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.
Slovakia
After the Munich Agreement and its Vienna Award, Nazi Germany threatened to annex part of Slovakia and allow the remaining regions to be partitioned by Hungary or Poland unless independence was declared. Thus, Slovakia seceded from Czecho-Slovakia in March 1939 and allied itself, as demanded by Germany, with Hitler's coalition. Secession had created the first Slovak state in history. The government of the First Slovak Republic, led by Jozef Tiso and Vojtech Tuka, was strongly influenced by Germany and gradually became a puppet regime in many respects.
