Quick Summary

The Mermnad dynasty ruled ancient Lydia, a region in western Anatolia that extended from the Aegean Sea. The Lydians are credited with inventing gold and silver coins, which significantly impacted Greek civilization in the 6th century BCE.1

The Mermnad dynasty was established by King Gyges in the 7th century BCE, following the destruction of Phrygia by the Cimmerians. The kingdom reached its peak under King Alyattes, who expanded Lydian rule into Ionia. His son, Croesus, known for his immense wealth, continued to expand the kingdom. However, the Mermnad dynasty's rule came to an end around 546–540 BCE when the Persian king Cyrus the Great conquered Lydia. The Lydians were a commercial people known for establishing permanent retail shops.12
