Summarize.
Expressed to Congress on Decemeber 2nd, 1823, during President James Monroe's seventh annual message, the Monroe doctrine opens with reference to a discussion with the Russian Imperial Government and the Government of Great Britain about possible colonization of the northwestern coast of North America. He then states that although he values the friendship of both governments, it is in the best interests of the United States that American continents are to no longer be considered for colonization by any European powers.
With the recent events in Spain and Portugal, Monroe finds evidence that Europe is still unsettled. The policy of the United States in accordance with foreign affairs, is and will continue to be friendly neutrality, and not interference with any of it's internal government.
He finds that any attempt of the allied powers to extend their government to either of the American continents without the possible endangerment of the United States, and that those in South America would not adopt a European government of their own accord. Therefore, any such attempts would be considered an unfriendly act towards the United States that would not be met with indifference.
