The Louisiana Purchase occurred during the term of the third President of the United States, Thomas Jefferson, (1757-1826). Before the purchase was finalized, the decision faced Federalist Party opposition; they argued that it was unconstitutional to acquire any territory.
With the Louisiana Purchase in 1803, the United States purchased approximately 828,000,000 square miles of territory from France, thereby doubling the size of the young republic.resident Thomas Jefferson commissioned the Corps of Discovery Expedition (1804-06), led by Meriwether Lewis and William Clark, to explore the territory acquired in the Louisiana Purchase, among other objectives. In 1801, Spain signed a secret treaty with France to return Louisiana Territory to France.
