Manius Otacilius Crassus was a Roman statesman and general of Samnite origins who served during the middle era of the Roman Republic.[1] He was one of the two consuls of 263 BCE, serving with Manius Valerius Maximus Corvinus Messalla. During their consulship they fought in the First Punic War on Sicily.[2] Their first campaign was against Syracuse; Hieron of Syracuse negotiated terms (paying an indemnity, supporting Rome's war effort against Carthage, but remaining independent).[3] They then marched against the Carthaginians; receiving the surrender of several Greek communities who were previously aligned with Carthage. He was consul for the second time in 246 BCE, serving with Marcus Fabius Licinus.
