Outbreak of the Peninsular War: The people of Madrid rise up in rebellion against French occupation. Francisco de Goya later memorializes this event in his painting The Second of May 1808.

The Peninsular War (1808–1814) was fought in the Iberian Peninsula by the Iberian nations Spain and Portugal, along with the United Kingdom, against the invading and occupying forces of the First French Empire during the Napoleonic Wars. In Spain, it is considered to overlap with the Spanish War of Independence. It overlapped with the War of the Fifth Coalition (1809) and the War of the Sixth Coalition (1812–1814).
