History of Jehovah's Witnesses
Jehovah's Witnesses originated as a branch of the Bible Student movement, which developed in the United States in the 1870s among followers of Christian Restorationist minister Charles Taze Russell. Bible Student missionaries were sent to England in 1881 and the first overseas branch was opened in London in 1900. The group took on the name International Bible Students Association and by 1914 it was also active in Canada, Germany, Australia and other countries. The movement split into several rival organizations after Russell's death in 1916, with one—led by Russell's successor, Joseph "Judge" Rutherford—retaining control of both his magazine, "The Watch Tower", and his legal and publishing corporation, the Watch Tower Bible and Tract Society of Pennsylvania.
Development of Jehovah's Witnesses doctrine
The main points of his doctrines on Bible chronology were:Former Governing Body member Raymond Franz and Sociology lecturer Andrew Holden have pointed out that doctrines—including those relating to sexual behaviour in marriage and the "superior authorities" of Romans 13:4—have sometimes been altered, only to revert to those held decades earlier. Holden, author of a major ethnographic study on Jehovah's Witnesses, commented: "It could be that many Witnesses have not yet been in the organisation long enough to realise that 'new lights' have a habit of growing dimmer, while old ones are switched back on!" In his study of the Witnesses and their history, Tony Wills has suggested that when third president Nathan H. Knorr altered major doctrines established by his predecessor, J. F. Rutherford, he was returning the Witnesses to many of Russell's teachings. He asked: "How can the Society harmonize this circular development with the claimed progressive development?"
