Group conflict

Group conflict, or hostilities between different groups, is a feature common to all forms of social organization (e.g., sports teams, ethnic groups, nations, religions, gangs). Although group conflict is one of the most complex phenomena studied by social scientists, the history of the human race evidences a series of group-level conflicts that have gained notoriety over the years. For example, from 1820 to 1945, it has been estimated that at least 59 million persons were killed during conflicts between groups of one type or another. Literature suggests that the number of fatalities nearly doubled between the years 1914 to 1964 as a result of further group conflict.
