Where is a kuna from?

Excuse me, but could you please clarify the origin of the kuna for me? I'm not entirely familiar with this particular currency, and I'm curious to know more about its geographical and economic context. Is it a national currency of a particular country, or is it used in a regional or international capacity? Additionally, I'd appreciate it if you could share any insights into its history and significance within the global financial landscape. Thank you in advance for your assistance.
