Guaviare (Spanish pronunciation: [ɡwaˈβjaɾe]) is a department of Colombia. It is in the southern central region of the country. Its capital is San José del Guaviare. Guaviare was created on July 4, 1991, by the new Political Constitution of Colombia. Up until that point, it was a national territory that operated as a commissariat, segregated from territory of the then Commissariat of Vaupés on December 23, 1977. From Wikipedia
