Chechen declaration of independence
Meanwhile, on 6 September 1991, militants of the All-National Congress of the Chechen People (NCChP) party, created by the former Soviet Air Force general Dzhokhar Dudayev, stormed a session of the Supreme Soviet of the Checheno-Ingush Autonomous Soviet Socialist Republic, with the aim of asserting independence. The storming caused the death of the head of Grozny's branch of the Communist Party of the Soviet Union Vitaliy Kutsenko, who was defenestrated or fell while trying to escape. This effectively dissolved the government of the Checheno-Ingush Autonomous Republic of the Soviet Union.[29][30][31]

Elections for the president and parliament of Chechnya were held on 27 October 1991. The day before, the Supreme Soviet of the Soviet Union published a notice in the local Chechen press that the elections were illegal. With a turnout of 72%, 90.1% voted for Dudayev.[32]

Dudayev won overwhelming popular support (as evidenced by the later presidential elections with high turnout and a clear Dudayev victory) to oust the interim administration supported by the central government. He became president and declared independence from the Soviet Union.

In November 1991, Yeltsin dispatched Internal Troops to Grozny, but they were forced to withdraw when Dudayev's forces surrounded them at the airport. After Chechnya made its initial declaration of sovereignty, the Checheno-Ingush Autonomous Republic split in two in June 1992 amidst the armed conflict between the Ingush and Ossetians. The newly created Republic of Ingushetia then joined the Russian Federation, while Chechnya declared full independence from Moscow in 1993 as the Chechen Republic of Ichkeria (ChRI).
