France under Napoleon sought to expand influence in the Middle East and pressure Britain, while Persia under Fath Ali Shah needed military support against Russian expansion into Georgia, Transcaucasia, and Dagestan. Both powers saw strategic benefit in a formal alliance directed against their respective adversaries.
On 4 May 1807 at Finckenstein Palace, France and Persia signed a treaty in which Napoleon guaranteed Persian territorial integrity and promised arms, officers, and military assistance. In return, Persia agreed to declare war on Britain, expel British nationals, and allow France passage toward British possessions in the Far East.
France concluded the Treaties of Tilsit with Russia just two months later, effectively abandoning Persia and rendering the Finckenstein commitments void. None of the treaty's provisions were fully implemented. By March 1809, Britain negotiated its own treaty with Persia, forcing French influence out of the country entirely.
Political Outcome
Treaty signed but never implemented; France abandoned Persia upon concluding peace with Russia at Tilsit, and Britain subsequently displaced French influence in Persia by 1809.
Persia aligned with France against Britain and Russia; France sought influence in the Middle East
France withdrew from Persian affairs; Britain gained dominant diplomatic position in Persia by 1809
