Shamil Salmanovich Basayev, also known by his kunya "Abu Idris", was a North Caucasian guerilla leader who served as a senior military commander in the breakaway Chechen Republic of Ichkeria. He held the rank of brigadier general in the Armed Forces of Ichkeria, and was posthumously declared generalissimo. As a military commander in the separatist armed forces of Chechnya, one of his most notable battles was the separatist recapture of Grozny in 1996, which he personally planned and commanded together with Aslan Maskhadov. He also masterminded several of the worst terrorist attacks that occurred in Russia.

The Chechen Republic of Ichkeria, known simply as Ichkeria, and also known as Chechnya, was a de facto state that controlled most of the former Checheno-Ingush ASSR.
