Why does religion sometimes increase support for democracy and sometimes do just the opposite? In this book, political scientist Michael Hoffman presents a theory of religion, group interest, and democracy. Focusing on communal religion, he demonstrates that the effect of communal prayer on support for democracy depends on the interests of the religious group in question. For members of groups who would benefit from democracy, communal prayer increases support for democratic institutions; for citizens whose groups would lose privileges in the event of democratic reforms, the opposite effect is present. Using a variety of data sources, Hoffman illustrates these claims in multiple contexts. He places particular emphasis on his study of Lebanon and Iraq, two countries in which sectarian divisions have played a major role in political development, by utilising both existing and original surveys.
