salt mines and guano began. Independent Venezuela In 1871 the Venezuelan president Antonio Guzmán Blanco created by decree the Territorio Colón (Columbus Territory) which included Los Roques and other adjacent islands. The island of Gran Roque was named as the center of territorial government. Around the year 1886 there is reference to the arrival of inhabitants coming from the nearby Netherlands Antilles, Aruba, Curaçao, etc. They left as a legacy some of the exotic names given to some islands or keys (for example Francisquí, Madrisquí, Krasquí, Selesquí). The suffix "quí" corresponds to the English term (and other languages) "key", which means Island. At the beginning of the 20th century an epidemic of bubonic plague in La Guaira caused the Venezuelan government to authorize the use of the island of Gran Roque as a quarantine site. In 1910, the town of Gran Roque began to consolidate with families from Margarita Island, mainly fishermen. On 20 July 1938 the islands were integrated into the Federal Dependencies of Venezuela, and it was only on 8 August 1972 that the archipelago was declared a national park. The small population of 484 that inhabited it in 1941 grew to 559 in the year 1950. After its declaration as a national park, the Los Roques scientific foundation (Fundación Científica de Los Roques) was created, which established its laboratories and facilities on the island of Dos Mosquises, to carry out works on archeology, fish, turtles, mollusks, corals, sponges, fishing and oceanography. In 1978 the marine delimitation agreement between Venezuela and the Kingdom of the Netherlands was signed. In 1987, the Los Roques Scientific Foundation carried out a registry, which allowed them to conclude that there were 847 inhabitants in Gran Roque. Only 663 of these were permanent inhabitants, and the remainder were sailors residing on Isla Margarita. Autonomy In order to give greater dynamism to its administration and promote the sustainable development of the islands on 2 November 1990, according to Presidential Decree 1214, the figure of the Single Authority of Los Roques Area (Autoridad Única de Área) was created, which would continue as part of the Federal Dependencies but with a special administrative status. In October 2011 all the islands of the Los Roques archipelago are integrated to the Miranda Insular Territory (Territorio Insular Francisco de Miranda) according to presidential decree 8549 of 1 November 2011, published in the official gazette N° 39797, a subdivision of
