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.
Operation North
There were almost no Jehovah's Witnesses in the Soviet Union until its annexation of the Baltic States, Western Belarus, Western Ukraine, Bessarabia, and Northern Bukovina; most of them were located in the Moldavian SSR and Ukrainian SSR. Jehovah's Witnesses came into the conflict with the Soviet power, primarily because of their refusal to join the military. Their teachings were soon regarded as anti-Soviet. Members of religious groups, including Jehovah's Witnesses, qualified as religious elements considered a potential danger for the communist regime. In November 1950, Viktor Abakumov reported an idea to Stalin about their deportation, and Stalin suggested to plan this for March–April 1951.
