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.

Czechoslovakia was dissolved on 31 Dec 1992 when the Czech Republic and Slovakia became separate
states. Stamps were issued soon afterwards with the inscription ČESKÁ REPUBLIKA.
