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.
Jehovah's Witnesses
Jehovah's Witnesses teach that Satan and his demons were cast down to earth from heaven after October 1, 1914, at which point the end times began. They believe that Satan is the ruler of the current world order, that human society is influenced and misled by Satan and his demons, and that they are a cause of human suffering. They also believe that human governments are controlled by Satan, but that he does not directly control each human ruler.
