Describe how the united states came to acquire to louisiana territory from france. what intellectual problem did president jefferson face in trying to buy it

The United States of America purchased the vast territory of Louisiana from France in 1803 for the sum of $11,250,000, and took claims from American citizens against France for $3,750,000.  Lousiana had an extension of 838,000 square miles. or 2,144,520 square km. President Thomas Jefferson faced some negative perspectives: a French retrocession of the territory to Spain was possible, and there were grim prospects for a complicated negotiation.  Jefferson instructed his representative in Paris to try to block retrocession and attempt to buy at least New Orleans. But probably pressed hard by economic difficulties and the ghost of an imminent war with England, Napoleon Bonaparte agreed to sell the huge Lousiana to the US.
