Samnites were quite popular during the period of Roman Republic. Eventually, other gladiator types joined the roster, such as the Gaul and the Thracian. Under the reign of Emperor Augustus, Samnium became an ally and integral part of the Roman Empire (all Italians had by this point gained Roman citizenship). Around this time, the Samnite gladiator fell out of favour, probably because insulting the Samnites was no longer seen as acceptable behaviour. The Samnite was replaced by similarly armed gladiators, including the hoplomachus and the secutor.
