In 1803, President Thomas Jefferson negotiated the purchase of 820,000 square miles of land from Napoleon, including the modern states of Louisiana, Arkansas, Missouri and Colorado, among many others. At the stroke of a pen, the nation almost doubled in size. But the purchase of Louisiana was only the beginning. Immediately, the American government was forced to reckon with a series of difficult questions – not least about how to incorporate this enormous, multi-ethnic territory into the United States, and what to do about the Indigenous population who had inhabited the Territory for millennia.

But why did Napoleon agree to sell Louisiana in the first place? How did this territory, and its inhabitants, become part of the fledgling United States? And what impact did these monumental events have on the course of American history?

This is a Short History Of the Louisiana Purchase.
