Born into a senatorial family but lacking any talent for politics, Gaius Cassius Longinus found soldiering more to his liking and joined the triumvir Crassus on his doomed expedition against the Parthians in 53 BC. Cassius managed to rescue himself and a handful of others from the massacre and escaped to Roman Syria, where he remained for another two years ably defending the province from Parthian attack. He returned to Rome as a war hero in 51 BC and fell in with the Pompeian faction, serving as commander of Pompey's fleet during the civil war of 49-48 BC. After Pompey's defeat and death, Cassius accepted a pardon from Caesar and loyally served him for the next four years. Cassius perhaps hoped to attain supreme power once Caesar retired, but it soon became apparent the dictator had no intention of stepping down. Thus, Cassius suborned his close friend Marcus Junius Brutus and several other senators into a conspiracy, and he was one of the first to plunge his dagger into Caesar on the Ides of March, 44 BC. After fleeing Rome with the other conspirators, Cassius returned to Syria and commandeered several legions and a fleet, which he used to attack and pillage the wealthy island of Rhodes in order to procure gold for the approaching civil war. He joined forces with Brutus in 42 BC and the two marched into Thrace to meet the pro-Caesarian legions led by Mark Antony and Octavian. Though their army outnumbered the Caesarians, Cassius and Brutus seemed oddly fatalistic and made a suicide pact should either meet defeat or capture. At the first clash at Philippi in early October, Cassius suffered a loss and rashly fell on his sword before he could be told that Brutus had counterattacked and saved the day. Demoralized by his friend's death, Brutus was easily defeated three weeks later and took his own life.

The obverse of this denarius closely copies the reverse of the aureus struck by M. Aquinius, and was probably minted on the occasion of the meeting in Smyrna between Cassius and Brutus. The capis and lituus, symbols of the pontificate, recall Spinther's election to that college in 57 BC.

Brutus is best known for his role in the assassination of Julius Caesar on March 15, 44 BC. This action, while often thought as an attempt to save liberty and justice, was actually meant to try to preserve aristocracy and privilege. Brutus and the other conspirators wanted to restore power to the Senate, comprised of the wealthiest and most powerful of Roman citizens. This brought him in conflict with Julius Caesar, who wanted to break the old power holds in the Senate, populating it with men of lower rank and birth. In a way, Julius Caesar could be seen as promoting a dictatorship with some flavor of a democracy, whereas Brutus and the other conspirators were attempting to save the aristocracy.

After their assassination of Julius Caesar, Brutus and Cassius occupied Rome but had to flee when a funeral oration delivered by Caesar's protégé, Marc Antony, turned public opinion against them. Brutus and Cassius went their separate ways but met again in early 42 BC in Smyrna, Ionia, where they began preparations for the inevitable conflict that would ensue between them and Marc Antony and Octavian, Caesar's grandnephew. They began using their armies to conquer cities, for which this series of coins was undoubtedly issued. The title IMP on the reverse shows that Brutus still styled himself the savior of the Republic, as that was a title only the Senate could award.
