Answer: The great purge also known as the great terror was a brutal political campaign led by Soviet dictator Josef Stalin to illuminate dissenting members of the community party and anyone else he considered a threat. Although estimates vary most experts believe at least 750,000 people were executed during the great purge which took place between about 1936 and 1938. More than 1 million other people were sent to forced labor camps known as gulags. This ruthless and bloody operation caused rampant terror throughout the U.S.S.R and impacted the country for many years.
