The Spanish Real was the currency used in Spain from the late Middle Ages until the 19th century. It was a silver coin that played a significant role in trade and commerce, especially during the Spanish Empire's expansion. The Real was often minted in various denominations, including the piece of eight, which became widely recognized and used in international trade. The value of the Spanish Real fluctuated over time, influenced by factors such as silver discoveries in the Americas and economic conditions in Europe. Eventually, it was replaced by the peseta in 1868, marking the end of its long-standing use as Spain's primary currency.
