Ruslan (Khamzat) Germanovich Gelayev was a prominent commander in the Chechen resistance movement against Russia, in which he played a significant, yet controversial, military and political role in the 1990s and early 2000s.

He was killed while leading a raid into the Russian Republic of Dagestan in 2004.
The 1999–2000 battle of Grozny was the siege and assault of the Chechen capital Grozny by Russian forces, lasting from late 1999 to early 2000. This siege and assault of the Chechen capital resulted in the widespread devastation of Grozny. In 2003, the United Nations designated Grozny as the most destroyed city on Earth due to the extensive damage it suffered. The battle had a devastating impact on the civilian population. It is estimated that between 5,000 and 8,000 civilians were killed during the siege, making it the bloodiest episode of the Second Chechen War.
The Kizlyar–Pervomayskoye hostage crisis, also known in Russia as the terrorist act in Kizlyar, 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 fighting subsided after the first 10 hours, with the Chechen Republic of Ichkeria decisively repelling the assault.
