Slovakia
The Slovak Republic and the Czech Republic went their separate ways after 1 January 1993, an event sometimes called the Velvet Divorce. Slovakia has remained a close partner with the Czech Republic. Both countries co-operate with Hungary and Poland in the Visegrád Group. Slovakia became a member of NATO on 29 March 2004 and of the European Union on 1 May 2004. On 1 January 2009, Slovakia adopted the Euro as its national currency.
Slovak Super Liga
Slovakia was part of Czechoslovakia (1918–1993). First Slovak championship Zväzové Majstrovstvá Slovenska was played between Slovak teams (1925–1933). Until 1935-36, no Slovak team played in the Czechoslovak (professional, state) league. During German occupation of Czechoslovakia Czech and Slovak clubs were competed in their own, separate competitions. The sole Slovak club in the league, ŠK Bratislava, was removed from the league and joined a new Slovak league, the Slovenská liga (1939–1945), in the newly independent Slovak Republic.
