The Peninsular War (1807β14) was a military conflict between Napoleon's empire and the allied powers of Spain, Britain and Portugal for control of the Iberian Peninsula during the Napoleonic Wars. The war started when French and Spanish armies invaded and occupied Portugal in 1807, and escalated in 1808 when France turned on Spain, its ally until then.
It was a grand conflict which involved hundreds of thousands of troops and the whole population of Spain in a generalized guerrilla warfare.
After the war no borders between France and Spain, between Spain and Portugal or between Spain and Britain (Gibraltar) were changed.
