Marcus Licinius Crassus (/ˈkræsəs/; 115 – 53 BC) was a Roman general and statesman who played a key role in the transformation of the Roman Republic into the Roman Empire. He is often called "the richest man in Rome." Crassus began his public career as a military commander under Lucius Cornelius Sulla during his civil war. Following Sulla's assumption of the dictatorship, Crassus amassed an enormous fortune through real estate speculation. Crassus rose to political prominence following his victory over the slave revolt led by Spartacus, sharing the consulship with his rival Pompey the Great.
