It was long conflict, often armed, between the Russian government and various Chechen forces.
The First Chechen War, also known as the First Chechen Сampaign, First Russian-Chechen war, or officially (from Russian point of view) Armed conflict in the Chechen Republic and on bordering territories of the Russian Federation was a rebellion by the Chechen Republic of Ichkeria against the Russian Federation, fought from December 1994 to August 1996. After the initial campaign of 1994–1995, culminating in the devastating Battle of Grozny, Russian federal forces attempted to seize control of the mountainous area of Chechnya but were set back by Chechen guerrilla warfare and raids on the flatlands despite Russia's overwhelming advantages in firepower, manpower, weaponry, artillery, combat vehicles, airstrikes and air support. The resulting widespread demoralization of federal forces and the almost universal opposition of the Russian public to the conflict led Boris Yeltsin's government to declare a ceasefire with the Chechens in 1996 and sign a peace treaty a year later.
Second Chechen War, also known as the Second Chechen Сampaign or officially Counter-terrorist operations on territories of North Caucasian region, was an armed conflict on the territory of Chechnya and the border regions of the North Caucasus between the Russian Federation and the Chechen Republic of Ichkeria, also with militants of various Islamist groups, fought from August 1999 to April 2009.
