  Historically, the Hispanic countries were founded as Republican dictatorships led by caudillos. Brazil was the only exception, being a constitutional monarchy for its first 67 years of independence, until a coup d'état proclaimed a republic. In the late 19th century, the most democratic countries were Brazil, Chile, Argentina and Uruguay.
  
  All South American countries are presidential republics with the exception of Suriname, a parliamentary republic. French Guiana is a French overseas department, while the Falkland Islands and South Georgia and the South Sandwich Islands are British overseas territories. It is currently the only inhabited continent in the world without monarchies; the Empire of Brazil existed during the 19th century and there was an unsuccessful attempt to establish a Kingdom of Araucanía and Patagonia in southern Argentina and Chile. Also in the twentieth century, Suriname was established as a constituent kingdom of the Kingdom of the Netherlands and Guyana retained the British monarch as head of state for 4 years after its independence.
  
  Recently, an intergovernmental entity has been formed which aims to merge the two existing customs unions: Mercosur and the Andean Community, thus forming the third-largest trade bloc in the world. This new political organization, known as Union of South American Nations, seeks to establish free movement of people, economic development, a common defense policy and the elimination of tariffs.
