How many people died in the Bolshevik Revolution?

The Bolshevik Revolution itself, which occurred in October 1917, did not result in a large number of immediate deaths; estimates suggest several hundred to a few thousand casualties during the takeover. However, the subsequent Russian Civil War (1917-1922), which stemmed from the revolution, led to millions of deaths, with estimates ranging from 7 to 12 million due to combat, famine, and disease. Thus, while the revolution's direct death toll was relatively low, its broader consequences were devastating.
