Battle between Roman and Parthian forces (217)
The Battle of Nisibis was fought in the summer of 217 between the armies of the Roman Empire under the newly ascended emperor Macrinus and the Parthian army of King Artabanus IV. It lasted for three days, and ended with a bloody Parthian victory, with both sides suffering large casualties. As a result of the battle, Macrinus was forced to seek peace, paying the Parthians a huge sum and abandoning the invasion of Mesopotamia that Caracalla had begun a year before.
