Estimates of casualties in the Second Chechen War vary wildly, from 25,000 to 200,000 civilian dead plus 8,000 to 40,000 Russian military. (Separate figures for Chechen military fatalities from the second war only are not yet referenced in this article.)
Note: Some of these figures include the First Chechen War of 1994–1996. They usually don't include the death toll in Dagestan, Ingushetia, and other neighbouring regions of North Caucasus, where the violence spilled over from Chechnya.
