 were not convinced. Octavian’s chance came when Antony married Cleopatra in 32 BC before he divorced Octavia. That action combined with information that Antony was planning to establish a second Senate in Alexandria created the perfect environment for Octavian to strip Antony of his power.

. In it, Antony recognized Caesarion as Caesar's legal heir, left his possessions to his children by Cleopatra, and finally indicated his desire to be buried with Cleopatra in Alexandria instead of in Rome. The Senators were not moved by Caesarion or Antony’s children but Antony’s desire to be buried outside of Rome invoked the Senate’s rage. Octavian, the natural politician he was, blamed Cleopatra and not Antony. The Senate declared war on Cleopatra, and Octavian knew that Antony would come to her aid.

When Cleopatra received word that Rome had declared war, Antony threw his support to Egypt. Immediately, the Senate stripped Antony of all his official power and labeled him as an outlaw and a traitor. Octavian summoned all of his legions, numbered at almost 200,000 Roman legionaries. Cleopatra and Antony did the same, assembling roughly the same number in mixed heavy Roman and light Egyptian infantry.

Naval theater

By mid-summer of 31 BC, Antony maneuvered his army into Greece and Octavian soon followed. Octavian brought with him his chief military advisor and closest friend Marcus Vipsanius Agrippa

 to command his naval forces. Although the ground forces were comparable, Octavian's fleet was superior. Antony's fleet was made up of large vessels, but with inexperienced crews and commanders. Octavian's fleet of smaller, more maneuverable vessels was filled with experienced sailors.

 and put it to flight, but when the latter was reinforced by Marcus Agrippa, Sosius's ally Tarcondimotus - the king of Cilicia - was killed and Sosius himself was forced to flee.

Octavian decided not to attack and risk unnecessary losses. Instead, Octavian wanted to battle Antony by sea where his experienced sailors could dominate. In response, Antony and Octavian engaged in Fabian strategy

s through the strait and into the open sea. There, Octavian’s light and maneuverable Liburnian ships drew in battle formation against Antony’s warships. Cleopatra stayed behind Antony’s line on her royal barge.

A devastating blow to Antony’s forces came when one of Antony’s former generals delivered to Octavian Antony’s battle plan. Antony had hoped to use his biggest ships to drive back Agrippa's wing on the north end of his line, but Octavian's entire fleet stayed carefully out of range. Shortly after mid-day, Antony was forced to extend his line out from the protection of the shore, and then finally engage the enemy. Octavian's fleet, armed with better trained and fresher crews, made quick work of Antony’s larger and less experienced navy. Octavian’s soldiers had spent years fighting in Roman naval combat, where one objective was to ram the enemy ship and at the same time kill the above deck crew with a shower of arrows and catapult-launched stones large enough to decapitate a man.

As the armies stood on either side of the naval battle, they watched as Antony was being outmatched by Agrippa. Seeing that the battle was going against Antony, Cleopatra's fleet retreated to open sea without firing a shot, leaving Antony to fight for himself. As a gap opened in Agrippa's blockade, she funneled through, and was soon closely followed by Antony's command ships. The commanders of Antony's land forces, which were supposed to follow him to Asia, promptly surrendered their legions without a fight. Antony retreated to a smaller vessel with his flag and managed to escape to Alexandria. By the end of the day, Antony’s entire fleet would lie at the bottom of the sea and the Roman world had witnessed the largest naval battle in almost 200 years.

Land campaign

With Octavian now in control of nearly 60 legions (approximately 360,000 men), he was left as the indisputable master of the Roman world. Although Octavian wanted to immediately pursue Antony and Cleopatra, many of his veterans wanted to retire and return to private life. Octavian allowed many of his longest serving veterans (as many as 10 legions by some accounts) to retire. Many of those legionaries could trace their service to Julius Caesar

 some 20 years earlier.

After the winter ended, Octavian resumed the hunt. In the spring of 30 BC, Octavian rejected the idea of transporting his army across the sea and attacking Alexandria directly, and instead traveled by land through Asia. Antony had received much of his backing from Rome’s client kingdoms in the east. By marching his army by land, he ensured Antony could not regroup and cement his authority over the provinces.

Meanwhile, Antony attempted to secure an army in Cyrenaica

. Unfortunately for Antony, Pinarius had switched his loyalty to Octavian. When Octavian received word of this development, he ordered Pinarius to move his four legions east towards Alexandria while Octavian would move west. Trapped in Egypt with the remnant of his former army, Antony and Cleopatra bided their time awaiting Octavian's arrival.

When Octavian and Pinarius arrived at Alexandria, they placed the entire city under siege. Before Octavian had arrived, Antony took the roughly 10,000 soldiers he had left and attacked Pinarius, unaware that he was outnumbered 2 to 1. Pinarius destroyed what was left of Antony’s army with Antony escaping back to Alexandria before Octavian arrived. As Octavian approached with his legions, what remained of Antony's cavalry and fleet surrendered to Octavian. Most of Antony’s infantry surrendered without any engagement at this stage of the conflict, they were Italian veterans and Antony's cause was lost.

Antony was forced to watch as his army and hopes of dominance in Rome were handed to Octavian. In honorable Roman tradition, Antony, on August 1, 30 BC, fell on his sword. According to the ancients accounts however, he was not entirely successful and with an open wound in his belly, was taken to join Cleopatra, who had fled to her mausoleum

Cleopatra did not immediately follow Antony in suicide. Instead, in a last ditch effort, Cleopatra opened negotiations with Octavian. Cleopatra begged Octavian to spare Caesarion

Aftermath

Within a month, Octavian was named Pharaoh, and Egypt became his personal possession. With Octavian in control of all of Rome's provinces and over 50 legions, he was now the undisputed master of the Roman world. Through executing Antony's supporters, Octavian finally brought a century of civil war to a close. Within a few years, Octavian was named Augustus

.

In the ensuing months and years, Augustus passed the series of laws that while outwardly preserving the appearance of the Republic made his position within it of paramount power and authority. He laid the foundations for what is now called the Roman Empire. From then on, the Roman state would be ruled by a Princeps (first citizen), in modern terms, Rome would from now on be ruled by Emperors. The Senate ostensibly still had power and authority over certain Senatorial provinces, however, the critical border provinces, like Syria, Egypt, Gaul, requiring the greatest numbers of legions would be directly ruled by Augustus and the Emperors who succeeded him.

With the end of the last Republican civil war, the Republic was replaced by the Empire. Augustus's reign would usher in a golden era of Roman culture and produce a stability that Rome had not seen in over a century. With Rome in control of the entire Mediterranean world, a peace that would reign in the Roman world for centuries after Augustus’s death: the Pax Romana
