The Constitution of 1999 was the first constitution approved by popular referendum in Venezuelan history, and summarily inaugurated the so-called "Fifth Republic of Venezuela" due to the socioeconomic changes foretold in its pages, as well as the official change in Venezuela's name from the "República de Venezuela" ("Republic of Venezuela") to the "República Bolivariana de Venezuela" ("Bolivarian Republic of Venezuela"). Major changes are made to the structure of Venezuela's government and responsibilities, while a much greater number of human rights are enshrined in the document as guaranteed to all Venezuelansincluding free education up to tertiary level, free health care, access to a clean environment, right of minorities (especially indigenous peoples) to uphold their own traditional cultures, religions, and languages, among others. The 1999 Constitution, with 350 articles, is among the world's longest, most complicated, and most comprehensive constitutions.
