Invasion of Portugal (1807)

Summary

French and Spanish forces invaded Portugal from 19–30 November 1807 during the Napoleonic Wars, sparking the Peninsular War. The Franco-Spanish invasion force was led by General Jean-Andoche Junot, while the Portuguese were under the nominal command of Prince Regent John, the future King John VI of Portugal. French and Spanish troops swiftly occupied the country in the face of little resistance due to the poor state of the Portuguese military.
