Signing of the Eden Treaty

Mercantilist Context. Prior to 1786, Britain and France adhered to stringent mercantilist policies that aimed to negate foreign imports and protect domestic industries. These high tariffs and rivalries created tense diplomatic relationships. However, economic leaders like Adam Smith and the Physiocrats promoted liberal trade, and both nations faced urgent economic pressures that necessitated a remedy through negotiation.

Negotiation Process. Following failed earlier attempts to align tariff standards, William Pitt appointed William Eden as lead negotiator in late 1785. Eden worked immediately with his French counterpart, Joseph Matthias Gérard de Rayneval, to hammer out an agreement. The British delegation's obstinacy resulted in terms that were almost wholly beneficial to Britain, while the French accepted concessions to secure revenue and market access.

Treaty Terms. The treaty, agreed upon on 26 September 1786, established a system to reduce tariffs on goods from either country. Specifically, French wines were to pay no more than Portuguese wines in Britain, and duties on linens were capped relative to Dutch and Flemish standards. This effectively ended the brief economic war between the two nations, though the unequal protection weakened the French economy.

Collapse and Legacy. The treaty lasted only five and a half years. It collapsed in 1793 when the National Convention claimed the Aliens Act breached its terms, and the outbreak of war ended any chance of compromise. Despite its short duration, the Eden Treaty is significant in economic history as it marked the end of an important phase of commercial relations between England and France.
