Napolean's authorization for the sale of the Louisiana Territory
As the United States Minister to France, Chancellor Livingston was tasked with negotiating with Emperor Napoleon for the sale of the Louisiana Territory. This undertaking lasted three years. Livingston's time in France influenced his taste in furniture, art, and design, and exposed him to new ventures in animal husbandry and technological innovation. The authorization for the sale of the territories marked a turning point in the relationship between the two nations, and Livingston famously remarked: “We have lived long, but this is the noblest work of our whole lives...From this day the United States take their place among the powers of the first rank."
