Dissolution of Czechoslovakia
On 1 January 2009 Slovakia adopted the Euro as its currency with the exchange rate of 30.126 SK/€, and the €2 commemorative coin for 2009, Slovakia's first, featured the 20th anniversary of the Velvet Revolution in remembrance of the common struggle of the Czechoslovak people for democracy. By a quirk of fate, the welcoming speech on the behalf of the European Union on the occasion of Slovakia's entry to the Eurozone was delivered by Mirek Topolánek, the prime minister of the then-EU presiding country, the Czech Republic, naturally in his native language while other guest speakers used English. The Czech Republic continues to use the Czech koruna, or crown.
European Exchange Rate Mechanism
As of 2016, only the Danish krone participates in ERM II. The currencies of Sweden (the Swedish krona), the three largest countries which joined the European Union on 1 May 2004 (the Polish złoty, the Czech koruna, and the Hungarian forint), the two countries which joined on 1 January 2007 (the Bulgarian lev, and the Romanian leu) as well Croatia, which joined the EU on 1 July 2013 (the Croatian kuna), are required to join in accordance with the terms of the applicable treaties of accession.
