Jehovah's Witnesses

Members of a religious denomination founded in the United States during the late 19th century in which active evangelism is practiced, the imminent approach of the millennium is preached, and war and organized government authority in matters of conscience are strongly opposed (from American Heritage Dictionary of the English Language, 4th ed). Jehovah's Witnesses generally refuse blood transfusions and other blood-based treatments based on religious belief.
