In your post, you have asked five questions. The policy at is to respond to one question per post. I will respond to your first question.

Between 1815 and 1824, the United States had several foreign policy objectives. One of the main objectives was to support the independence movements in Latin America. Many countries in Latin America were becoming independent from Spain and Portugal during this time. We supported the desire of these people to be free from the rule of the Europeans. There was some thought that the Europeans would try to return to the Americas to reestablish their colonies. As a result, President Monroe issued the Monroe Doctrine in 1823. This major foreign policy statement told the European countries that they would not establish any new colonies in the Americas. This statement, backed by the British who wanted to weaken their European rivals, helped to show the Europeans that the United States was growing as a force in world affairs.

The United States also pursued a policy of controlling more land in North America. We signed the Adam-Onís Treaty with Spain in 1819. This treaty gave control of Florida to the United States. In return, the United States would pay any claims the Spanish had against Americans who rebelled against Spain. This amount was about $5 million. Spain also agreed to drop its claims to the Oregon Territory, and the United States acknowledged the Spanish control of Texas.
