Crusade of Barbastro
The crusade of Barbastro (also known as the siege of Barbastro or battle of Barbastro) was an international expedition, sanctioned by Pope Alexander II, to take the Spanish city of Barbastro, then part of the Hudid Emirate of Lārida. A large army composed of elements from all over Western Europe took part in the siege and conquest of the city (1064). The nature of the expedition, famously described by Ramón Menéndez Pidal as "a crusade before the crusades", is discussed in historiography, and the crusading element of the campaign is still a moot point.
