The blood sports, whose visibility has been maintained in Western civilization today through Hollywood films and video games on gladiators, were a cathartic spectacle that sustained the Roman empire. Because Rome inevitably used brutal war to capture every area that it added to the empire, violence necessarily became the lifeblood of Rome. But also, as various ethnicities, nationalities and classes were brought together, blood sports in the stadiums became one way to keep the empire united through gross displays of valor and power. Gladiators, slaves, prisoners, Christians and wild exotic animals were subjected to torture and excruciating death for the entertainment of the crowds. Scholars say that the games provided an outlet for citizens to express increasingly violent aggression while the state contained the violence within the walls of the colosseum.
