Fidenae

Conflicts with the Roman kingdom

Originally a settlement of Etruscans, it was for some while the frontier of the Roman territory and from time to time changed hands between Rome and Veii.

In the 8th century BC during the reign of Rome's first king, Romulus, the Fidenates and the Veientes were defeated in a war with Rome, according to legend. It may be that a colony was established there after the defeat as Livy afterwards describes Fidenae as a Roman colony.

Fidenae and Veii were again defeated by Rome in the 7th century BC during the reign of Rome's third king Tullus Hostilius.

Conflicts with the Roman republic

In the early Roman republic Fidenae made a decision that was to cost them much of their land in favor of the new Claudia gens, formed from Sabine defectors. Lucius Tarquinius Superbus, last king of Rome, having been expelled from it, at first looked for intervention from the Etruscans. Lars Porsenna of Clusium, dissatisfied with Superbus' conduct and ethics, made peace with the new republic.

The Tarquins then subverted Latium. Sextus Tarquinius, whose rape of Lucretia had triggered the overthrow of the monarchy (if he was not assassinated at Gabii), convinced the Sabines to go to war against Rome, arguing that previous treaties had been annulled by the expulsion of the kings. The Tarquins were now interested in Latin intervention. After some minor conflicts in which Rome was victorious, the Sabines took a vote and resolved on an invasion of the city of Rome (with perhaps the previous example in memory). The Tarquins brought in Fidenae and Cameria, formerly Roman allies.

The total defeat of the Sabines in 505/504 BC was followed by the siege of Fidenae. When the city was taken only a few days later the Romans assembled their prisoners and executing the senior officers before them (whipped by the rods and beheaded by the axe of the fasces, a standard punishment for treason), let the rest go with a stern warning. A garrison was placed in Fidenae, who were given much of its land. The Claudii are not mentioned in connection with the battle, but they had been given land north of the Anio river, some of which was at Fidenae. They could only collect on that offer if Fidenae was defeated, the implication being that they were being invited to participate in the campaign; they may even have been the garrison.

Fidenae appears to have fallen permanently under Roman domination after its capture in 435 BC by the Romans, and is spoken of by classical authors as a place almost deserted in their time. It seems, however; to have had some importance as a post station. It is also notable for being the site of a deadly amphitheater collapse.

Stadium disaster

In 27 AD, an apparently cheaply built wooden amphitheater, constructed by an entrepreneur named Atilius, collapsed in Fidenae resulting in by far the worst stadium disaster in history with anywhere from 20,000 to 50,000 dead and wounded out of the total audience of 50,000. The emperor Tiberius had banned gladiatorial games, it seems, and when the prohibition was lifted, the public had flocked to the earliest events, and so a large crowd was present when the stadium collapsed. At the time of the incident, Tiberius was in Capreae, where he had a secure getaway, but rushed to Fidenae to assist the victims of this incident. The Roman Senate responded to the tragedy by banning people with a fortune of less than 400,000 sesterces from hosting gladiator shows, and also requiring that all amphitheaters to be built in the future be erected on a sound foundation, inspected and certified for soundness. The government also "banished" Atilius.
