the major and prime objective was to: the acquisition increased the size of the United States, strengthened it strategically and materially , gave a major drive for westward growth, and established the federal Constitution's idea of implied powers.

In 1803, the United States purchased the land of Louisiana not mexico, from Napoleonic France as part of the Louisiana Purchase.

The Northwest Territory became a member of the United States as a result of the Treaty of Paris in 1783, not because of the acquisition of Louisiana.

In 1803, the United States purchased imperial rights to the western half of the Mississippi River basin from France as part of the Louisiana Purchase.

The Louisiana Purchase was a land purchase operation by the United States government from France for 27,267,622 dollars on April 30th, 1803. The land covered a wide area lying between the Mississippi River and the Rockies mountains.
