Marcus Furius Camillus in the context of "Father of the Fatherland"

Pater Patriae (plural Patres Patriae) was an honorific title in ancient Rome. In Latin, it means "father of the country", or more literally, "father of the fatherland".

The title was granted by the Roman Senate. During the Roman Republic, it was given only two times: to Camillus and Cicero. Under the Roman Empire, it was exclusively granted to the Roman emperor, usually after many years of successful rule. Not all emperors were offered the title, while others were offered it but refused to accept. A total of 23 emperors received the title.

Veii (also Veius; Italian: Veio) was an important ancient Etruscan city situated on the southern limits of Etruria and 16 km (9.9 mi) north-northwest of Rome, Italy. It now lies in Isola Farnese, in the comune of Rome. Many other sites associated with and in the city-state of Veii are in Formello, immediately to the north. Formello is named after the drainage channels that were first created by the Veians.

Veii was the richest city of the Etruscan League. It was alternately at war and in alliance with the Roman Kingdom and later Republic for over 300 years. It eventually fell in the Battle of Veii to Roman general Camillus's army in 396 BC. Veii continued to be occupied after its capture by the Romans.

The Temple of Concord, or Temple of Concordia, (Latin: Aedes Concordiae) in Rome refers to a series of temples dedicated to the Roman goddess Concordia, and erected at the western end of the Roman Forum. The Romans believed that the earliest temple was built by Marcus Furius Camillus in 367 BC, but archeological evidence indicates the first shrine to Concordia on the site was constructed in 218 BC by Lucius Manlius Vulso. The temple was rebuilt in 121 BC by Lucius Opimius, following the killing of the Gaius Gracchus and his supporters, and again by the future emperor Tiberius between 7 BC and AD 10.

Triarii (sg.: triarius) ("the third liners") were one of the elements of the early Roman military manipular legions of the early Roman Republic (509 BC – 107 BC). They were the oldest and among the wealthiest men in the army and could afford high quality equipment. They wore heavy metal armor and carried large shields, their usual position being the third battle line. They were equipped with spears and were considered to be elite soldiers among the legion.

During the Camillan era, they fought in a shallow phalanx formation, supported by light troops. In most battles triarii were not used because the lighter troops usually defeated the enemy before the triarii were committed to the battle. They were meant to be used as a decisive force in the battle, thus prompting an old Roman saying: res ad triarios venit, 'it comes down to the triarii', which meant carrying on to the bitter end.
