Invasion of Portugal (1807)
The Invasion of Portugal (19–30 November 1807) saw an Imperial French corps under Jean-Andoche Junot and Spanish military troops invade the Kingdom of Portugal, which was headed by its Prince Regent João of Bragança (John of Braganza). The military operation resulted in the occupation of Portugal. The French and Spanish presence was challenged by the Portuguese people and by the United Kingdom in 1808. The invasion marked the start of the Peninsular War, part of the Napoleonic Wars.
