hints：Monroe Doctrine;James Monroe
The Americans won important battles on land and sea. Weakened and in debt from its recent war with France, Britain signed a peace treaty with the U.S. in 1815. The U.S. victory made sure that Britain wouldn't establish colonies south of the Canadian border. By 1815, many of the new nation's problems had eased. Under the constitution, the United States had a balance between liberty and order. The country had a low national debt. Much of the continent was left to explore. The country had peace, prosperity, and social progress. An important addition to foreign policy was the Monroe Doctrine. President James Monroe's announcement of solidarity with newly independent nations in Central and South America was a warning to Europe not to seek colonies in Latin America.
