Support for the Soviet Union remained high in Gagauzia, with a referendum in March 1991 returning an almost unanimous vote in favour of remaining part of the USSR. Many Gagauz supported the Moscow coup attempt in August 1991, and Gagauzia declared itself an independent republic on 19 August 1991. In September Transnistria declared its independence, thus further straining relations with the government of Moldova. But, when the Moldovan parliament voted on independence on 27 August 1991, six of the 12 Gagauz deputies in the Moldovan parliament voted in favour, while the other six abstained. The Moldovan government began to pay more attention to minority rights.
