Sociology of religion is the study of the beliefs, practices and organizational forms of religion using the tools and methods of the discipline of sociology. Modern academic sociology began with the analysis of religion in Emile Durkheim's 1897 study of suicide rates among Catholic and Protestant populations, a foundational work of social research which served to distinguish sociology from other disciplines, such as psychology. The works of Karl Marx and Max Weber emphasized the relationship between religion and the economic or social structure of society. Contemporary debates have centered on issues such as secularization, civil religion, and the cohesiveness of religion in the context of globalization and multiculturalism. The contemporary sociology of religion may also encompass the sociology of irreligion (for instance, in the analysis of secular humanist belief systems).
