In short
In 53 BCE, the Roman general Crassus led a major military expedition into Mesopotamia against the Parthian Empire and was decisively defeated at Carrhae (in present-day Turkey). The battle killed around 20,000 Roman soldiers and marked a catastrophic end to Rome's eastward expansion, establishing the Euphrates as a long-term frontier between two superpowers.
