When and where was the first currency note used?

The first currency note was used in China during the Tang Dynasty (618-907 AD). These early notes were called "jiaozi" and were introduced in the 7th century. The first paper money was created in 1260 by Kublai Khan, the founder of the Yuan Dynasty, to finance his military campaigns. These notes were called "chao" and were used to replace copper coins. In Europe, the first paper money was introduced in Sweden in 1661 by the Stockholm Banco, a private bank. These notes were called "kreditivsedlar" and were used to reduce the need for copper coins. The first paper money issued by a central bank was introduced in England in 1693 by the Bank of England. These notes were called "banknotes" and were used to finance the government's military expenses. The United States introduced its first paper money in 1690, called "bills of credit," to finance military expenses during King William's War. However, these notes were not widely accepted and were eventually replaced by coins. The first widely accepted paper money in the United States was introduced in 1861, during the Civil War, called "greenbacks." These notes were issued by the federal government to finance its war efforts and were widely accepted as a form of payment. So, to summarize: - China: 7th century (jiaozi) - China (Yuan Dynasty): 1260 (chao) - Sweden: 1661 (kreditivsedlar) - England: 1693 (banknotes) - United States: 1690 (bills of credit), 1861 (greenbacks)
