Cleopatra VII Philopator, the last ruler of the Ptolemaic Kingdom, was also Egypt’s last active Pharaoh. Cleopatra was not a direct descendant of Alexander the Great, but she was closely linked to the legendary conqueror through Ptolemy I Soter, one of Alexander’s most trusted generals and companions, who established the Ptolemaic dynasty. The Ptolemies ruled Egypt for three centuries, keeping their bloodline pure by marrying within family. However, like all Hellenistic kingdoms, the Ptolemaic Egypt could not rival the might of Rome. Cleopatra’s reign was marked by her strategic political alliances with two Rome’s most influential leaders – Julius Caesar and Mark Antony. However, Cleopatra’s attempts to keep the throne failed, leading to her suicide, with Egypt becoming a vital province of the Roman Empire.

Cleopatra VII Philopator, the iconic Queen of Egypt, was not a direct descendant of Alexander the Great. She was, however, the descendant of Ptolemy I Soter, one of Alexander’s most trusted generals and companions. Following Alexander’s death in 323 BCE, his generals and successors – diadochi – carved the vast empire, establishing powerful Hellenistic kingdoms. Ptolemy took over control of Egypt, establishing the Ptolemaic dynasty, which would rule over the region for three centuries. 


According to some sources, Ptolemy was son of Arsinoe and Phillip II, the father of Alexander the Great. However, this is likely a myth, fabricated to legitimize Ptolemy’s claim and bolster the prestige of his family, linking it to the Argead dynasty of Macedonia.

Cleopatra was a direct descendant of Ptolemy I Soter, who after Alexander’s death became ruler of Egypt, calling himself both a Hellenistic king (basileius) and a Pharaoh. She was born in 69 BCE to Ptolemy XII Auletes. While her mother identity is uncertain, it is widely believed that she was Cleopatra Tryphaena, Ptolemy’s wife. Cleopatra’s Greek heritage is well established, being a Greek Macedon royalty that avoided mixing with the locals. Ptolemaic kings and queens spent most of time in the capital of Alexandria, occasionally visiting hinterland to perform traditional ceremonies.


The rulers and the aristocracy, residing in the new cities, spoke Koine Greek, the lingua franca of the Hellenistic world and the language of the Ptolemaic court. Egyptian, on the other hand, was spoken by the common people and the priests. Cleopatra, however, could speak multiple languages, including Egyptian, unusual for a Ptolemaic ruler.

For centuries, Ptolemaic Egypt was a dominant Hellenistic kingdom, and a major power in the Eastern Mediterranean. However, by the time Cleopatra’s father took throne, Rome had emerged as a rival. The assassination of Pompey the Great, orchestrated by Cleopatra’s brother Ptolemy XIII, led to Rome’s direct involvement in Egypt’s affairs. Cleopatra swiftly jumped at the opportunity, establishing personal and political relationship with Julius Caesar, to eliminate her brother, and secure the throne. Following Caesar’s assassination in 44 BCE, Cleopatra aligned herself with Mark Antony, another influential Roman. 


Cleopatra’s alliance with Antony was both romantic relationship and strategic partnership, as the two sought to establish a strong Roman-Hellenistic state. However, their plans were thwarted by defeat at the Battle of Actium in 31 BCE by Octavian’s forces. In the aftermath, Cleopatra committed suicide, and with her death, and execution of her son Cesarion, the Ptolemaic Kingdom ceased to exist, becoming a province of the Roman Empire. 


Part of Alexander the Great’s Legacy

Although Cleopatra was not a direct descendant of Alexander the Great, her life and reign were deeply influenced by Alexander’s lasting legacy – the Hellenistic world. Alexander’s vast empire collapsed shortly after his death, in a series of bloody wars. Yet, the Hellenistic kings also engaged in diplomacy, trade and exchange of people, goods and ideas, shaping and unifying a vast area, from Eastern Mediterranean to the Himalayas. Ptolemaic Egypt, was a main center of Hellenistic culture, renowned for its cosmopolitan capital of Alexandria and the vibrant fusion of Greek and Egyptian traditions. 


Cleopatra herself was exceptional; she could speak multiple languages, including Egyptian, unusual for a Ptolemaic ruler. Her reign marked the culmination of the cultural and political legacy of Alexander the Great. When Cleopatra died, it signaled the end of the Hellenistic era. But not the end of Alexander’s legacy. The Roman Empire of Augustus could not resist the spell, becoming the inheritor of the Hellenistic world.
