"We have all heard numerous anecdotes about religious persecution around the world. Now, Brian Grim and Roger Finke provide the most comprehensive empirical overview of persecution available to date, detailing both when and where it is occurring. As an added bonus, their research explains why such persecution occurs. This book sets a new standard for research on religious freedom and should be in easy reach of any scholar, missionary or human rights activist interested in the just treatment of people of faith."
