Jehovah's Witnesses is a nontrinitarian, millenarian, and restorationist Christian denomination, stemming from the Bible Student movement founded by Charles Taze Russell in the nineteenth century. Russell 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 the group from other Bible Student groups and symbolize a break with the legacy of Russell's traditions. In 2024, Jehovah's Witnesses reported a peak membership of approximately 9 million worldwide.
Jehovah's Witnesses are known for their evangelism, 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 unscriptural doctrines. Jehovah's Witnesses 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 to all of humanity's problems. 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.
