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.
Czechoslovak Socialist Republic
In late-1989, the country became a democratic country again through the Velvet Revolution. In 1992, the federal parliament decided to split the country into the Czech Republic and Slovakia, as of 1 January 1993.
