Although the role of religion in conflict has been gaining increasing attention in recent times, few cross-sectional studies have examined the extent to which internal conflict since World War II has been religious, and those that have done so are limited in either the type of conflict or time span they cover. Accordingly, this article uses the State Failure data set to assess whether the relative and absolute number of religious conflicts since World War II has increased, whether these con- flicts are more intense than other conflicts, and whether any particular religions participate in conflict more often than others. The findings show that while occurring less often than other types of conflicts, religious conflicts have increased between 1950 and 1996, and are more intense than nonreligious conflicts. Also, Christian groups dispropor- tionally participate in internal conflict, but most of those conflicts are with other Christian groups. This, along with other findings of the study, contradicts major elements of Samuel Huntington's ‰ÛÏclash of civilizations- theory.
