of short-lived independent governments (Crimean People's Republic, Crimean Regional Government, Crimean SSR). They were followed by White Russian governments (General Command of the Armed Forces of South Russia and later South Russian Government). In October 1921, the Bolshevik Russian SFSR gained control of the peninsula and instituted the Crimean Autonomous Soviet Socialist Republic. Moscow joined the RSFSR with three other republics to form the Soviet Union the following year. After the Second World War and the subsequent deportation of all of the indigenous Crimean Tatars by the Soviet regime, the Crimean ASSR was stripped of its autonomy in 1946 and downgraded to the status of an oblast of the Russian SFSR. In 1954, the Crimean Oblast was transferred from the Russian SFSR to the Ukrainian SSR by decree of the Presidium of the Supreme Soviet of the Soviet Union to commemorate the 300th anniversary of Ukraine's union with Russia. In 1989, under Gorbachev's perestroika, the Supreme Soviet declared that the deportation of the Crimean Tatars under Stalin had been illegal and the mostly Muslim ethnic group was allowed to return to Crimea. In 1990, the Soviet of the Crimean Oblast proposed the restoration of the Crimean ASSR. The oblast conducted a referendum in 1991, which asked whether Crimea should be elevated into a signatory of the New Union Treaty (that is, become a union republic on its own). By that time, though, the dissolution of the Soviet Union was well underway. The Crimean ASSR was restored for less than a year as part of Ukrainian SSR before the restoration of Ukrainian independence. Newly independent Ukraine maintained Crimea's autonomous status, while the Supreme Council of Crimea affirmed the peninsula's "sovereignty" as a part of Ukraine. Ukrainian authorities limited Crimean autonomy in 1995.} During the 1990s, the dispute over control of the Black Sea Fleet and Crimean naval facilities were source of tensions between Russia and Ukraine. In 1992, Vladimir Lukin, then chairman of the Russian parliament's Committee on Foreign Affairs, suggested that in order to pressure Ukraine to give up its claim to the Black Sea Fleet, Russia should question Ukrainian control over Crimea. In 1998 the Partition Treaty divided the fleet and gave Russia a naval base in Sevastopol, and the Treaty of Friendship recognized the inviolability of existing borders. However, in 2003 Tuzla Island conflict issues over maritime border resurfaced. In September 2008, the Ukrainian Foreign Minister Volodymyr Ohryzko
