Answer:
The 19th Century Independence movements in Latin America led to the creation of numerous independent countries.
Step-by-step explanation:
Most countries were fighting against the rule of the mighty Spanish Empire which had colonized the region for several centuries.
However a couple of countries were also fighting against the Portuguese.
By the end of the 19th century, many nations came into being including, Colombia, Peru, Argentina, Chile, Ecuador, Bolivia and many others.
The new young countries were still vulnerable to outside influence and as Spanish power declined, many other European nations were waiting to fill the power vacuum.
In response, the United States developed the Monroe Doctrine, stating how it will not tolerate any interference of European countries in the Western Hemisphere.
