"

Burgos has been the scene of many wars: with the Moors, the struggles between León and Navarre, and between Castile and Aragon. In the Peninsular War against Napoleonic France, the siege of Burgos (between 19 September to 21 October) was a scene of a withdrawal for Arthur Wellesley, 1st Duke of Wellington. Again in the 19th-century Carlist civil wars of the Spanish succession Burgos was the scene of a battle. During the Spanish Civil War, Burgos was the base of General Franco's rebel nationalist government.[citation needed]
