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.
Persecution of Jehovah's Witnesses in Nazi Germany
Jehovah's Witnesses were an outgrowth of the International Bible Students, who began missionary work in Europe in the 1890s. A German branch office of the Watch Tower Society opened in Elberfeld in 1902. By 1933, almost 20,000 Witnesses were counted as active door-to-door preachers, and their annual Memorial service was attracting almost 25,000 people. In Dresden, there were more Bible Students than in New York, where the Watch Tower Society was headquartered.
