In the Middle Ages, marten skins (kuna = marten) were substitute for money in Croatia.
As real money, the Croatian kuna was introduced in the Independent State of Croatia on 26 July 1941, as replacement for Yugoslav dinar.
The kuna was withdrawn from circulation from 30 June to 9 July, 1945 and replaced by the Yugoslav dinar.
Croatian political emigrants issued propaganda money named Kuna since 1934 till 1989.
The modern kuna was introduced on 30 May 1994, after a transitional period during which the Yugoslav dinar was replaced with the Croatian dinar.
