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 Portugal, Spain and 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.

Madrid is the capital and most populous municipality of Spain. It has almost 3.5 million inhabitants and a metropolitan area population of approximately 7 million. It is the second-largest city in the European Union (EU), second only to Berlin, Germany, and its metropolitan area is the second-largest in the EU. The municipality covers 604.3 km² (233.3 sq mi) geographical area. Madrid lies on the River Manzanares in the central part of the Iberian Peninsula at about 650 m (2,130 ft) above mean sea level. The capital city of both Spain and the surrounding autonomous community of Madrid, it is also the political, economic, and cultural centre of the country.

The Dos de Mayo or Second of May Uprising took place in Madrid, Spain, on 2–3 May 1808. The rebellion, mainly by civilians, with some isolated military action by junior officers, was against the occupation of the city by French troops, and was violently repressed by the French Imperial forces, with hundreds of public executions.

Francisco José de Goya y Lucientes was a Spanish romantic painter and printmaker. He is considered the most important Spanish artist of the late 18th and early 19th centuries. His paintings, drawings, and engravings reflected contemporary historical upheavals and influenced important 19th- and 20th-century painters. Goya is often referred to as the last of the Old Masters and the first of the moderns.
