Historical background Before the
Soviet occupation of Bessarabia and Northern Bukovina and the creation of the
Moldavian SSR in 1940, the
Bessarabian part of
Moldova, i.e. the part situated to the west of the river
Dniester (Nistru), was part of Romania (1918–1940). The
Molotov–Ribbentrop Pact between the
Soviet Union and
Nazi Germany, which led to the events of 1940, was later denounced by present-day Moldova, which declared it "null and void" in its
Declaration of Independence in 1991. However, after the breakup of the Soviet Union, the territorial changes resulting from it have remained in place. Before the creation of the
Moldavian SSR, today's Transnistria was part of the
Ukrainian SSR as an autonomous republic called the
Moldavian Autonomous Soviet Socialist Republic, with
Tiraspol as its capital (1924–1940). It represents slightly more than one tenth of Moldova's territory.
Political background Under Soviet rule, the Moldavian SSR became subject to a
Russification policy, including isolation from the Romanian cultural sphere and the imposition of the Cyrillic alphabet for the Romanian language. During the last years of the 1980s, the political landscape of the
Soviet Union was changing due to
Mikhail Gorbachev's policies of
perestroika and
glasnost, which allowed political pluralism at the regional (republican) level. In the Moldavian SSR, as in many other parts of the Soviet Union, national movements became the leading political force. As these movements exhibited increasingly nationalist sentiments and expressed intent to leave the USSR in favor of uniting with Romania, they encountered growing opposition from among the primarily Russian-speaking ethnic minorities living in the republic. This opposition to the new trends and potential future policies was manifested in a more visible way in Transnistria, where, unlike the rest of the MSSR, ethnic
Moldovans (39.9%) were outnumbered by the combined figure of Russians and Ukrainians (53.8%) as per the
1989 census in Transnistria, largely due to higher immigration during the Soviet era. While some believe that the combination of a distinct history (especially 1918–1940) and a fear of discrimination by Moldovans, gave rise to separatist sentiments, others believe that ethnic tensions alone fail to account for the dynamics of the conflict. According to John Mackinlay and Peter Cross, who conducted a study based on casualty reports, significant numbers of both Transnistrians and Moldovans fought together on both sides of the conflict. They suggest that the conflict is more political in nature. On 31 August 1989, the Supreme Soviet of the Moldavian SSR enacted two laws. One of them made
Moldovan the official language, in lieu of
Russian, the
de facto official language of the Soviet Union. It also mentioned a
linguistic Moldo–Romanian identity. The second law stipulated the return to the
Latin Romanian alphabet.
Moldovan language is the term used in the former Soviet Union for a virtually identical dialect of the
Romanian language during 1940–1989. On 27 April 1990, the Supreme Soviet of the Moldavian SSR adopted the traditional tricolour (blue, yellow and red) flag with the Moldavian coat of arms. Later that year, the words
Soviet and
Socialist were dropped and the name of the country was changed to "
Republic of Moldova". In 1991, the national anthem was changed to
Deșteaptă-te, române!, the national anthem of Romania since 1990. These events, including the
end of the
Ceaușescu regime in neighboring Romania in December 1989 and the partial opening of the border between Romania and Moldova on 6 May 1990, led many in
Transnistria and Moldova to believe that a union between Moldova and Romania was inevitable. This possibility caused fears among the Russian-speaking population that they would be excluded from most aspects of public life. From September 1989, there were strong scenes of protests in the region against the central government's ethnic policies. The protests developed into the formation of secessionist movements in
Gagauzia and Transnistria, which initially sought autonomy within the Moldavian SSR, in order to retain Russian and
Gagauz as official languages. As the nationalist-dominated Moldavian Supreme Soviet outlawed these initiatives, the
Gagauz Republic and Transnistria declared themselves as separate from Moldova and announced their application to be reattached to the Soviet Union as independent federal republics. Local women stormed the Court and Prosecutor's Office and stayed there for several hours. A police detachment was then dispatched to clear a roadblock placed by the city residents on the bridge over the river
Dniester that effectively cut the city off from the central government. After being prevented from clearing the roadblock, policemen opened fire, with three residents of Dubăsari being killed and 13 wounded, resulting in the first casualties of the conflict. The PMR interpreted this as meaning that the 1940-merger of the two sides of the Dniester river was dissolved. Moldova, however, did not agree, as large portions of the territory occupied in 1940 by the USSR remain in Ukraine, and almost immediately took steps to assert its sovereignty over the full territory of the former MSSR. At that time, the Republic of Moldova did not have its
own army, and the first attempts to create one took place in early 1992 in response to the escalating conflict. The newly independent Moldovan parliament asked the government of the USSR "to begin negotiations with the Moldovan government in order to put an end to the illegal occupation of the Republic of Moldova and withdraw Soviet troops from Moldovan territory". When, on 29 August 1991, Transnistria's independence leader
Igor Smirnov and three other deputies arrived in
Kyiv, the capital of Ukraine, to meet Ukrainian leader
Leonid Kravchuk, Smirnov and Andrei Cheban were arrested by Moldova's police and immediately transported to a prison in Moldova. In protest, the women's strike committee headed by Galina Andreeva blocked the Moscow–Chișinău railway line at a waypoint between
Bender (Tighina) and
Tiraspol, until the men were freed. In late 1991, policemen in
Tiraspol and
Rîbnița swore allegiance to the PMR. ==Military strength==
