The insurgency in the North Caucasus was a low-level armed conflict between Russia and militants associated with the Caucasus Emirate and, from June 2015, the Islamic State, in the North Caucasus. It followed the (Russian-proclaimed) official end of the decade-long Second Chechen War on 16 April 2009. It attracted volunteers from the MENA region, Western Europe, and Central Asia. The Russian legislation considers the Second Chechen War and the insurgency described in this article as the same "counter-terrorist operations on the territory of the North Caucasus region".
