Ukrainian skaters competed for the Soviet Union for much of the 20th century. This ended after the December 1991 referendum, in which every oblast approved Ukraine's declaration of independence. In the second half of the 1991–92 season, Ukrainian skaters represented the Commonwealth of Independent States (at the 1992 Europeans and 1992 Worlds), and the Unified Team (at the 1992 Winter Olympics). By the start of the 1992–93 season, they were competing under the Ukrainian flag.
