The KizlyarPervomayskoye hostage crisis, also known in Russia as the terrorist act in Kizlyar (Russian: ), occurred in January 1996 during the First Chechen War. What began as a raid by Chechen separatist forces led by Salman Raduyev against a federal military airbase near Kizlyar, Dagestan, became a hostage crisis involving thousands of civilians, most of whom were quickly released. It culminated in a battle between the Chechens and Russian special forces in the village of Pervomayskoye, which was destroyed by Russian artillery fire. Although the Chechens escaped from the siege with some of their hostages, at least 26 hostages and more than 200 combatants on both sides died. One third of the homes in Pervomayskoye were destroyed.

The First Chechen War, also known as the First Chechen Campaign, or First Russian-Chechen war was a rebellion by the Chechen Republic of Ichkeria against the Russian Federation, fought from December 1994 to August 1996. The first war was preceded by the Russian Intervention in Ichkeria, in which Russia tried to covertly overthrow the Ichkerian government. 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 faced heavy resistance from Chechen guerrillas 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 finally a peace treaty in 1997.

The official figure for Russian military deaths was 5,732; most estimates put the number between 3,500 and 7,500, but some go as high as 14,000. Although there are no accurate figures for the number of Chechen forces killed, various estimates put the number between approximately 3,000 to 17,391 dead or missing. Various figures estimate the number of civilian deaths at between 30,000 and 100,000 killed and possibly over 200,000 injured, while more than 500,000 people were displaced by the conflict, which left cities and villages across the republic in ruins. The conflict led to a significant decrease of non-Chechen population due to violence and discrimination.
