Augustus in the context of Museum of the Ara Pacis

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).

The history of the Roman Empire covers the history of ancient Rome from the traditional end of the Roman Republic in 27 BC until the abdication of Romulus Augustulus in AD 476 in the West, and the Fall of Constantinople in the East in 1453. Ancient Rome became a territorial empire while still a republic but was then ruled by emperors, beginning with Octavian Augustus, the final victor of the republican civil wars.

Rome had begun expanding shortly after the founding of the Republic in the 6th century BC, though it did not expand outside the Italian Peninsula until the 3rd century BC, during the Punic Wars, after which the Republic expanded across the Mediterranean. Civil war engulfed Rome in the mid-1st century BC, first between Julius Caesar and Pompey, and finally between Octavian (Caesar's grand-nephew) and Mark Antony. Antony was defeated at the Battle of Actium in 31 BC, leading to the annexation of Egypt. In 27 BC, the Senate gave Octavian the titles of Augustus ("venerated") and Princeps ("foremost"), thus beginning the Principate, the first epoch of Roman imperial history. Augustus' name was inherited by his successors, as well as his title of Imperator ("commander"), from which the term "emperor" is derived. Early emperors avoided any association with the ancient kings of Rome, instead presenting themselves as leaders of the Republic.

The Palatine Hill (/ˈpælətaɪn/; Classical Latin: Palatium; Neo-Latin: Collis/Mons Palatinus; Italian: Palatino [palaˈtiːno]), which relative to the seven hills of Rome is the centremost, is one of the most ancient parts of the city; it has been called "the first nucleus of the Roman Empire". The site is now mainly a large open-air museum whilst the Palatine Museum houses many finds from the excavations here and from other ancient Italian sites.

Imperial palaces were built there, starting with Augustus. Before imperial times the hill was mostly occupied by the houses of the rich.

A heroön or heroon (plural heroa) (/hɪˈroʊ.ɒn/; Ancient Greek: ἡρῷον, romanized: hērôion, pl. ἡρῷα, hērôia), also Latinized as heroum, is a shrine dedicated to an ancient Greek or Roman hero and used for the commemoration or cult worship of the hero. They were often erected over their supposed tomb or cenotaph. They were erected from the time of archaic Greece to the Augustan Roman period, and as far afield as Ai-Khanoum in Afghanistan.

Publius Ovidius Naso (Latin: [ˈpuːbliʊs ɔˈwɪdiʊs ˈnaːsoː]; 20 March 43 BC – AD 17/18), known in English as Ovid (/ˈɒvɪd/ OV-id), was a Roman poet who lived during the reign of Augustus. He was a younger contemporary of Virgil and Horace, with whom he is often ranked as one of the three canonical poets of Latin literature. The Imperial scholar Quintilian considered him the last of the Latin love elegists. Although Ovid enjoyed enormous popularity during his lifetime, the emperor Augustus exiled him to Tomis, the capital of the newly organised province of Moesia, on the Black Sea, where he remained for the last nine or ten years of his life. Ovid himself attributed his banishment to a carmen et error ("poem and a mistake"), but his reluctance to disclose specifics has resulted in much speculation among scholars.

Ovid is most famous for the Metamorphoses, a continuous mythological narrative in fifteen books written in dactylic hexameters. He is also known for works in elegiac couplets such as Ars Amatoria ("The Art of Love") and Fasti. His poetry was much imitated during Late Antiquity and the Middle Ages, and greatly influenced Western art and literature. The Metamorphoses remains one of the most important sources of classical mythology today.

In ancient Roman religion and mythology, Mars (Latin: Mārs, pronounced [maːrs]) is the god of war and also an agricultural guardian, a combination characteristic of early Rome. He is the son of Jupiter and Juno, and was pre-eminent among the Roman army's military gods. Most of his festivals were held in March, the month named for him (Latin Martius), and in October, the months which traditionally began and ended the season for both military campaigning and farming.

Under the influence of Greek culture, Mars was identified with the Greek god Ares, whose myths were reinterpreted in Roman literature and art under the name of Mars. The character and dignity of Mars differs in fundamental ways from that of his Greek counterpart, who is often treated with contempt and revulsion in Greek literature. Mars's altar in the Campus Martius, the area of Rome that took its name from him, was supposed to have been dedicated by Numa, the peace-loving semi-legendary second king of Rome; in Republican times it was a focus of electoral activities. Augustus shifted the focus of Mars's cult to within the pomerium (Rome's ritual boundary), and built a temple to Mars Ultor as a key religious feature of his new forum.

Llívia (Catalan pronunciation: [ˈʎiβiə]; Spanish: Llivia Spanish: [ˈʎiβja] ) is a town in the comarca of Cerdanya, province of Girona, Catalonia, Spain. It is a Spanish exclave surrounded by the French département of Pyrénées-Orientales. It is named after Livia, the wife of Augustus and matriarch of the Julio-Claudian dynasty. Because of a technicality in the Treaty of the Pyrenees, signed in 1659, that transferred only "villages" in the Pyrenees to France, Llívia, which was a "town", remains under Spanish control. The Segre river, a tributary of the Spanish Ebro, flows through Llívia. It has a population of 1,560 (register office, 2024) .

