The relationship between religion and multiculturalism is complex, depending on definitions of the key concepts and the societal contexts in which it occurs. Unlike Western Europe and the United Kingdom, where discussions of multiculturalism usually involve religion, such discussions in the United States are more likely to focus on race, ethnicity, and immigration. Nonetheless, issues of religious diversity, pluralism, and multiculturalism are deeply intertwined in U.S. history, culture, and legal arrangements. From the protections for religious freedom in the U.S. Constitution to the current conservative politics that emphasize the nation's Protestant heritage, how to accommodate religious diversity in the polity and civil society is an ongoing, evolving, but contentious, process.
