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
Jehovah's Witnesses are organized hierarchically, and are led by the Governing Body of Jehovah's Witnesses from the Watch Tower Society's headquarters in Warwick, New York. The Governing Body, along with other "helpers", are organized into six committees responsible for various administrative functions within the global Witness community, including publication, assembly programs and evangelizing activity.
