Under the Monroe doctrine the US considered South America its sphere of influence during the administration of US president Monroe in the 19th century when such thinking about spheres of influence prevailed. A closer look shows that this was a policy against restoring Spanish or French colonization of newly independent nations in South America such as Argentina, Brazil, Colombia, Peru, Chile and Mexico. It was put forth in an annual message to Congress in 1823 by president Monroe. 

It had the support of Thomas Jefferson and James Madison, founding fathers of America. Originally it was intended to be a joint British-American declaration by Canning and Monroe. In this sense even the superficial notion of America supporting such spheres of influence is based on protecting liberty of nations that suffered colonization such as Mexico, Venezuela, Peru, Argentina and gained independence from Spain.

Under president Theodore Roosevelt it was used to keep European powers from invading Venezuela in 1903 to enforce the payment of debts Venezuela had with European countries.
