Treaty of Fontainebleau (October 1807)

Under the treaty, the House of Braganza was to be driven from the Kingdom of Portugal with the country subsequently divided into three regions, the north and south to be ruled by Duke of Parma and Spanish minister Manuel Godoy respectively, while the provinces of Beira, Tras-os-Montes and Portuguese Estremadura would remain in abeyance until a later peace.

[1] Negotiated and agreed between Don Eugenio Izquierdo [es], plenipotentiary of Charles IV, and Marshal Géraud Duroc as the representative of Napoleon,[2][3] the accord contained 14 articles along with supplementary provisions relating to troop allocations for the planned invasion of Portugal.

Aside from his desire to occupy Portugal, his real purpose may have been to surreptitiously introduce a large French force into Spain in order to facilitate its subsequent takeover.

[4] After his attempt to invade Great Britain in 1806 failed,[5] Napoleon decreed a Continental Blockade, which prohibited trade of British products throughout the European continent.

[2] Under this section the province of Alentejo, along with the Kingdom of the Algarves were to be given to Manuel Godoy, Prime Minister of Spain and confidant of Charles IV's wife, Maria Luisa of Parma.

[A][4] Control of the provinces of Beira, Tras-os-Montes and Portuguese Estremadura would remain in abeyance until a general peace occurred, whereupon they would be disposed of according to a further agreement between the treaty parties.
