Monroe Doctrine

European colonization and intervention in the Western Hemisphere were held in check by the Monroe Doctrine.

The Doctrine that held European colonization and intervention in the Western Hemisphere in check is known as the "Monroe Doctrine."

To understand the Monroe Doctrine, it is essential to provide some background information:

1. The Western Hemisphere refers to the regions of North, Central, and South America, along with the surrounding islands.
2. In the early 19th century, many Latin American countries were gaining independence from their European colonial powers.
3. The United States, under the presidency of James Monroe, wanted to ensure that these newly independent countries in the Western Hemisphere would not be reconquered or influenced by European powers.

With this context, we can explain the Monroe Doctrine:

The Monroe Doctrine is a policy statement issued by the United States in 1823. It was articulated by President James Monroe during his annual address to Congress. The key components of the doctrine were as follows:

1. Non-Colonization: The United States would oppose any efforts by European powers to establish new colonies in the Western Hemisphere. Essentially, it declared that the American continents were no longer available for European colonization.

2. Non-Intervention: The United States also warned European powers against any attempts to interfere with the newly independent countries in the Western Hemisphere. It stated that any such interference would be considered as a hostile act towards the United States.

The purpose of the Monroe Doctrine was to establish the United States as the dominant power in the Western Hemisphere and protect the sovereignty of newly independent countries from European influence or re-colonization. While the doctrine did not have any immediate enforcement mechanisms, it set a precedent and served as a significant American foreign policy principle.

Therefore, European colonization and intervention in the Western Hemisphere were held in check by the Monroe Doctrine.
