safeguard and conserve the most important inactive documents of Puerto Rico's territorial government, both under United States rule as well as during the 390 years of Spanish colonial government in Puerto Rico between 1508 and 1898.
