This book provides insightful global perspectives on the emergent faith communities and new traditions and movements of the last two centuries. Readers will gain access to the information necessary to explore the significance, complexities, and challenges that modern religious traditions have faced throughout their history and that continue to impact society today. The work identifies the themes and issues that have often brought new religions into conflict with the larger societies of which they are a part. Coverage includes new religious groups that emerged in America, such as the Seventh-day Adventists, the Latter-day Saints, and the Jehovah's Witnesses; alternative communities around the globe that emerged from the major Western and Eastern traditions, such as Aum Shinrikyo and Al-Qaeda; and marginalized groups that came to a sudden end, such as the Peoples Temple, Heaven's Gate, and the Branch Davidians. The entries highlight thematic and broader issues that run across the individual religious traditions and will also help students analyze and assess the common difficulties faced by emergent religious communities.
