In what year was the movement officially named Jehovah's Witnesses?

The movement was officially named Jehovah's Witnesses in 1931 during a convention held in Columbus, Ohio. This naming was a crucial step for the group, as it aimed to create a distinct identity apart from traditional Christian denominations and to emphasize their beliefs in using God's name, Jehovah. Prior to this name change, they were known as the Bible Students or International Bible Students Association. By adopting the name Jehovah's Witnesses, the group sought to reflect their understanding of their role as witnesses to God's Kingdom and to unify their members under a common identity, which was important for their organizational structure and outreach efforts. The choice of the name also marked a significant point in their development as a religious movement, emphasizing their distinct theological interpretations and practices.
