The movement now recognised as Jehovah’s Witnesses emerged in the United States around 1870. It developed from the Bible Student and Adventist currents that were prevalent during the nineteenth century. The group was initially associated with the teachings of Charles Taze Russell, who played a foundational role in its early development.

Over the subsequent decades, the organisation underwent significant structural changes that helped define its modern identity. The movement became widely noted for its unique approach to biblical interpretation and its commitment to an extensive programme of evangelism.

Key characteristics of the movement include:

• The development of a global preaching network.
• A distinct approach to the interpretation of scripture.
• The evolution of the group from nineteenth-century Bible Student roots.
• A focus on organised, large-scale missionary work.

Through these efforts, the organisation established a presence that eventually extended far beyond its American origins. The movement continues to be identified by its specific theological perspectives and its persistent emphasis on public outreach.
