According to surveys conducted in the spring of 1990, 47% of Poles in Lithuania supported the pro-Soviet Communist party (in contrast to 8% support among ethnic Lithuanians), while 35% supported Lithuanian independence. The regional authorities in Vilnius and Šalčininkai region, under Polish leadership, with support from Soviet authorities, argued for the establishment of an autonomous region in South Eastern Lithuania, a request that was declined by the Lithuanian government and left lasting resentment among some residents. The same Polish regional leaders later voiced support for the Soviet coup attempt of 1991 in Moscow. The Government of Poland, however, never supported the autonomist tendencies of the Polish minority in Lithuania.
