No one event was the actual cause of the revolution. It was, instead, a series of events that led to the war. Essentially, it all began as a disagreement over the way Great Britain treated the colonies versus the way the colonies felt they should be treated.

The reasons why the United States provided loans for the Latin American countries after they gained independence from Spain were mostly of economic and political interests.
By providing loans to these newly formed nations, the United States tried to create a positive opinion by the people in these nations about them, as they would have thought that the United States are helping them to develop. The real reason why the loans were granted though was to make these nations economically dependent and connected with the United States, thus the United States to have big power over them. Also, because this is a region in the neighborhood of the United States, they wanted to make sure that they would have things under control, create good relations with these nations, and avoid any future problems.
