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 Republic (1939–1945)
The First Slovak Republic ceased to exist "de facto" on 4 April 1945 when the Red Army captured Bratislava and occupied all of Slovakia. "De jure" it ceased to exist when the exiled Slovak government capitulated to General Walton Walker leading the XX Corps of the 3rd US Army on 8 May 1945 in the Austrian town of Kremsmünster. In summer 1945, the captured former president and members of former government were handed over to Czechoslovak authorities.
