Monroe Doctrine: In a State of the Union message, U.S. President James Monroe proclaims American neutrality in future European conflicts, and warns European powers not to interfere in the Americas.

The State of the Union Address (sometimes abbreviated to SOTU) is an annual message delivered by the president of the United States to a joint session of the United States Congress near the beginning of each calendar year on the current condition of the nation. The State of the Union Address generally includes reports on the nation's budget, economy, news, agenda, achievements and the president's priorities and legislative proposals.The address fulfills the requirement in Article II, Section 3, Clause 1 of the U.S. Constitution for the president to periodically "give to the Congress Information of the State of the Union, and recommend to their Consideration such measures as he shall judge necessary and expedient." During most of the country's first century, the president primarily submitted only a written report to Congress. After 1913, Woodrow Wilson, the 28th U.S. president, began the regular practice of delivering the address to Congress in person as a way to rally support for the president's agenda. With the advent of radio and television, the address is now broadcast live in all United States time zones on many networks.Starting 1981, Ronald Reagan, the 40th U.S. president, began the practice of newly inaugurated presidents delivering an address to Congress in the first year of their term, but not designating that speech an official "State of the Union".

The Monroe Doctrine was a United States foreign policy position that opposed European colonialism in the Western Hemisphere. It held that any intervention in the political affairs of the Americas by foreign powers was a potentially hostile act against the U.S. The doctrine was central to U.S. foreign policy for much of the 19th and early 20th centuries.President James Monroe first articulated the doctrine on December 2, 1823, during his seventh annual State of the Union Address to Congress (though it would not be named after him until 1850). At the time, nearly all Spanish colonies in the Americas had either achieved or were close to independence. Monroe asserted that the New World and the Old World were to remain distinctly separate spheres of influence, and thus further efforts by European powers to control or influence sovereign states in the region would be viewed as a threat to U.S. security. In turn, the U.S. would recognize and not interfere with existing European colonies nor meddle in the internal affairs of European countries.

By the end of the 19th century, Monroe's declaration was seen as a defining moment in the foreign policy of the United States and one of its longest-standing tenets. The intent and effect of the doctrine persisted for over a century, with only small variations, and would be invoked by many U.S. statesmen and several U.S. presidents, including Ulysses S. Grant, Theodore Roosevelt, John F. Kennedy, and Ronald Reagan.

After 1898, the Monroe Doctrine was reinterpreted by Latin American lawyers and intellectuals as promoting multilateralism and non-intervention. In 1933, under President Franklin D. Roosevelt, the U.S. affirmed this new interpretation, namely through co-founding the Organization of American States. Into the 21st century, the doctrine continues to be variably denounced, reinstated, or reinterpreted.
