Treaty of Finckenstein
The Treaty of Finckenstein, often spelled Finkenstein, was concluded between France and Persia (modern-day Iran) in Finckenstein Palace (East Prussia) on 4 May 1807 and formalised the Franco-Persian alliance. Napoleon I guaranteed the integrity of Persia, recognized part of Georgia and the other parts of Transcaucasia and a part of the North Caucasus (Dagestan) as Fath Ali Shah's possession, and was to make all possible efforts for restoring those territories to him. Napoleon also promised to furnish the Shah with arms, officers and workmen. France on its side required the Shah to declare war against the United Kingdom, to expel all British people from Persia, and to maintain an open way for if France wanted to attack British possessions in the far east. Despite the Treaty of Finckenstein, France failed to win a diplomatic war around Persia and none of the terms of the treaty were realized. On 12 March 1809, the United Kingdom signed a treaty with Persia forcing the French out of that country.
