Roman Emperor in the context of "Bar Kokhba revolt coinage"

Shkodër (/ˈʃkoʊdər/ SHKOH-dər, Albanian: [ˈʃkɔdəɾ]; Albanian definite form: Shkodra; historically known as Scodra or Scutari) is the fifth-most-populous city of Albania and the seat of Shkodër County and Shkodër Municipality. Shkodër has been continuously inhabited since the Early Bronze Age (c. 2250–2000 BC), and has roughly 2,200 years of recorded history. The city sprawls across the Plain of Mbishkodra between the southern part of Lake Shkodër and the foothills of the Albanian Alps on the banks of the Buna, Drin and Kir rivers. Due to its proximity to the Adriatic Sea, Shkodër is affected by a seasonal Mediterranean climate with continental influences.

An urban settlement called Skodra was founded by the Illyrian tribe of Labeatae in the 4th century BCE. It became the capital of the Illyrian kingdom under the Ardiaei and Labeatae and was one of the most important cities of the Balkans in ancient times. It has historically developed on a 130 m (430 ft) hill strategically located in the outflow of Lake Shkodër into the Buna. The Romans annexed the city after the third Illyrian War in 168 BC, when the Illyrian king Gentius was defeated by the Roman force of Anicius Gallus. In the 3rd century AD, Shkodër became the capital of Praevalitana, due to the administrative reform of the Roman Emperor Diocletian. With the spread of Christianity in the 4th century AD, the Archdiocese of Scodra was founded and was assumed in 535 by Byzantine Emperor Justinian I.

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.

Meditations (Koine Greek: Τὰ εἰς ἑαυτόν, romanized: Ta eis heauton, lit. ''Things Unto Himself'') is a series of personal writings by Marcus Aurelius, Roman Emperor from 161–180 CE, recording his private notes to himself and ideas on Stoic philosophy.

In ancient Greek religion and mythology, Helios (/ˈhiːliəs, -ɒs/; Ancient Greek: Ἥλιος pronounced [hɛ̌ːlios], lit. 'Sun'; Homeric Greek: Ἠέλιος) is the god who personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol. The Roman Emperor Julian made Helios the central divinity of his short-lived revival of traditional Roman religious practices in the 4th century AD.

Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described as the son of the Titans Hyperion and Theia and brother of the goddesses Selene (the Moon) and Eos (the Dawn). Helios's most notable role in Greek mythology is the story of his mortal son Phaethon. In the Homeric epics, his most notable role is the one he plays in the Odyssey, where Odysseus's men despite his warnings impiously kill and eat Helios's sacred cattle that the god kept at Thrinacia, his sacred island. Once informed of their misdeed, Helios, in wrath, asks Zeus to punish those who wronged him, and Zeus, agreeing, strikes their ship with a thunderbolt, killing everyone except Odysseus himself, the only one who had not harmed the cattle and was allowed to live.

The Library of Celsus (Greek: Βιβλιοθήκη του Κέλσου) is an ancient Roman building in Ephesus, Anatolia, located near the modern town of Selçuk, in the İzmir Province of western Turkey. The building was commissioned in the years 110s CE by a consul of the Roman Empire, Tiberius Julius Aquila Polemaeanus, as a funerary monument for his father Tiberius Julius Celsus Polemaeanus, former proconsul of Asia, and completed during the reign of the Roman Emperor Hadrian, sometime after Aquila's death.

The Library of Celsus is considered an architectural marvel, and is one of the few remaining examples of great libraries of the ancient world located in the Roman Empire. It was the third-largest library in the Greco-Roman world behind only those of Alexandria and Pergamum, and is believed to have held around 12,000 scrolls. Celsus is buried in a crypt beneath the library in a decorated marble sarcophagus. The interior measured roughly 180 square metres (2,000 square feet).

