1807 · 19th century

The Treaty of Fontainebleau (1807) was a secret agreement of 27 October 1807 between Napoleonic France and Spain to invade and partition Portugal. It allowed French troops to cross Spain and promised the Bourbon rulers of Etruria a new realm in northern Portugal in exchange for Tuscany, ending the Kingdom of Etruria. French armies used the treaty to occupy Spain itself, which led to the Peninsular War.
