the Monroe Doctrine
the Monroe Doctrine
The Monroe Doctrine did not change the world. When it was issued in 1823, the United States was not strong enough to enforce it. America's foreign policies with regard to the Western Hemisphere are often cited as having roots in this doctrine. The fact is, as with all nations, its foreign affairs are dictated by what is seen as the best method to protect itself, and its allies. What the Monroe Doctrine did do, however, was to make a bold statement about how America felt about European affairs in the western hemisphere.
In reality, the Monroe Doctrine expanded on the foreign policy of Washington. Washington wanted the British to stay out of the western hemisphere. Monroe wanted all foreign powers to stay out.

Monroe's most memorable achievement is the Monroe doctrine which warned European countries not to interfere in the Western hemisphere.
Well, the Roosevelt Corollary stated that the United States would pay off the debts of Latin American countries in order to keep Europe out. Roosevelt feared that European powers would loan money to these countries and thus become involved in the western hemisphere (a violation of the Monroe Doctrine). Because of this, this was an extension of the Monroe Doctrine, and became a part of the US foreign policy.The Roosevelt corollary is important because it added to the Monroe Doctrine in matters of foreign military actions.
The Roosevelt Corollary expanded America's role in Central America and the Caribbean.
The United States turned away from its policy of isolationism
President Monroe passed the Monroe Doctrine because he was afraid of too much European involvement in Middle and South America. The US feared new involvement of European powers in the Americas -- first of France after Napoleon's victories, then of the Allied powers after Napoleon's defeat who had sworn to uphold, if necessary, by force, the power of monarchs wherever it was threatened. The Monroe doctrine expressly excluded the already existing involvement of Europe's colonial powers, but it drew the line there: every new 'colonial' effort or any armed intervention to change or forcibly retain the status quo would be actively resisted by the USA.
