The Battle of Carrhae 53BC was an important battle between the Roman Republic and the Parthian Empire and a decisive victory for the Parthians.

Crassus, commander of the Roman forces, was a member of the First Triumvirate and the wealthiest man in Rome, had been enticed by the prospect of military glory and riches and decided to invade Parthia without the official consent of the Senate. Rejecting an offer from the Armenian King Artavasdes II to invade Parthia via Armenia, Crassus marched his army directly through the deserts of Mesopotamia. His army clashed with Surena's force near Carrhae, a small town in modern-day Turkey. Despite being heavily outnumbered, Surena's cavalry completely outmanoeuvred the Roman heavy infantry, killing or capturing most of the Roman soldiers. Crassus himself was killed when truce negotiations turned violent. His death led to the end of the First Triumvirate and the resulting civil wars between Julius Caesar and Pompey.
