COLUMBIAN CENTINEL, Boston, July 23, 1803 

* The Louisiana Purchase Treaty
* Signed by U.S. & France ministers

Page 2 has: "By the President of the United States...A PROCLAMATION" calling for a special session of Congress, signed in type: Th. Jefferson.
This is followed by a very historic report headed: "Louisiana - Official" which mentions in part: "Dispatches from the American ministers at Paris...contain the treaty, signed on April 30th which conveys Louisiana to the United States...The terms are, 1st. 11,250,000 dollars to be paid to France in six per cent stock. 2nd An assumption of the debts due & capture provided for under the convention of Sept. 30th, 1800..." with more.
Additionally the front page has an editorial concerning the Purchase headed: "Louisiana".
Four pages, never-trimmed margins, minor margin wear, good condition.

Background: The events detailed in this issue of the Columbian Centinel mark a pivotal turning point that fundamentally redefined the geopolitical, economic, and constitutional trajectory of the United States. By securing the Louisiana Purchase, the Jefferson administration instantly doubled the nation's landmass, removing a powerful French military presence from the western border and guaranteeing permanent American access to the vital Mississippi River and the strategic port of New Orleans, which became the economic lifeblood for western commerce. However, the official proclamation and treaty details also ignited a profound constitutional crisis and a fierce partisan battle; because the Constitution did not explicitly grant the federal government the power to acquire foreign territory, Jefferson—a strict constructionist—had to adopt a broad interpretation of executive power to push the deal through. This monumental acquisition not only laid the groundwork for rapid westward expansion and the concept of Manifest Destiny, but it also intensely exacerbated sectional tensions over the future expansion of slavery into the new territories, ultimately sowing the seeds that would lead to the American Civil War.