Llívia is separated from the rest of Spain by a corridor approximately 1.6 km (1.0 mile) wide, which includes the French communes of Ur and Bourg-Madame. This corridor is traversed by a road, owned by both France (where it is part of Route nationale 20 and RD68) and Spain (where it is part of N-154). Before the implementation of the Schengen Area in 1995, it was considered a "neutral road", a custom-free route with access for both French and Spanish people; since 1995, there have been no formal borders. The two countries share a hospital in Puigcerdà (which lies close to Llívia), as well as other local initiatives.

Hellenistic Greece is the historical period of Ancient Greece following Classical Greece and between the death of Alexander the Great in 323 BC and the annexation of the classical Greek Achaean League heartlands by the Roman Republic. This culminated at the Battle of Corinth in 146 BC, a crushing Roman victory in the Peloponnese that led to the destruction of Corinth and ushered in the period of Roman Greece. Hellenistic Greece's definitive end was with the Battle of Actium in 31 BC, when Octavian defeated Ptolemaic queen Cleopatra VII and Mark Antony, the next year taking over Alexandria, the last great center of Hellenistic Greece.

The Hellenistic period began with the wars of the Diadochi, armed contests among the former generals of Alexander the Great to carve up his empire in Europe, Asia, and North Africa. The wars lasted until 275 BC, witnessing the fall of both the Argead and Antipatrid dynasties of Macedonia in favor of the Antigonid dynasty. The era was also marked by successive wars between the Kingdom of Macedonia, the kingdom of Epirus, the Aetolian League, Achaean League, Sparta, Rhodes, kingdom of Pergamum as well as the Seleucid and Ptolemaic empires.

Cleopatra VII, the last ruler of the Ptolemaic Kingdom of Egypt, died on either 10 or 12 August, 30 BC, in Alexandria, when she was 39 years old. According to popular belief, Cleopatra killed herself by allowing an asp (Egyptian cobra) to bite her, but according to the Roman-era writers Strabo, Plutarch, and Cassius Dio, Cleopatra poisoned herself using either a toxic ointment or by introducing the poison with a sharp implement such as a hairpin. Modern scholars debate the validity of ancient reports involving snakebites as the cause of death and whether she was murdered. Some academics hypothesize that her Roman political rival Augustus (Octavian) forced her to kill herself in a manner of her choosing. The location of Cleopatra's tomb is unknown. It was recorded that Octavian allowed for her and her husband, the Roman politician and general Mark Antony, who stabbed himself with a sword, to be buried together properly.

Cleopatra's death effectively ended the final war of the Roman Republic between the remaining triumvirs Octavian and Antony, in which Cleopatra aligned herself with Antony, father to three of her children. Antony and Cleopatra fled to Egypt following their loss at the 31 BC Battle of Actium in Roman Greece, after which Octavian invaded Egypt and defeated their forces. Committing suicide allowed her to avoid the humiliation of being paraded as a prisoner in a Roman triumph celebrating the military victories of Octavian, who would become Rome's first emperor in 27 BC and be known as Augustus. Octavian, rival heir of Julius Caesar had Cleopatra's son Caesarion (also known as Ptolemy XV) killed in Egypt but spared her children with Antony and brought them to Rome. Cleopatra's death marked the end of the Hellenistic period and Ptolemaic rule of Egypt, as well as the beginning of Roman Egypt, which became a province of the Roman Empire.

Judaea was a Roman province from 6 to 135 AD, which at its height encompassed the regions of Judea, Idumea, Peraea, Samaria, and Galilee, as well as parts of the coastal plain of the southern Levant. At its height, it encompassed much of the core territories of the former Kingdom of Judaea, which had been ruled by the Hasmonean and Herodian dynasties in previous decades. The name Judaea (like the similar Judea) derives from the Iron Age Kingdom of Judah, which was centered in the region of Judea.

Since the Roman Republic's conquest of Judaea in 63 BC, which abolished the independent Hasmonean monarchy, Rome maintained a system of semi-autonomous vassalage in the region. After Hasmonean ruler Antigonus II Mattathias briefly regained the throne, he was overthrown by Herod, who was appointed King of the Jews by the Roman Senate and ruled Judaea until his death in 4 BC. The province's formal incorporation into the Roman Empire was enacted by Augustus in 6 AD following an appeal by the populace against the misrule of Herod's son, Herod Archelaus (r. 4 BC – 6 Anno Domini Nostri). The administrative capital was relocated from Jerusalem to the coastal city of Caesarea Maritima.

Titus Livius (Latin: [ˈtɪtʊs ˈliːwiʊs]; 59 BC – AD 17), known in English as Livy (/ˈlɪvi/ LIV-ee), was a Roman historian. He wrote a monumental history of Rome and the Roman people, titled Ab Urbe Condita, ''From the Founding of the City'', covering the period from the earliest legends of Rome before the traditional founding in 753 BC through the reign of Augustus in Livy's own lifetime. He was on good terms with members of the Julio-Claudian dynasty and was a friend of Augustus. Livy encouraged Augustus’s young grandnephew, the future emperor Claudius, to take up the writing of history.
