Throughout Africa there are groups that split off from the Watchtower Society dating back to the late 1800's and which are called part of the Watchtower Movement, often confused with the modern Watchtower Society of Jehovah's Witnesses.
Perhaps the largest and most successful is the God's Kingdom Service group headquartered in Nigeria in West Africa, but many splinter groups are also found in East Africa. Most preach God, named Jehovah, wants earth to become paradise which the meek will inherit.
But many allow local views and some Old Testament examples of polygamy to hold sway, so that men can marry more than one woman. Also women are not given as much freedom as with Jehovah's Witnesses, in most cases.
Most Watchtower Movement groups permit some political freedom. A few have been highly political and some were also active in killing British and other colonial troops during national wars for independence in the 1900's.
