How did Emperor Augustus usher in Pax Romana?

Origins of Pax Romana

“I found Rome a city of bricks, and left it a city of marble.” (Marmoream se relinquere, quam latericiam accepisset”).

So goes one of the last things Roman Emperor Augustus said before his death in 14 AD.

More than 40 years prior, Augustus rose to power and provided Rome a way out of its political and economic problems, making himself the first Emperor of Rome.

The statement highlights Augustus’s significant contributions to the architectural development of Rome during his reign, which ushered a period called Pax Romana.

Pax Romana, which means “Roman peace” in Latin, refers to a period of relative peace, stability, and order that existed in the Roman Empire from approximately 27 BCE to 180 AD.

The almost two-century period is often associated with the reign of Emperor Augustus and the early years of the Roman Empire.

However, it should be noted that the Pax Romana, which has often been called as Rome’s Golden Age, was not a complete absence of conflict but rather a period characterized by a general reduction in large-scale wars and internal strife.

One thing is for certain: Rome’s first emperor, Augustus, played a crucial role in establishing and maintaining the Pax Romana, a two-century period of relative peace, order, and stability in the Roman Empire.

Here are some key ways in which Augustus contributed to the Pax Romana:

First, he consolidated his power

Augustus’s 41-year reign as emperor was praised for the sheer amount of transformation he made. It also made him the second longest-reigning Roman Emperor in history, only behind Theodosius II of the Eastern Roman Empire who reigned for 42 years, from 408 to 450 AD.

After a long period of civil wars and political instability, Augustus emerged as the sole ruler of Rome in 27 BC. This came in the aftermath of his famous victory over his fiercest rival and former triumvir (of the Second Triumvirate) Mark Antony around 30 BC. At the battle of Actium, Octavian handed the alliance of Mark Antony and his mistress, Egyptian Queen Cleopatra VII, a resounding defeat, which resulted in Antony and Cleopatra committing suicide.

Octavian then proceeded to skillfully cement his power by restoring the outward appearance of the Roman Republic while holding ultimate authority as the princeps, or first citizen.

His elevation meant that the power of the Senate was reduced, transforming Rome from a Republic to an empire with emperors.

By establishing a stable and centralized government, he laid the foundation for the Pax Romana.

Augustus’s military reforms sets Rome on the path of never-before-seen greatness

Augustus undertook significant military reforms to strengthen the Roman legions. He reduced the number of legions, increased their pay, and established a standing army.

As emperor, Augustus made sure that Roman soldiers were rewarded to the extent that their loyalty was to the empire and not their commanders. This professionalized military structure ensured the empire’s defense and deterred external threats, contributing to the peace and stability of the Pax Romana.

The military reforms also made it possible for to stretch the empire’s borders into places in central Europe and present-day Israel.

When things looked dire, he resorted to diplomacy in order to expand Rome’s influence

Augustus pursued a policy of diplomacy and cautious expansion. He focused on securing the empire’s borders rather than engaging in aggressive conquests. Through diplomacy, he formed alliances, negotiated treaties, and established client kingdoms, which helped to maintain peaceful relations with neighboring regions and reduced the risk of conflicts.

In effect, Augustus branded the growing empire as the most civilized in the region. This enabled him to assimilate foreign lands and enemies with little to no resistance. Basically, the allure of Roman citizenship and its associated advantages enticed many to embrace Roman identity.

And those that insisted on keeping their identities, Augustus did not have any problem with them so long as they stayed loyal to the empire.

Introduced a number of administrative reforms

Augustus reformed the administration of the Roman Empire, streamlining the bureaucracy and establishing a more efficient system. He appointed capable governors and officials, reorganized provinces, and implemented a system of taxation and governance that reduced corruption and improved the administration of justice. This contributed to stability and effective governance throughout the empire.

For example, under Augustus’s reign, a salaried civil service was instituted to enforce laws, manage tax collection, and govern with increased efficiency. This shift of power from the nobility to a bureaucratic system allowed for a more organized and streamlined administration.

In addition to those notable administrative initiatives, he introduced a census to ensure equitable taxation by assigning fixed quotas for each Roman province.

