The Danish krone was introduced to Iceland in 1874. It replaced the earlier Danish currency, the
rigsdaler. Iceland began making its own currency in 1885. The Danish krone left Iceland after the collapse of the
Scandinavian Monetary Union. Iceland gained it's independence over Denmark in 1918, and the first coins were issued in 1922.
Iceland experienced hyperinflation in 1981. So the currency was revalued. This meant that the 100 old krónur (ISJ) became as valuable as 1 new króna (ISK). The new 500 krónur banknote was also put into circulation the same year. The largest banknote ever issued was a 10,000 krónur. This bill was made after the
2008–11 Icelandic financial crisis.
In 2009, the Althing voted to join the European Union. After the left-wing parties were voted out of office, the negotiation were stopped. Nowadays, most people predict that the króna will remain the Icelandic currency for a long time.
A major financial crisis hit Iceland from 2008 to 2011. It brought about a collapse of the Icelandic banking sector. The value of the Icelandic króna dropped, and it went down to around 185 ISK per 1 euro. After many of the issues were resolved, the krónur value went up to around 140 ISK per 1 euro. However, the value hasn't been as high as it was since before the crisis (it was at 82 ISK per 1 euro in mid-2007).
