Alexander IV, born in 323 BC, was the son of the famous conqueror Alexander the Great and his wife, Roxana. He is a largely tragic figure in ancient history, remembered as a child who inherited an empire he never got to rule. Alexander IV’s short life was filled with political intrigue, power struggles, and his untimely death symbolized the end of the dream for a united empire created by his father.
Birth and Early Life
Alexander IV was born in 323 BC, in the ancient city of Babylon, only a few months after the death of his father, Alexander the Great. His mother, Roxana, was a princess from Bactria, a region in modern-day Afghanistan. The birth of Alexander IV came at a time when the empire, built through his father’s conquests, stretched from Greece to Egypt and as far east as India.
From the moment he was born, Alexander IV’s life was one of immense political importance. Being the only son of Alexander the Great, he was seen by many as the legitimate heir to the vast empire his father had built. However, because of his young age, the actual control of the empire fell into the hands of regents and generals, sparking intense political struggles over who would truly wield power.
The Power Struggles Following Alexander the Great’s Death
Alexander the Great’s sudden death at the age of 32 left a massive power vacuum. His empire, though large, was held together by his personal leadership and military genius. Without him, the question of succession became urgent. Although Alexander IV was the legitimate heir, he was only an infant and could not rule. As a result, the empire was left in the hands of Alexander’s generals, known as the Diadochi, who were tasked with ruling as regents until the young Alexander could assume power.
At first, Alexander IV was recognized as co-king alongside his uncle, Philip III Arrhidaeus, the half-brother of Alexander the Great. Philip III had developmental challenges, making him largely a figurehead, while the real power lay with the regents, particularly Perdiccas, one of Alexander the Great’s most trusted generals.
However, this arrangement was far from stable. The Diadochi quickly began to fight amongst themselves for control of different parts of the empire. What followed was a series of wars, known as the Wars of the Diadochi, in which Alexander the Great’s former generals fought to carve out their own independent kingdoms.

Regency and Guardianship
Initially, Perdiccas was appointed as the regent to oversee the empire in the name of Alexander IV and Philip III. However, his leadership was short-lived, as he was assassinated by his own officers in 321 BC. After Perdiccas’ death, the regency passed to Antipater, another of Alexander the Great’s generals, who took control of the western parts of the empire, including Greece and Macedonia.
Antipater, however, died in 319 BC, which reignited the power struggle for control over the empire. His successor, Polyperchon, sought to rule as regent, but he faced opposition from another powerful general, Cassander, the son of Antipater.
During these turbulent years, Alexander IV and his mother, Roxana, were moved around various territories for their protection. Roxana, fiercely protective of her son’s claim to the throne, aligned herself with whichever faction she believed could best secure Alexander IV’s future as the rightful king. However, as the power struggles intensified, the young Alexander IV became less a future ruler and more a pawn in the ongoing political games of the Diadochi.
The Fall of Alexander IV’s Hopes
By 316 BC, Cassander emerged as one of the most powerful figures in Macedonia. After defeating Polyperchon, he captured Roxana and Alexander IV and imprisoned them in the fortress of Amphipolis. While officially, Cassander continued to recognize Alexander IV’s claim to the throne, his actions were driven by his desire for personal control over Macedonia and Greece.
Cassander’s rule was a clear sign that Alexander IV’s position was becoming increasingly precarious. As the years passed, it became evident that the boy would never truly assume power. Cassander’s ambitions were to rule without opposition, and as long as Alexander IV lived, there was a threat to his rule. By 310 BC, Cassander decided to eliminate this threat.
The Death of Alexander IV
In 310 BC, when Alexander IV was about 13 years old, he and his mother Roxana were secretly murdered on the orders of Cassander. Their deaths marked the end of the Argead dynasty, the royal family that had ruled Macedonia since the time of Alexander the Great’s father, Philip II. With the death of Alexander IV, the hope of a unified empire under the legacy of Alexander the Great came to an end.
The murder of Alexander IV was a cold, calculated political move by Cassander. Without a legitimate heir to challenge him, he could fully consolidate his control over Macedonia and Greece. Although the empire had already fragmented by this point, Alexander IV’s death symbolized the final dissolution of any dream that the vast territories conquered by Alexander the Great could remain united.
Legacy of Alexander IV
Though Alexander IV never had the opportunity to rule, his life represents the fragile nature of dynastic succession in the ancient world. His brief existence was marked by immense potential that was never realized. Alexander IV’s death not only signaled the end of the Macedonian royal line but also underscored the fact that the empire his father had built was too vast and diverse to be governed by a single ruler after Alexander the Great’s death.
The Wars of the Diadochi that followed Alexander the Great’s passing were rooted in the inability of the empire to maintain unity. By the time Alexander IV was murdered, the empire had already been divided into various Hellenistic kingdoms, with Ptolemaic Egypt, Seleucid Asia, and Antigonid Macedonia emerging as major powers. These Hellenistic states continued to carry the cultural and military influence of Alexander the Great’s conquests, but the unified empire was lost forever.
Key Figures During Alexander IV’s Life
- Roxana: Alexander IV’s mother, a Bactrian princess who fiercely defended her son’s claim to the throne.
- Perdiccas: The first regent after Alexander the Great’s death, who tried to maintain the unity of the empire in the name of Alexander IV.
- Antipater: A powerful general who succeeded Perdiccas as regent and ruled the western portions of the empire.
- Cassander: The general who ultimately seized power in Macedonia, imprisoned Alexander IV, and ordered his assassination.
- Philip III Arrhidaeus: Alexander the Great’s half-brother and co-king with Alexander IV, though he had limited political influence due to his mental condition.
A Life of Unfulfilled Potential
Alexander IV’s story is a poignant reminder of the volatility of power in the ancient world. Born into the most powerful family of his time, he was, in many ways, a symbol of hope for those who wanted to see Alexander the Great’s empire continue under his son’s rule. However, his fate was ultimately sealed by the ambitions and rivalries of the Diadochi, who prioritized their own power over the legacy of the boy king.
Though his life was short and his rule never materialized, Alexander IV remains a significant figure in ancient history, representing the end of the Macedonian dynasty and the final dissolution of the empire that once stretched across three continents.
