query: Who established the Jehovah's Witnesses?
passage: 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.[1] 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.
passage: Jehovah's Witnesses
Jehovah's Witnesses believe that the Bible condemns the mixing of religions, on the basis that there can only be one truth from God, and therefore reject interfaith and ecumenical movements. They believe that only Jehovah's Witnesses represent true Christianity, and that other religions fail to meet all the requirements set by God and will soon be destroyed. Jehovah's Witnesses are taught that it is vital to remain "separate from the world." The Witnesses' literature defines the "world" as "the mass of mankind apart from Jehovah's approved servants" and teach that it is morally contaminated and ruled by Satan. Witnesses are taught that association with "worldly" people presents a "danger" to their faith, and are instructed to minimize social contact with non-members to better maintain their own standards of morality. Attending university is discouraged and trade schools are suggested as an alternative.
