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.

Religion in Medieval England
Participation in the Crusades was also seen as a form of pilgrimage, and the same Latin word, "peregrinatio", was sometimes applied to both activities. While English participation in the First Crusade between 1095–99 was limited, England played a prominent part in the Second, Third and Fifth Crusades over the next two centuries, with many crusaders leaving for the Levant during the intervening years. The idea of undertaking a pilgrimage to Jerusalem was not new in England, however, as the idea of religiously justified warfare went back to Anglo-Saxon times. Many of those who took up the Cross to go on a Crusade never actually left, often because the individual lacked sufficient funds to undertake the journey. Raising funds to travel typically involved crusaders selling or mortgaging their lands and possessions, which affected their families and, at times, considerably affected the economy as a whole.
