Monroe Doctrine
As the Spanish Empire continued to fracture during Monroe's second term, Adams, Monroe and Clay became increasingly concerned that the "Holy Alliance" of Prussia, Austria, and Russia would seek to bring Spain's erstwhile colonies under their control, to the point of even contemplating a Holy Alliance of their own to defend democracy. In his 1821 Fourth of July address, Adams addressed this issue, noting a shared "chain of sympathy" between the U.S. and Latin America, but arguing for neutrality rather than a Holy Alliance.[82] In 1822, following the conclusion of the Adams–Onís Treaty, the Monroe administration recognized the independence of several Latin American countries, including Argentina and Mexico. In 1823, British Foreign Secretary George Canning suggested that the United States and Britain should work together to preserve the independence of these fledgling republics. The cabinet debated whether to accept the offer, but Adams opposed it. Instead, Adams urged Monroe to publicly declare the United States' opposition to any European attempt to colonize or re-take control of territory in the Americas, while also committing the United States to neutrality in European affairs.
