The Roman Empire was a political-military domain exercised by the Roman civilization over part of Europe, Africa, and the Near East between the year 27 BC and the year 476 AD It represents the third period of Roman civilization and the last stage of Classical Antiquity.
It begins with the coming to power of Octavio Augusto, the first Roman leader to concentrate all political, religious, and military powers. The now emperor left behind the model of the republic and launched an expansive political project.
Standard of the Roman Empire.
The Roman Empire controlled the entire Mediterranean area and its adjacencies. This means that their domains extended to almost all of Europe, much of the Near East (Western Asia), and North Africa.
The influence of the Roman Empire on civilization is indelible. Numerous contributions in law, engineering, architecture, and other areas that promoted the growth of the towns derive from this. But above all, the Roman Empire is responsible for having connected the ancient world through the use of Latin and the construction of a common culture.
Political organization. The Roman Empire was based on a centralized power system in the figure of the emperor, empowered to legislate, command the army, and preside over religion. The emperor had an advisory body, called the senate, and an institution representing the Roman people called the assembly or comitia. The latter had little influence in the High Empire period and ceased to convene in the Lower Empire.
Military organization. The army was made up of legions. Each legion was divided into cohorts and these into centuries. There came to be thirty legions of 5,300 men each. The provincial governor commended the local units, under the direction of the Emperor. The ranks were distributed as follows:
Social organization. Society was hierarchical. The family was patriarchal. This means that the father exercised the ultimate authority over finances and children, regardless of his marital status. On the other hand, the social classes were framed in two groups: 1) citizens (patricians, equities, and plebeians); 2) non-citizens (slaves and freedmen).
Economy. The State intervened in the economy and had a tax system. There was currency circulation (sestertius, denarius), which facilitated economic integration. Trade was encouraged by the Empire's road network. Economic growth allowed for the division of labor.
Religion. Until the fourth century, the religion of the Roman Empire was paganism. Along with this, the Romans had the habit of absorbing the pantheon of gods of the conquered peoples. In the year 313 the Christianization of Rome began, until the definitive officialization of Christianity in the year 380.
Culture. The Roman Empire stood out for being cosmopolitan and open to the knowledge of foreign peoples, which allowed great innovations. Along with this, it promoted the construction of a common culture in all its domains, facilitated by its public works of engineering and architecture (aqueducts, baths, theaters, amphitheaters, circuses, etc.), Latin art, and literature.
Extension of the Roman Empire. The Empire came to encompass the Middle East, North Africa, and much of Europe. Its maximum extension was reached in the second century AD The occupied territory would correspond to 47 current countries. Namely:
Expansion of Rome, from the founding of the Republic to the fall of the Western Roman Empire.
The history of the Roman Empire can be studied according to its stages. These stages are the High Roman Empire (27 BC-284 AD) and the Low Roman Empire (284-476 AD). But to understand them, we must first look at their background.
Vincenzo Camuccini: The Death of Julius Caesar. 1804-1805.
The Roman Empire has its antecedents in the Republic of Rome. Shortly before being assassinated, Julius Caesar had been appointed dictator for the life of Rome (year 44 BC). Given the power vacuum, a triumvirate was formed made up of Marco Emilio Lépido, Marco Antonio, and César Octavio, his great-nephew and adopted son. But the triumvirate dissolved in 42 BC, leading to a war between Octavian and Mark Antony.
In the year 31 BC, Octavio defeated Marco Antonio and Cleopatra in the battle of Accio. A year later Marco Antonio won the battle of Alexandria, but the military desertion left him exposed, and Octavio achieved the annexation of Ptolemaic Egypt.
Both the Senate and the people hailed Octavian as First Citizen and Augustus in 27 BC The Senate gave him the authority to appoint their senators and governors. Later, Octavian Augustus established dynastic succession, all of which signal the start of the imperial age.
The High Roman Empire spans from 27 BC to 284 AD When Octavian was appointed Augustus, he began a collegiate monarchy called the Principate. The princeps (Octavio Augusto) concentrated the titles of princeps civium (first citizen), princeps senatus (president of the senate), and Imperator (victorious general).

