In 1803 the Louisiana was a territory of approximately 2 million km², bordering the north with the British possessions, the east with the Mississippi River and the south and west with the territories of Spain. It was populated by around 35,000 people (a third of them in New Orleans).
The United States was looking for ways to control navigation on the Mississippi River, which led to negotiations with the regime of Napoleon Bonaparte, then First French Consul.
For its part France was in a hurry to get rid of this colony that had obtained only two years ago, since the rich colony of Haiti had declared its independence from France, for which reason Louisiana had lost its strategic interest for the French.
Napoleon then preferred to sell the colony to the Americans and not run the risk of losing it to the English.
