5 min read•Last Updated on August 13, 2024
The fourth century BCE marked a pivotal shift in ancient Greece. As traditional city-states like Athens and Sparta declined, Macedon rose to power under Philip II. This period saw major political changes, with Philip's conquest of Greece ending the era of independent poleis.
Socially and economically, Greece transformed too. Mercenary armies replaced citizen militias, trade expanded, and new philosophical schools emerged. These changes set the stage for Alexander the Great's conquests and the dawn of the Hellenistic era.

1 of 3
The fourth century BCE witnessed a shift in the balance of power in the Greek world, with the decline of traditional city-states like Athens and Sparta and the rise of Macedon under Philip II
The Peloponnesian War (431-404 BCE) weakened the major Greek city-states (Athens and Sparta), creating a power vacuum that allowed the rise of new powers like Thebes and eventually Macedon
Philip II's Expansion of Macedonian Influence
Philip II of Macedon exploited the weakened city-states, using military force, diplomacy, and bribery to expand Macedonian influence and control over Greece
The Battle of Chaeronea in 338 BCE, where Philip II defeated a coalition of Greek city-states led by Athens and Thebes, effectively marked the end of the era of independent city-states and the beginning of Macedonian hegemony
Philip II formed the League of Corinth in 337 BCE, which brought the Greek city-states under Macedonian control and paved the way for Alexander the Great's eventual conquest of the Persian Empire
Social and Economic Changes in Greece
Shift Towards Mercenary Armies
The fourth century BCE brought significant social and economic changes in the Greek world, partly driven by the political upheavals of the period
The decline of the traditional city-state model led to a shift away from citizen militias and towards the use of professional, mercenary armies, which became increasingly important in the conflicts of the period
Expansion of Trade and Economic Complexity
The rise of Macedon and Alexander the Great's conquests opened up new trade routes and markets, leading to an increase in long-distance trade and the growth of a more complex, interconnected economy
The influx of wealth from conquest and trade led to the rise of a new class of wealthy elites, who often used their resources to fund public works, patronize the arts, and engage in conspicuous consumption (lavish banquets, expensive clothing)
Emergence of New Social and Philosophical Movements
The fourth century BCE saw the emergence of new social and philosophical movements, such as the Cynics and the Epicureans, which challenged traditional Greek values and ways of life
These movements questioned conventional notions of virtue, happiness, and the role of the individual in society, contributing to a more diverse and dynamic intellectual landscape
Influence of Philosophical Schools
Plato's Academy
The fourth century BCE was a golden age of Greek philosophy, with the establishment of major philosophical schools that would influence Western thought for centuries to come
Plato, a student of Socrates, founded the Academy in Athens around 387 BCE, which became a center of philosophical and scientific study and attracted scholars from across the Greek world
The Academy emphasized the study of mathematics, astronomy, and metaphysics, and its curriculum was based on Plato's theory of Forms
Notable students of the Academy included Aristotle, who would go on to found his own school, the Lyceum
Aristotle's Lyceum
Aristotle established the Lyceum in Athens around 335 BCE, which became a major center of scientific and philosophical study
The Lyceum emphasized empirical observation and the study of the natural world, and its curriculum was based on Aristotle's works on logic, biology, physics, and metaphysics
The Lyceum attracted students from across the Greek world and beyond, and its influence can be seen in the works of later philosophers (Theophrastus, Strato)
Impact on Greek Intellectual Life
The philosophical debates and innovations of the fourth century BCE had a profound impact on Greek intellectual life, shaping the development of fields such as ethics, politics, and natural philosophy
The ideas and methods developed in the Academy and Lyceum would continue to influence philosophical and scientific thought for centuries, laying the foundation for the Hellenistic period and beyond
Significance of Philip II's Reign
Transformation of Macedon
Philip II of Macedon (r. 359-336 BCE) was a pivotal figure in Greek history whose reign set the stage for the conquests of his son, Alexander the Great
Philip II transformed Macedon from a relatively minor kingdom into a major power through a combination of military reforms, diplomatic maneuvering, and strategic conquests
He reorganized the Macedonian army, introducing the sarissa (a long pike) and the cavalry as key elements of his military strategy
He used diplomacy and bribery to gain influence over the Greek city-states, particularly in the aftermath of the Third Sacred War (356-346 BCE)
Establishment of Macedonian Hegemony
Philip's victory over the Greek city-states at the Battle of Chaeronea in 338 BCE effectively ended the era of the independent city-state and established Macedonian hegemony over Greece
The League of Corinth, formed by Philip in 337 BCE, brought the Greek city-states under Macedonian control and provided a platform for the planned invasion of the Persian Empire
Although Philip was assassinated before he could launch the invasion, his son Alexander was able to use the resources and alliances created by his father to carry out his legendary conquests (Persian Empire, Egypt, India)
Legacy and Impact
Philip's reign marked a turning point in Greek history, as the center of power shifted from the city-states to the Macedonian monarchy, setting the stage for the Hellenistic period that would follow Alexander's conquests
The military, political, and diplomatic innovations introduced by Philip II laid the foundation for the creation of a vast Hellenistic world, which would spread Greek culture and influence across the Mediterranean and beyond
