190 years ago, on December 2, 1823, US President James Monroe said that America would no longer put up with Europeans' intervention in the affairs of the new City.
Speaking with the annual message of Congress, he proclaimed that “American continents that have achieved freedom and independence and protect them should now not be considered as an object of future colonization from any European powers ... We must announce that we will have to consider their attempt to extend our system to any part of this hemisphere as a danger to our world and security ... Regarding the governments of countries, concerns of the governments of countries proclaiming and preserving their independence, and those whose independence, after a thorough study and based on the principles of justice, we admitted, we cannot consider any intervention of the European Power in order to inhibit these countries or establish any control over them otherwise than an unfriendly manifestation in relation to the United States. ”
The statement was caused by the war for the independence of the Spanish colonies in Latin America and the proclamation of the independence of the Brazilian Empire in 1822.