The Roman campaigns in Germania (12 BC – AD 16) were a series of conflicts between the Germanic tribes and the Roman Empire. Tensions between the Germanic tribes and the Romans began as early as 17/16 BC with the Clades Lolliana, where the 5th Legion under Marcus Lollius was defeated by the tribes Sicambri, Usipetes, and Tencteri. Roman Emperor Augustus responded by rapidly developing military infrastructure across Gaul. His general, Nero Claudius Drusus, began building forts along the Rhine in 13 BC and launched a retaliatory campaign across the Rhine in 12 BC.

Drusus led three more campaigns against the Germanic tribes in the years 11–9 BC. For the campaign of 10 BC, he was celebrated for being the Roman who traveled farthest east in northern Europe. Succeeding generals would continue attacking across the Rhine until AD 16, notably Publius Quinctilius Varus in AD 9. During the return trip from his campaign, Varus' army was ambushed and almost destroyed by a Germanic force led by Arminius at the Battle of the Teutoburg Forest; Arminius was the leader of the Cherusci, had previously fought in the Roman army, and was considered by Rome to be an ally. Roman expansion into Germania Magna stopped as a result, and all campaigns immediately after were in retaliation of the Clades Variana ("Varian Disaster"), the name used by Roman historians to describe the Battle of the Teutoburg Forest, and to prove that Roman military might could still overcome German lands. The last general to lead Roman forces in the region during this time was Germanicus, the adoptive son of Emperor Tiberius, who in AD 16 had launched the final major military expedition by Rome into Germania.

Sebastus (Ancient Greek: σεβαστός lit. 'venerable one, augustus', [sevasˈtos]) was an honorific used by the ancient Greek to render the Roman imperial title of Augustus. The female form of the title was sebaste (σεβαστή). It was revived as an honorific in the 11th century Byzantine Empire and came to form the basis of a new system of court titles. From the Komnenian period onwards, the Byzantine hierarchy included the title sebastos and variants derived from it, like sebastokrator, protosebastos, panhypersebastos, and sebastohypertatos.

The Constitution of the Roman Empire was an unwritten set of guidelines and principles passed down mainly through precedent. After the fall of the Roman Republic, the constitutional balance of power shifted from the Roman Senate to the Roman Emperor. Beginning with the first emperor, Augustus, the emperor and the Senate were theoretically two co-equal branches of government. In practice, however, the actual authority of the imperial Senate was negligible, as the emperor held the true power of the state. During the reign of the second emperor, Tiberius, many of the powers that had been held by the Roman assemblies were transferred to the Senate.

The powers of an emperor existed by virtue of his legal standing. The two most significant components to an emperor's power were the "tribunician powers" Latin: tribunicia potestas and the proconsular imperium, or the power to command. The tribunician powers gave the emperor authority over Rome itself and the civil government, while the proconsular powers gave him authority over the provinces and the army. While these distinctions were clearly defined during the early empire, eventually they were lost, and the emperor's powers became less constitutional and more monarchical. The traditional magistracies that survived the fall of the Republic were the Consulship, Praetorship, Plebeian Tribunate, Aedileship, Quaestorship, and Military Tribunate. Any individual of the senatorial class could run for one of these offices. If an individual was not of the senatorial class, he could run for one of these offices if he was allowed to run by the emperor, or otherwise, he could be appointed to one of these offices by the emperor.

The title of imperator (/ˌɪmpəˈrɑːtər/ im-pə-RAH-tər) originally meant the rough equivalent of commander under the Roman Republic. Later, it became a part of the titulature of the Roman Emperors as their praenomen. The Roman emperors generally based their authority on multiple titles and positions, rather than preferring any single title. Nevertheless, imperator was used relatively consistently as an element of a Roman ruler's title throughout the Principate and the later Roman Empire. It was abbreviated to "IMP" in inscriptions. The word derives from the stem of the verb imperare, meaning 'to order, to command'. The English word emperor derives from imperator via Old French: Empereür.
