Jehovah's Witnesses is a nontrinitarian millenarian restorationist Christian denomination. As of 2022, the group reported a worldwide membership of approximately 8.5 million adherents involved in evangelism, with 19.7 million attending the annual Memorial of Christ's death. The denomination is directed by a group of elders in Warwick, New York, United States, known as the Governing Body of Jehovah's Witnesses, which establishes all doctrines based on its interpretations of the Bible. They believe that the destruction of the present world system at Armageddon is imminent, and the establishment of God's kingdom over earth is the only solution for all problems faced by humanity. The group emerged from the Bible Student movement founded in the late 1870s by Charles Taze Russell, who also co-founded Zion's Watch Tower Tract Society in 1881 to organize and print the movement's publications. A leadership dispute after Russell's death resulted in several groups breaking away, with Joseph Franklin Rutherford retaining control of the Watch Tower Society and its properties. Rutherford made significant organizational and doctrinal changes, including adoption of the name Jehovah's witnesses in 1931 to distinguish them from other Bible Student groups and symbolize a break with the legacy of Russell's traditions. Jehovah's Witnesses are known for their door-to-door preaching, distributing literature such as The Watchtower and Awake!, and for refusing military service and blood transfusions. They consider the use of God's name vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider to be unscriptural doctrines. They do not observe Christmas, Easter, birthdays or other holidays and customs they consider to have pagan origins incompatible with Christianity. They prefer to use their own Bible translation, the New World Translation of the Holy Scriptures, although their literature occasionally quotes and cites other Bible translations.
