The Lydian Kingdom was an ancient kingdom located in western Asia Minor, in what is now modern-day Turkey. It flourished from the 7th to the 6th century BCE and is known for its rich resources, particularly gold and silver. The kingdom's capital was Sardis, which became a significant cultural and economic center. The Lydians are credited with inventing the first coins, which revolutionized trade and commerce. Under the rule of King Croesus, the kingdom reached its peak, becoming famous for its wealth. The Lydian Kingdom eventually fell to the Persian Empire in the mid-6th century BCE.
