French invasion initiates Peninsular War in Portugal, marked by intense conflict and resistance.

The French invasion of Portugal marked the beginning of the Peninsular War. Seeking to enforce the Continental System and control Portugal's ports, French forces crossed the border despite the nations having a long-standing alliance. The Portuguese royal family fled to Brazil under British protection, leaving the country vulnerable to occupation. The entry of French troops into Portugal triggered a series of events that would have a profound impact on the Iberian Peninsula. The subsequent guerrilla warfare, fought by Spanish and Portuguese forces alongside British allies, would become a defining feature of the conflict. The war would last for several years, draining French resources and manpower. This invasion reshaped the political landscape of Europe, as it drew British military involvement and strained the French Empire's control over the Iberian Peninsula. The Peninsular War also contributed to Napoleon's eventual downfall by tying down his forces and undermining his reputation. #PeninsularWar #FrenchInvasion #PortugalWar #NapoleonicWars