Octavio Augusto, the first emperor of the Julio-Claudian dynasty, protected the borders and invested great resources in new constructions.
Thus began a period of political, economic, and social stability that became known as the Pax Romana or Pax Augusta, which lasted for two centuries. He was succeeded in power by Tiberius, Caligula, Claudius, and Nero, all from the Julio-Claudian dynasty.
On Nero's death in AD 68, a period of crisis called The Year of the Four Emperors ensued, referring to the reigns of Galba, Otto, Vitellius, and Vespasian. Only the latter achieved stability by rising to power in the year 69.
Founder of the Flavian dynasty, Vespasian promoted imperial prosperity and projects of great importance to the city, such as the construction of the Roman Colosseum. The successors of his dynasty were Titus and Domitian. The latter was assassinated by the Senate.
The Flavian dynasty was deposed by the Antonine dynasty. The expansion of the Roman Empire reached its peak in this period, also marked by increased prosperity.
During the Antonine dynasty, the so-called five good emperors stood out, namely: Nerca, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius. The latter was co-emperor with Lucius Verus, but Lucius Verus was a negligent emperor, as was Commodus, the last Antonine monarch.
Then another year of civil wars was generated again, which had five emperors. With the final accession of Septimus Severus, the Severan dynasty was established.
Severus extended the empire, but his conquests were very costly. He was succeeded by his sons Caracalla and Geta. The latter was named co-emperor by his father but ended up assassinated by his brother.
After a brief interruption, Elagabalus rose to power. He was succeeded by Alexander Severus, responsible for the Crisis of the Third Century that caused the civil war for control of Rome.
The Low Roman Empire covers from the year 284 to 476. This stage begins with the government of Diocletian, who instead of princeps, preferred the position of dominus (master and lord). The resulting governance model is known as Dominated.
The dominated consisted of the concentration of power in the hands of an absolute monarch, ignoring the authority of the institutions inherited from the republic and the High Empire.
In green: Western Roman Empire. In the pink: Eastern Roman Empire.
Over time, the political-economic center shifted to the East, and the borders began to come under attack. To respond, in the year 296 Diocletian divided the territory into two: the Eastern Roman Empire and the Western Roman Empire, each ruled by an emperor or Augustus.
To avoid conflict, Diocletian determined that each emperor appoints a successor from the beginning of the mandate. These successors would bear the title of Caesar and share the administration of the territory. It was thus that Diocletian instituted a tetrarchy. Power was organized and distributed as indicated in the following table:

In the year 303, Diocletian began the so-called Great Persecution against Christians, the bloodiest until then. Diocletian abdicated his office peacefully in 305 and made Maximian abdicate as well. Despite this, the persecution against Christians continued.
The Caesars Galerius and Constantius Chlorus were promoted to Augustus, and Severus II and Maximin Daya were appointed Caesars. But on the death of Constantius Chlorus, tensions would begin between Constantine I, his son, and Maxentius, son of Maximian.
On July 28, 312, the Battle of the Milvian Bridge took place, in which Constantine I the Great defeated Maxentius. With the triumph, Constantine secured himself as emperor and began his conversion to Christianity.

In the year 313, Constantine promulgated the Edict of Milan, in which he decreed religious toleration for Christianity. He also promoted a series of councils designed to unify Christian doctrine. Later, in the year 330, Constantine would establish the capital of the Empire in Byzantium and call it Constantinople (current Istanbul, in Turkey).
After several successions, Theodosius I the Great came to power. In 380, he promulgated the Edict of Thessalonica, in which he made Christianity official as the imperial religion and outlawed paganism.
On the death of Theodosius in 395, the Empire was divided. The West remained in the hands of Flavius Honorius, the youngest son of Theodosius. Oriente was left in the hands of Arcadio, his eldest son. But while the eastern wing of the empire prospered, the west declined.
Throughout the 5th century, the Western Roman Empire began to be undermined by barbarian invasions, also called Germanic migrations.
Finally, the emperor Romulus Augustulus was overthrown by the Germanic Odoacer in the year 476, who adopted the title of King of Italy. This represents the final fall of the Western Roman Empire.
Although the East perceived itself as the last bastion of the Roman Empire, it was losing control over the western territory, and it was outlined as the Byzantine Empire. This would only come to an end in the year 1453 after the Ottoman invasion.
