MASSACHUSETTS SPY & WORCESTER ADVERTISER, Dec.  10, 1823  

* James - Monroe Doctrine
* State of the Union Address

Pages 2 and 3 contain the "MESSAGE" being James Monroe's annual address to Congress.
Part of his message contains the historic language warning European powers not to get involved in any affairs in the western hemisphere. Notable within this text, near the beginning is "...as a principle in which the rights and interests of the United States are involved, that the American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers...”.
This directive became known as the Monroe Doctrine and served as the cornerstone for American foreign policy for most of the 19th century. The message, takes over 5 columns, is signed in type: James Monroe.
Four pages, very nice condition.

Background: This museum-grade 1823 original of the Massachusetts Spy captures the lightning-strike moment American foreign policy changed forever: the birth of the Monroe Doctrine. Spanning five massive columns and bearing the printed signature of James Monroe, this isn't just a newspaper—it is the primary source document of a bold "line in the sand" drawn against the empires of the Old World. In this very text, the United States pivoted from a post-colonial fledgling to a dominant global power, explicitly warning European monarchs that the American continents were "henceforth not to be considered as subjects for future colonization." To hold this four-page folio in such remarkable condition is to hold the literal blueprint of 19th-century history, marking the definitive end of the Age of Exploration and the defiant rise of American hegemony.
