Estonian kroon Estonian kroon The kroon (sign: kr; code: EEK) was the official currency of Estonia for two periods in history: 1928–1940 and 1992–2011. Between 1 January and 14 January 2011, the kroon circulated together with the euro, after which the euro became the sole legal tender in Estonia. The kroon was subdivided into 100 cents ("senti"; singular "sent"). The word "kroon" (, “crown”) is related to that of the Nordic currencies (such as the Swedish krona and the Danish and Norwegian krone) and derived from the Latin word "corona" ("crown"). The kroon succeeded the mark in 1928 and was in use
Economic and Monetary Union of the European Union various previous proposals, an expert group chaired by Luxembourg's Prime Minister and Finance Minister, Pierre Werner, presented in October 1970 the first commonly agreed blueprint to create an economic and monetary union in three stages (Werner plan). The project experienced serious setbacks from the crises arising from the non-convertibility of the US dollar into gold in August 1971 (i.e., the collapse of the Bretton Woods System) and from rising oil prices in 1972. An attempt to limit the fluctations of European currencies, using a "snake in the tunnel", failed. The debate on EMU was fully re-launched at the Hannover Summit
