Jehovah's Witnesses - Originally a American Fundamentalist Christian denomination organized by Charles Taze Russell during the 1870s, it has since spread worldwide. Members are expected to volunteer significant amounts of time to proselytize in their communities by going door-to-door. Their practice of pacifism resulted in clashes with the American and Canadian government during World War II. This resulted in many court decisions that made major contributions to the definition of religious freedom in the two countries.

Jehovah's Witnesses are members of an international religious organization of the same name. They believe that they are the restoration of first-century Christianity. The preaching, evangelistic and publishing activities of Jehovah's Witnesses are extensive, and congregations have been established in most parts of the world. (wikipedia)
