Marcus Licineus Crassus (ca. 115 BC – 53 BC) was a Roman general and politician who wielded considerable influence in the later stages of the Roman Republic. He was general of Sulla's troops in his victory over the Marians, suppressed the slave revolt led by Spartacus and entered into a secret pact, known as the First Triumvirate, with Pompey and Julius Caesar. Getting the legions in Syria as his part of the pact, Crassus dreamed of conquering the Parthian empire, but his efforts at glory ended in disaster when his legions suffered one of the worst defeats in Roman history at the Battle of Carrhae. He died shortly thereafter while still in Parthia.
