Marcus Licinius Crassus in the context of "Julius Caesar"

The Kingdom of Dardania (Latin: Regnum Dardaniae) was a polity in the central Balkans in the region of Dardania during classical antiquity. It is named after the Dardani, a Paleo-Balkan tribe that formed the core of the Dardanian polity. Dardania was centered around present-day Kosovo, but also included parts of North Macedonia (northwestern area) and Albania (Kukës, Tropoja, Has). The eastern parts of Dardania were at the Thraco-Illyrian contact zone. Marcus Licinius Crassus, grandson of the triumvir Marcus Crassus, officially annexed the kingdom in 28 BC while on campaign against the Dacians and Bastarnae. The region was subsequently incorporated into the province of Moesia in 15 BC, and later in 293 AD, as the province of Dardania.

Marcus Licinius Crassus (fl. 1st century BC), grandson of the triumvir Marcus Licinius Crassus, was a Roman consul in the year 30 BC as the colleague of Octavian (the future Roman Emperor Augustus). He was best known for his successful campaigns in Macedonia and Thrace in 29–27 BC, for which he was denied customary military honors by Augustus.

The younger Crassus was the son of another Marcus Licinius Crassus, possibly by his wife Caecilia Metella Cretica, daughter of the consul Quintus Caecilius Metellus Creticus (see Caecilius Metellus); his mother's tomb is visible on the Appian Way. His father was a quaestor to Julius Caesar, and a son of Marcus Licinius Crassus possibly by his wife Tertulla (widow of an elder brother killed in December 87 BC). Crassus apparently had no surviving sons by his wife. It is believed that he adopted the future consul Marcus Licinius Crassus Frugi from the Calpurnii Pisones family.

The Battle of Carrhae (Latin pronunciation: [ˈkar.rʰae̯]) was fought in 53 BC between the Roman Republic and the Parthian Empire near the ancient town of Carrhae (present-day Harran, Turkey). An invading force of seven legions of Roman heavy infantry under Marcus Licinius Crassus was lured into the desert and decisively defeated by a mixed cavalry army of heavy cataphracts and light horse archers led by the Parthian general Surena. On such flat terrain, the legion proved to have no viable tactics against the highly mobile Parthian horsemen, and the slow and vulnerable Roman formations were surrounded, exhausted by constant attacks, and eventually crushed. Crassus was killed along with most of his army. It is commonly seen as one of the earliest and most important battles between the Roman and Parthian Empires and one of the most crushing defeats in Roman history. According to the poet Ovid in Book 6 of his poem Fasti, the battle occurred on 9 June.

Crassus, a member of the First Triumvirate and the wealthiest man in Rome, had been enticed by the prospect of military glory and riches and decided to invade Parthia without the official consent of the Senate. Rejecting an offer from the Armenian King Artavasdes II to allow Crassus to invade Parthia via Armenia, Crassus marched his army directly through the deserts of Mesopotamia. His forces clashed with Surena's troops near Carrhae. Surena's cavalry killed or captured most of the Roman soldiers. Crassus himself was killed when truce negotiations turned violent, and his death ended the First Triumvirate.

The First Triumvirate (c. late 60 – 53 BC) was an informal political alliance among three prominent politicians in the late Roman Republic: Gnaeus Pompeius Magnus, Marcus Licinius Crassus, and Gaius Julius Caesar. The republican constitution had many veto points. In order to bypass constitutional obstacles and force through the political goals of the three men, they forged an alliance in secret where they promised to use their respective influence to support each other. The "triumvirate" was not a formal magistracy, nor did it achieve a lasting domination over state affairs.

It was formed among the three men due to their mutual need to overcome opposition in the senate against their proposals in the previous years. Initially secret, it emerged publicly during Caesar's first consulship in 59 BC to push through legislation for the three allies. Caesar secured passage of an agrarian law which helped resettle Pompey's veterans, a law ratifying Pompey's settlements after the Third Mithridatic War, and legislation on provincial administration and tax collection. Caesar also was placed in a long-term governorship in Gaul. The early success of the alliance, however, triggered substantial political backlash. Political alliances at Rome reorganised to counterbalance the three men in the coming years.

In the Roman Republic, triumviri or tresviri were commissions of three men appointed for specific tasks. There were many tasks that commissions could be established to conduct, such as administer justice, mint coins, support religious tasks, or found colonies.

Most commonly, when historians refer to Roman "triumvirs", they mean two political alliances during the crisis of the Roman Republic. The informal First Triumvirate of Julius Caesar, Pompey the Great, and Marcus Licinius Crassus was a loose political alliance arranged in 60 or 59 BC that lasted until the death of Crassus in the Battle of Carrhae in 53 BC; they had no official capacity or function as actual triumviri, and the term is used as a nickname.

The Temple of Mars Ultor was a sanctuary erected in Ancient Rome by the Roman Emperor Augustus in 2 BCE and dedicated to the god Mars in his guise as avenger. The centerpiece of the Forum of Augustus, it was a peripteral style temple, on the front and sides, but not the rear (sine postico), raised on a platform and lined with eight columns in the Corinthian order style.

According to Suetonius and Ovid, the young Octavian vowed to build a temple to Mars in 42 BCE just before the Battle of Philippi if the god would grant him and Marcus Antonius victory over two of the assassins of Julius Caesar, Gaius Cassius Longinus and Marcus Junius Brutus. However, work did not commence on the temple until after the recovery of the Aquilae in 20 BCE that had been lost by Marcus Licinius Crassus in the disastrous Battle of Carrhae 33 years earlier. Originally, the Roman Senate had decreed that the returned standards were to be housed in a temple to Mars Ultor that was to be built on the Capitoline Hill. Augustus however, declared that he would build it at his own expense on the site of his new forum. Augustus’s decision to wait to fulfill his vow has been speculated to have been due to a reluctance to celebrate his victory over those who were seen as the defenders of Libertas, whereas the return of the standards, and its symbolic revenge against the Parthians, was a more acceptable victory to commemorate.
