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.
Organizational structure of Jehovah's Witnesses
From 1944, Watch Tower publications had made occasional references to a "governing body", identifying it with the board of directors of the Watch Tower Bible and Tract Society of Pennsylvania. In October 1971, four additional men joined the seven members of the Society's board of directors on what became known as a separate, expanded Governing Body. The Governing Body was then for the first time formally defined, indicating that it provided Jehovah's Witnesses with direction, guidance and regulation, although all doctrinal and publishing decisions continued to be made by, or were subject to, the approval of the Society's president. Organizational changes at the highest levels of the Watchtower Society in 1976 significantly increased the powers and authority of the Governing Body and reduced those of the Watch Tower Society president.
