July 4, 1803

Louisiana Purchase

First official U.S. public announcement of the Louisiana cession

The administration's newspaper announced the deal ten days before the treaty documents themselves reached Washington.

4 July 1803: the news arrives as a newspaper item

On 4 July 1803, Washington's National Intelligencer and Washington Advertiser published the first official public announcement that France had agreed to cede Louisiana to the United States.

It was not a presidential address or a proclamation. Samuel Harrison Smith's paper served as the administration's politically aligned organ, which is what made a newspaper item the official channel.

One day after Jefferson found out

The announcement followed by a single day the news reaching Jefferson that Robert R. Livingston and James Monroe had obtained all of Louisiana — not merely the objectives their instructions covered.

Livingston admitted to Jefferson that the negotiators had exceeded their powers. The stated price was $15 million, for an area conventionally estimated at 828,000 square miles.

Nothing actually changed hands

Publication made the agreement public; it neither ratified it nor transferred possession. The official treaty documents did not reach Washington until 14 July.

Possession came later still — New Orleans on 20 December 1803, Upper Louisiana in March 1804 — and what France ceded was its imperial claim, over land Indigenous nations continued to hold.
