A Franco-Persian alliance or Franco-Iranian alliance was formed for a short period between the French Empire of Napoleon I and Fath Ali Shah of Iran against Russia and Great Britain between 1807 and 1809. The alliance was part of a plan to gather extra aid against Russia and by Persia's help, having another front on Russia's southern borders, namely the Caucasus region. The alliance unravelled when France finally allied with Russia and turned its focus to European campaigns.
