Eucratides I (c. 171–145 BCE) was one of the most powerful rulers of the Greco-Bactrian Kingdom, ruling much of Bactria and extending his authority into parts of present-day Afghanistan and northwestern India. He founded the Eucratid dynasty after overthrowing the previous ruling house and is renowned for issuing an extensive and impressive coinage, including some of the largest gold coins of the ancient world. Despite his military successes, his kingdom was weakened by continual warfare, and according to ancient sources he was ultimately murdered by his own son, marking the beginning of the decline of Greco-Bactrian power.
