Controversy and criticism

Of the many new religious movements to appear during the 20th century, the Church of Scientology has, from its inception, been one of the most controversial. The organization has come into conflict with the governments and police forces of several countries (including the United States, the United Kingdom, and Germany) numerous times over the years, though supporters note that many major world religions have found themselves in conflict with civil government in their early years.
