Crusades
The term "crusade" used in modern historiography at first referred to the wars in the Holy Land beginning in 1095, but the range of events to which the term has been applied has been greatly extended, so that its use can create a misleading impression of coherence, particularly regarding the early Crusades. The term used for the campaign of the First Crusade was "iter" "journey" or "peregrinatio" "pilgrimage". The terminology of crusading remained largely indistinguishable from that of pilgrimage during the 12th century, reflecting the reality of the first century of crusading where not all armed pilgrims fought, and not all who fought had taken the cross. It was not until the late 12th to early 13th centuries that a more specific "language of crusading" emerged. Pope Innocent III used the term "negotium crucis" "affair of the cross" for the Eastern Mediterranean crusade, but was reluctant to apply crusading terminology to the Albigensian crusade. The "Song of the Albigensian Crusade" from about 1213 contains the first recorded vernacular use of the Occitan "crozada". This term was later adopted into French as "croisade" and in English as "crusade". The modern spelling "crusade" dates to c. 1760. Sinibaldo Fieschi (the future pope Innocent IV) used the terms "crux transmarina" for crusades in Outremer against Muslims and "crux cismarina" for crusades in Europe against other enemies of the church. Medieval Armenian term for Crusades — xacˇ‘e˘nkalk‘.
Siege of Acre (1291)
The 14th century saw some other crusades organized, but these enterprises differed in many ways from the 11th- and 12th-century expeditions which are properly called Crusades. The crusades of the 14th century aimed not at the recapture of Jerusalem and the Christian shrines of the Holy Land, but rather at checking the advance of the Ottoman Turks into Europe. While many of the crusaders in these 14th-century undertakings looked upon the defeat of the Ottomans as a preliminary to the ultimate recapture of the Holy Land, none of the later crusades attempted any direct attack upon Palestine or Syria.
