Tullus Hostilius in the context of "Kings of Alba Longa"

The gens Curiatia was a distinguished family at Rome, with both patrician and plebeian branches. Members of this gens are mentioned in connection with the reign of Tullus Hostilius, the third King of Rome, during the seventh century BC. The first of the Curiatii to attain any significant office was Publius Curiatius Fistus, surnamed Trigeminus, who held the consulship in 453 BC. The gens continued to exist throughout the Republic, and perhaps into imperial times, but seldom did its members achieve any prominence.

Monte Cavo, or less often, "Monte Albano," is the second highest mountain of the complex of the Alban Hills, near Rome, Italy. An old volcano extinguished around 10,000 years ago, it lies about 20 km (12 mi) from the sea, in the territory of the comune of Rocca di Papa. It is the dominant peak of the Alban Hills. The current name comes from Cabum, an Italic settlement existing on this mountain.

Volcanic activity under King Tullus Hostilius on the site was reported by Livy in his book of Roman history: "...there had been a shower of stones on the Alban Mount...".

Quintus Cloelius Siculus was a Roman Republican politician and patrician during the beginning of the 5th century BC. He served as Consul of Rome in 498 BC together with Titus Larcius.

His gens originated from Alba Longa and had come to Rome under the reign of Tullus Hostilius. He was the first member of his family to serve as consul.

Ancus Marcius (Classical Latin: [ˈaŋkʊs ˈmaːrkiʊs]) was the legendary fourth king of Rome, who traditionally reigned 24 years. Upon the death of the previous king, Tullus Hostilius, the Roman Senate appointed an interrex, who in turn called a session of the assembly of the people who elected the new king. Ancus is said to have ruled by waging war as Romulus did, while also promoting peace and religion as Numa Pompilius did.

Ancus Marcius was believed by many Romans to have been the namesake of the Marcii, a plebeian family.

In the ancient Roman legend of the regal period, the Horatii were three sibling warriors, sons of Publius Horatius (the elder), who lived during the reign of Tullus Hostilius. The accounts of their epic clash with the Curiatii appear in the writings of Livy. The story includes Publius Horatius (the younger), the sole survivor of the battle, murdering his sister for mourning the death of a beloved Curiatius.

Gaius Cluilius was the king of Alba Longa during the reign of the Roman king Tullus Hostilius in the mid seventh century BC. Alba Longa was an ancient city of Latium in central Italy southeast of Rome.

He constructed the Cluilian trench, sometimes referred to as the "Cluilian ditches", which was a huge warfare trench that surrounded the ancient city of Rome approximately four to five miles outside the city walls. It was built for trench warfare and was used in various wars and battles for centuries after the original construction for this very purpose.

The Curia Cornelia was a place where the Roman Senate assembled beginning c. 52 BC. It was the largest of all the Curiae (Senate Houses) built in Rome. Its construction took over a great deal of the traditional comitium space and brought the senate building into a commanding location within the Roman Forum as a whole. It was the Senate House of the time of Julius Caesar and is significant because its location was moved by him to diminish the Senate's dominance within the City and Republic.

The Curia Hostilia was one of the original senate houses or "curiae" of the Roman Republic. It was believed to have begun as a temple where the warring tribes laid down their arms during the reign of Romulus (r. c. 771–717 BC). During the early monarchy, the temple was used by senators acting as a council to the king. Tullus Hostilius (r. 673–641 BC) was believed to have replaced the original structure after fire destroyed the converted temple. It may have held historic significance as the location of an Etruscan mundus and altar. The Lapis Niger, a series of large black marble slabs, was placed over the altar (known as the Volcanal) where a series of monuments was found opposite the Rostra. This curia was enlarged in 80 BC by Lucius Cornelius Sulla during his renovations of the comitium. That building burned down in 52 BC when the supporters of the murdered Publius Clodius Pulcher used it as a pyre to cremate his body.
