In late 1999, Russia's Premier, Vladimir Putin, ordered military, police and security forces to enter the breakaway region of Chechnya.
By early 2000, these forces occupied most of the region.
High levels of fighting
continued for several more years and resulted in thousands of Russian and Chechen casualties and hundreds of thousands of displaced persons.
In 2005, Chechen rebel leader, Abdul-Halim Sadulayev, decreed the formation of a Caucasus Front against Russia, among Islamic believers in the North Caucasus, in an attempt to widen Chechnya's conflict with Russia.
After his death, his successor, Dokka Umarov, declared continuing jihad to establish an Islamic fundamentalist Caucasus Emirate in the North Caucasus and beyond.
Russia's pacification policy in Chechnya has involved setting up a pro-Moscow regional government and transferring more local security duties to this government.

An important factor in Russia's apparent success in Chechnya has been reliance on pro-Moscow Chechen clans affiliated with regional President Ramzan Kadyrov.
Terrorist attacks in the North Caucasus appeared to increase substantially in 2007–2010.
In the summer of 2009, more than 442 persons died in North Caucasus violence in just four months as compared to only 150 deaths reported in the entire year of 2008.
In the whole year 2009, according to the official figures by the Russian government, 235 Interior Ministry personnel (Defense Ministry and the FSB losses not included) were killed and 686 injured, while more than 541 alleged fighters and their supporters were killed and over 600 detained.
The rate of increase of terrorist incidents lessened in 2010, as compared to 2008–2009, however the rate of civilian casualties substantially increased throughout the North Caucasus in 2010 and a rising number of terrorist incidents took place outside of Chechnya.

In the period from 2010 to 2014, the number of casualties in the North Caucasus insurgency declined each year, with the overall death toll falling by more than half.
Reasons suggested for the decline include the deaths of high-ranking insurgency commanders, the increased targeting by security forces of the support infrastructure relied on by the insurgents, and an exodus of insurgents to other conflict zones.
A special investigation by Reuters claimed that in the lead-up to the 2014 Sochi Olympics, Russian security services had allowed and encouraged militants to leave Russia to fight in the Syrian Civil War, in order to reduce the risk of domestic attacks.