His reign, also saw the establishment of a postal service, a dedicated police force, and a fire brigade to enhance public safety and security.

One of his significant creations was the Praetorian Guard, initially conceived as his personal bodyguard, which later evolved into a fierce political force and an imperial guard that carried a number of assassinations.

Infrastructure Development

Augustus invested in extensive infrastructure projects across the empire. He improved road networks, constructed aqueducts, and developed public buildings. These projects not only facilitated trade and communication but also provided employment opportunities, contributing to economic stability and social welfare.

For example, it’s been stated that during Augustus’s reign, more than 45,000 miles of new roads were constructed. Not only did those infrastructure projects enhance the economic fortunes, they also allowed Augustus’s Roman army to march unimpeded.

Aqueduct of Segovia (in present-day Spain) was built around the first century AD, probably during the the reigns of the Emperors Domitian, Nerva, and Trajan. In 1985, the Old Town of Segovia and the aqueduct, were declared a UNESCO World Heritage Site.

Cultural Patronage

Augustus was a generous patron of the arts and literature. He supported poets, writers, and artists, encouraging the flourishing of Roman culture. This cultural patronage created an environment of intellectual and artistic development, fostering a sense of shared identity and contributing to the overall stability and prosperity of the empire.

Some of the notable poets and scholars that flourished during Augustus’s reign were Virgil (70 BC – 19 BC) and Livy (59 BC – 17 AD). The former is famed for his work the Aeneid, an epic poem that describes the legendary Trojan War as well as how Rome came to being.

Propagation of Roman Values

As part of his quest to cement the gains he had chalked in the political and military spheres of Rome, Augustus promoted traditional Roman virtues and values, emphasizing family, morality, and civic duty. He encouraged marriage, family life, and childbearing through legislation and social policies. This focus on social stability and the reinforcement of Roman cultural norms played a significant role in maintaining internal harmony during the Pax Romana.

There is no doubt that the above programs initiated by Emperor Augustus laid the groundwork for a relatively prosperous and peaceful Rome – a Rome that his successors like Emperor Trajan (reign: 98-117 AD), Hadrian (reign: 117-138 AD), and Marcus Aurelius (reign: 161-180 AD) would build upon and make it one of the greatest empires in world history.

Although the period was not entirely devoid of conflicts or internal issues, Augustus’s reforms and policies played a vital role in maintaining peace, order, and stability across the vast Roman Empire for two centuries.

How did Augustus rise to power?

Born Octavian, Augustus was the great uncle and later adoptive son/heir of the famed Roman general and dictator Julius Caesar.

Death of Julius Caesar

Realizing that he was not strong, politically and financially, enough to assert his claim to Rome, he went into an alliance with Roman generals Mark Antony (63 – 14 BC) and Marcus Aemilius Lepidus (C. 89 – 12 BC), thus forming the Second Triumvirate. The political alliance then went ahead to either kill or exile anyone that was involved in Caesar’s assassination. Basically, the Second Triumvirate, like the Caesar-led First Triumvirate, were in charge of the Roman Republic.

Octavian and Mark Antony

Both sides bear the inscription “III VIR R P C”, meaning “One of Three Men for the regulation of the Republic”.

And just like the First Triumvirate, the Octavian-Lepidus-Antony alliance fractured due to irreconcilable differences and immense rivalries.

In the end, Octavian came out the victor of the intense power struggle that ensued in the Republic. The final showdown took place between Octavian and Mark Antony, who was being backed by Queen Cleopatra of Egypt. Octavian forces defeated Antony and Cleopatra in the Battle of Actium in 31 BC.

Following his victory at Actium, he returned to Rome a beloved figure of both the people and Senate. In 27 BC, the latter conferred on him the title of Augustus and Princeps, which translate as ‘exalted one’ and ‘first among equals’, respectively.

Many of these structures and engineering techniques continued to be admired and emulated in later civilizations.

Also known as the golden age of the Roman Empire, Pax Romana was a period during which the Roman Empire’s influence, territorial control, and population growth reached its zenith.
