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.
History of religion in the United States
Jehovah's Witnesses comprise a fast-growing denomination that has kept itself separate from other Christian denominations. It began in 1872 with Charles Taze Russell, but experienced a major schism in 1917 as Joseph Franklin Rutherford began his presidency. Rutherford gave new direction to the movement and renamed the movement "Jehovah's witnesses" in 1931. The period from 1925 to 1933 saw many significant changes in doctrine. Attendance at their yearly Memorial dropped from a high of 90,434 in 1925 to 63,146 in 1935. Since 1950 growth has been very rapid.
