I want to know the answer to the following question:
When did Charles Taze Russell form a group?
All the background I'm provided with is that "In June 1879 the two split over doctrinal differences, and in July, Russell began publishing the magazine Zion's Watch Tower and Herald of Christ's Presence, stating that its purpose was to demonstrate that the world was in "the last days," and that a new age of earthly and human restitution under the reign of Christ was imminent.". Is that enough to answer the question?
Answer: no
