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.
History of Slovakia
The victorious Powers restored Czechoslovakia in 1945 in the wake of World War II, albeit without the province of Ruthenia, which Prague ceded to the Soviet Union. The Beneš decrees, adopted as a result of the events of the war, led to disenfranchisement and persecution of the Hungarian minority in southern Slovakia. (The affected Hungarians regained Czechoslovak citizenship in 1948.)
