From which country did the United States purchase the Louisiana Territory?

The United States purchased the Louisiana Territory from France in 1803 as part of the Louisiana Purchase, a significant event in American history. This acquisition was crucial as it doubled the size of the United States at that time, providing vast amounts of land for westward expansion. The transaction was motivated by various factors, including the desire for control over the Mississippi River, which was vital for trade and transportation. France, under Napoleon Bonaparte, had regained control of the territory from Spain before the sale, making it available for purchase. This bold move by President Thomas Jefferson reflected a commitment to territorial growth and the vision of an expanding nation.
