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.

In January 1917, the Watch Tower Society's legal representative, Joseph Franklin Rutherford, was elected as its next president. His election was disputed, and members of the Board of Directors accused him of acting in an autocratic and secretive manner. The divisions between his supporters and opponents triggered a major turnover of members over the next decade. In June 1917, he released "The Finished Mystery" as a seventh volume of Russell's "Studies in the Scriptures" series. The book, published as the posthumous work of Russell, was a compilation of his commentaries on the Bible books of Ezekiel and Revelation, plus numerous additions by Bible Students Clayton Woodworth and George Fisher. It strongly criticized Catholic and Protestant clergy and Christian involvement in the Great War. As a result, Watch Tower Society directors were jailed for sedition under the "Espionage Act" in 1918 and members were subjected to mob violence; the directors were released in March 1919 and charges against them were dropped in 1920.
