The islands were sighted by early European navigators, and in 1589 the governor of the Venezuelan province ordered the formal takeover of these islands on behalf of the colony. The Dutch considered Los Roques to belong to their island territory of Curaçao because of its proximity to Bonaire which also belonged to the Dutch. The author M. D. Teenstra in 1836 still writes (in his book The Dutch West Indies): “The Government of Curaçao also includes the uninhabited islets and rocks Little Curaçao, Aves, Roques and Orchilla. ” 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.
