Convention of 1800

The Convention terminated the 1778 agreements, confirmed the principle of 'free trade, free goods' between the two countries and ended the 1798–1800 Quasi-War, an undeclared naval war waged primarily in the Caribbean.

Despite popular enthusiasm for the French Revolution, there was little support for this in Congress; neutrality allowed Northern shipowners to earn huge profits evading the British blockade, and Southern plantation-owners feared the example set by France's abolition of slavery in 1794.

France accepted, on the basis of "benevolent neutrality"; this meant allowing French privateers access to US ports, and the right to sell captured British ships in American prize courts, but not vice versa.

American neutrality was essential for French plans for North America; under the secret Third Treaty of San Ildefonso of October 1800, Spain agreed to transfer Louisiana to France in return for territories in Italy.

[13] Talleyrand now had all the pieces in place to re-establish a French presence in North America; although the American commissioners did not have details of the Louisiana agreement, they were aware of the strength of his position and anxious to make a deal.

The Convention signed on 30 September contained 27 clauses, the majority of which related to commercial affairs; these protected each other's merchants from having their goods confiscated, and guaranteed both sides most favoured nation trading status.

[18] Negotiations between France and Britain to end the War of the Second Coalition resulted in the March 1802 Treaty of Amiens; although widely viewed as a short-lived truce, it gave Napoleon an opportunity to activate his plans for North America.

[19] This caused great concern in Congress, but by October 1802, it was clear the expedition was a catastrophic failure; its leader, General Charles Leclerc died of yellow fever, along with an estimated 22,000 of his men.

Without Saint-Domingue, Napoleon concluded Louisiana was irrelevant, and with France and Britain once again on the verge of hostilities, he decided to sell the territory to prevent it from being annexed by British forces garrisoned in nearby Canada.
