The Time of Alexander (Leaving Cert Classical Studies): Revision Notes
The Time of Alexander
Historical background of the late classical period
Understanding Alexander's rise requires examining the turbulent world he inherited. The Greek world of the 4th century BC was marked by warfare, political upheaval, and shifting power dynamics that created the perfect conditions for Macedonian expansion.
The late classical period (roughly 4th century BC) was a time of transition when the traditional Greek city-state system was breaking down, creating opportunities for new forms of political organisation and imperial expansion.
The weakening of Greek city-states
The Peloponnesian War (431-404 BC) between Athens and Sparta devastated the Greek world. This prolonged conflict drained resources, destroyed alliances, and left all Greek city-states significantly weakened. The war's aftermath created a power vacuum that Macedonia would eventually fill.

The traditional Greek city-state system (poleis) struggled to maintain independence and stability after decades of warfare. Rivalries between major powers like Athens, Thebes, and Sparta continued to create instability throughout the Greek world.
The Peloponnesian War was not just another conflict - it fundamentally transformed the Greek world by exhausting the resources and manpower of all participants, making them vulnerable to outside conquest for the first time in centuries.
Philip II's transformation of Macedonia

Philip II (359-336 BC) revolutionised Macedonia and set the stage for his son's future conquests. His key achievements included:
- Military innovation: Philip reorganised the Macedonian army, introducing the famous sarissa phalanx - a formation using extremely long spears that proved devastatingly effective against traditional Greek warfare
- Political expansion: He systematically expanded Macedonian influence throughout Greece, using both diplomacy and military force
- Decisive victory: At the Battle of Chaeronea (338 BC), Philip defeated Athens and Thebes, effectively ending Greek independence
As Plutarch noted: "Philip left Alexander a kingdom not small, but great enough for him to exercise his abilities."
The League of Corinth and succession
In 337 BC, Philip established the League of Corinth, uniting Greek states (except Sparta) under Macedonian leadership. This league was ostensibly created to organise a campaign against Persia, but in reality, it secured Macedonian control over Greece.
Philip's assassination in 336 BC brought Alexander to the throne at just 20 years old, inheriting both tremendous opportunities and significant challenges. The timing was crucial - any delay might have allowed Greek resistance to reorganise.
Political tensions and challenges
When Alexander became king, he faced a complex web of political problems that threatened to destabilise his inheritance before he could even begin his famous conquests.
Greek resistance to Macedonian rule
Greek disunity remained a persistent problem. The city-states had never willingly accepted Macedonian dominance, and many harboured deep anti-Macedonian sentiment following their defeat at Chaeronea. This resentment created ongoing instability throughout Alexander's reign.
Fragile loyalty characterised many relationships with Greek states. Some cities tested the young king's authority immediately after his succession - Thebes rebelled in 335 BC but was quickly and brutally crushed by Alexander, serving as a warning to other potential rebels.
Alexander's destruction of Thebes in 335 BC was a calculated political move. By making an example of one rebellious city, he demonstrated his military capability and deterred other potential revolts, allowing him to focus on his Persian campaigns.
Internal Macedonian politics
Macedonian court intrigues posed another serious threat. Philip's assassination had left uncertainty about succession, and Alexander needed to secure the loyalty of nobles and the army. The royal court was notorious for its political scheming and personal rivalries.
As Arrian observed: "The Greeks were restless under Macedonian rule, but Alexander struck fear into their hearts by the swiftness of his campaigns."
The Persian opportunity
The Persian Empire still controlled vast territories from Asia Minor to Egypt and Mesopotamia, but it was weakened by internal revolts and leadership crises under Darius III. This weakness presented Alexander with both a threat (Persia still influenced Greek politics) and a tremendous opportunity for conquest.
Geographical transformation
Alexander's conquests created the first truly multi-continental empire in history, fundamentally changing the political geography of the ancient world.
Before Alexander's conquests (c. 336 BC)
The ancient world was politically fragmented:
- Greece: Divided into numerous independent city-states, often hostile to each other
- Macedonia: Rising power under Philip II, controlling northern Greece
- Persian Empire: Vast but decentralised empire stretching from Asia Minor to Egypt and Mesopotamia, showing signs of internal weakness
The fragmented nature of the ancient world before Alexander meant that cultural and economic exchange between regions was limited, despite some trade connections. No single power had successfully united such diverse territories under one rule.
After Alexander's conquests (c. 323 BC)
Alexander's campaigns created an unprecedented unified empire:
- Territorial extent: The empire stretched from Greece to Egypt, across Persia, and as far as the Indus Valley in India
- Unity through conquest: For the first time, diverse regions were brought under single military and political control
- Cultural fusion: Greek, Persian, Egyptian, and other cultures began to interact on an unprecedented scale

However, this unity proved fragile. As Plutarch noted: "His empire was boundless, yet his ambition was greater still." After Alexander's death, the empire was divided amongst his generals (the Diadochi), ending the brief period of unified control.
Alexander's empire was remarkable not just for its size, but for its cultural diversity. Managing such varied peoples, languages, and traditions required innovative approaches to governance that influenced imperial administration for centuries to come.
Key themes for understanding
Several important themes emerge from studying Alexander's time:
- Ambition vs. reality: Alexander inherited great power but also faced enormous challenges
- Unity vs. disunity: The contrast between fragmented Greek city-states and Alexander's unified empire
- Opportunity from weakness: Persia's decline created the conditions for Macedonian expansion
- Legacy and fragility: Alexander's empire was both historically significant and ultimately unsustainable
Key Points to Remember:
- The Peloponnesian War weakened all Greek city-states, creating opportunities for Philip II's expansion
- Philip II's military and political innovations, especially the sarissa phalanx and League of Corinth, laid the foundation for Alexander's success
- Alexander inherited both tremendous power and serious challenges, including Greek resistance and court intrigue
- The Persian Empire's weakness provided the perfect opportunity for Alexander's eastern conquests
- Alexander created the first multi-continental empire, stretching from Greece to India, though it fragmented after his death
