The Jehovah's Witnesses were founded in the 1870s by Charles Russell and formed their headquarters in 1881. They believe that Jesus' kingdom was established in heaven in 1914 and that the world will soon end, bringing a 1000-year reign of the righteous on earth. They reject celebrations like Christmas and birthdays, believe only 144,000 go to heaven with the rest living on paradise earth, and prioritize preaching over higher education. They face societal opposition due to their unorthodox beliefs but continue door-to-door evangelizing worldwide.
