The Soviet coup d'état attempt on 19 August 1991 became the spark for the so-called Chechen revolution. On 21 August the NCChP called for the overthrow of the Supreme Soviet of the Chechen-Ingush Republic. On September 11, 1991 Gennady Burbulis and Mikhail Poltoranin were dispatched from Moscow by the federal authorities to try restore order. On September 14, Ruslan Khasbulatov, a Chechen elected in 1990 to the Supreme Soviet of Russia from Grozny and its acting chairman after June 1991, arrived in Grozny. On September 15, at a special session of the Chechen-Ingush Supreme Soviet, he persuaded the deputies to remove Zavgaev and to disband, in anticipation of new parliamentary elections, which were set for November 17. The political struggle between the radical nationalist forces, grouped around Dudaev and pushing for independence, and the conservative nomenklatura, trying to preserve the status quo, continued.
