invasion of Portugal (1807)

The invasion of Portugal (19–30 November 1807) saw an Imperial French corps under Jean-Andoche Junot invade Portugal, which was headed by its Prince Regent John of Braganza. The military operation resulted in the almost bloodless occupation of Portugal because its government lacked the will to resist. However, the French 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.
