The crusades &; a broad term encompassing a disparate series of military expeditions, with the avowed intent of preserving/expanding Christianity and the heterodoxy of the Roman Church &; were a quintessential phenomenon of moral and religious life in medieval Europe. Traditionally, Ireland&;s connection with the crusades has been seen to be slight. In recent years, however, new research has begun to replace this view with a more nuanced picture. This is an interdisciplinary volume of essays from leading scholars working in this field, which re-examines Ireland&;s connection to the crusading movement in its many forms.
