Greenberry George Rupert (1847-1922), generally known as G. G. Rupert, was an American Adventist pastor and writer associated with British Israelism and Dispensationalism. He published a number of books which attempted to interpret history from a biblical literalist and millenarian perspective. Rupert's theories were a seminal influence on the 20th-century evangelist Herbert W. Armstrong. His religious ideology was linked to a theory that the Last Days would see a power struggle between the "Orient" and the "Occident", a view that helped to fuel the Yellow Peril panic.
