The twelfth century is seen as an era in which people, compared to the century before, lived comfortably but in this era both Second and Third Crusades were organized. In the Second Crusade the active agent was Clairvaux Monastery's Abbot Bernard. Bernard made a serious contribution to the formation of the campaign with the letters he wrote to many places and the sermons he gave. The expressions he uses for Muslims in his letters are examples of the Muslim sense of Christians of the era. In this study, Bernard's letters were examined in the original Latin text, and both the effects of the campaign and the Muslim sense of Christians of the era were then evaluated.
