Augustus in the context of "Moesia"

The denarius (Latin: [deːˈnaːriʊs]; pl.: dēnāriī, Latin: [deːˈnaːriiː]) was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III (AD 238–244), when it was gradually replaced by the antoninianus. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the Tetrarchy (293–313).

The word dēnārius is derived from the Latin dēnī "containing ten", as its value was originally of 10 assēs. The word for "money" descends from it in Italian (denaro), Slovene (denar), Portuguese (dinheiro), and Spanish (dinero). Its name also survives in the dinar currency.

The Roman provinces (Latin: provincia, pl. provinciae) were the administrative regions of Ancient Rome outside Roman Italy that were controlled by the Romans under the Roman Republic and later the Roman Empire. Each province was ruled by a Roman appointed as governor.

For centuries, it was the largest administrative unit of the foreign possessions of ancient Rome. With the administrative reform initiated by Diocletian, it became a third level administrative subdivision of the Roman Empire, or rather a subdivision of the imperial dioceses (in turn subdivisions of the imperial prefectures).

The Battle of Actium was a naval battle fought between Octavian's maritime fleet, led by Marcus Agrippa, and the combined fleets of both Mark Antony and Cleopatra. The battle took place on 2 September 31 BC in the Ionian Sea, near the former Roman colony of Actium, Greece, and was the climax of over a decade of rivalry between Octavian and Mark Antony.

In early 31 BC, the year of the battle, Antony and Cleopatra were temporarily stationed in Greece. Mark Antony possessed 500 ships and 70,000 infantry and made his camp at Actium, while Octavian, with 400 ships and 80,000 infantry, arrived from the north and occupied Patrae and Corinth, where, with the help of Marcus Vipsanius Agrippa, he managed to cut Antony's southward communications with Egypt via the Peloponnese. Octavian had previously gained a preliminary victory in Greece, where his navy successfully ferried troops across the Adriatic Sea under the command of Agrippa. Octavian landed on mainland Greece, opposite the island of Corcyra (modern Corfu), and proceeded south on land.

The War of Actium (32–30 BC) was the last civil war of the Roman Republic, fought between Mark Antony (assisted by Cleopatra and by extension Ptolemaic Egypt) and Octavian. In 32 BC, Octavian convinced the Roman Senate to declare war on the Egyptian queen Cleopatra. Her lover and ally Mark Antony, who was Octavian's rival, gave his support for her cause. Forty percent of the Roman Senate, together with both consuls, left Rome to join the war on Antony's side. After a decisive victory for Octavian at the Battle of Actium, Cleopatra and Antony withdrew to Alexandria, where Octavian besieged the city until both Antony and Cleopatra were forced to commit suicide.

The war involved some of the largest Roman armies ever seen. Both Antony and Octavian's legions were experienced veterans of previous civil wars who had fought together, many also having once served under Julius Caesar. The two did however raise their own legions separately.

The wars of Augustus are the military campaigns undertaken by the Roman government during the sole rule of the founder-emperor Augustus (30 BC – AD 14). This was a period of 45 years when almost every year saw major campaigning, in some cases on a scale comparable to the Second Punic War (218–201 BC), when Roman manpower resources were stretched to the limit. This period also saw expansion through diplomacy and annexation, without the direct use of military force. The result was a major expansion of the empire that Augustus inherited from the Roman Republic, although the attempted conquest of Germania ended in defeat despite the enormous deployment of resources involved. As a result of these campaigns, the Roman Empire assumed the borders it would hold, with a few modifications, for its entire history.

Augustus (plural Augusti; /ɔːˈɡʌstəs/ aw-GUST-əs, Classical Latin: [au̯ˈɡʊstʊs]; "majestic", "great" or "venerable") was the main title of the Roman emperors during Antiquity. It was given as both name and title to Gaius Julius Caesar Octavianus (often referred to simply as Augustus) in 27 BC, marking his accession as Rome's first emperor. On his death, it became an official title of his successor, and was so used by all emperors thereafter. The feminine form Augusta was used for Roman empresses and other female members of the imperial family. The masculine and feminine forms originated in the time of the Roman Republic, in connection with things considered divine or sacred in traditional Roman religion. Their use as titles for major and minor Roman deities of the Empire associated the imperial system and family with traditional Roman virtues and the divine will and may be considered a feature of the Roman imperial cult.

In Rome's Greek-speaking provinces, "Augustus" was translated as Sebastos (Σεβαστός), or Hellenised as Augoustos (Αὔγουστος); these titles continued to be used in the Byzantine Empire until the Fall of Constantinople in 1453, although they gradually lost their imperial exclusivity in favour of Basileus and Autokrator.

The constitutional reforms of Augustus were a series of laws that were enacted by the Roman Emperor Augustus between 30 BC and 2 BC, which transformed the Constitution of the Roman Republic into the Constitution of the Roman Empire. The era during which these changes were made began when Augustus defeated Mark Antony and Cleopatra at the Battle of Actium in 31 BC, and ended when the Roman Senate granted Augustus the title "Pater Patriae" in 2 BC.

A legate (Latin: legatus, Classical Latin: [ɫeːˈɡaːtʊs]) was a high-ranking military officer in the Roman army, equivalent to a modern-era general officer. Initially used to delegate power, the term became formalised under Augustus as the officer in command of a Roman legion.

From the times of the Roman Republic, legates received large shares of the military's rewards at the end of a successful campaign. This made the position a lucrative one, so it could often attract even distinguished consuls or other high-ranking political figures within Roman politics (e.g., the consul Lucius Julius Caesar volunteered late in the Gallic Wars as a legate under his first cousin, Gaius Julius Caesar).
