In ancient Greece, timber was a strategic resource that could determine the strength of a navy and the political influence of a state. Athens used diplomacy to secure wood for its fleet in order to protect its territory, maintain its alliances, and exercise power across the Aegean Sea.
The Ancient Greek Kingdom of Macedon with its extensive forests, was an important source of the wood required for building and repairing warships. As a result, relations between Athens and the Macedonian kings were shaped by a common economic interest but also by competition for political and military influence.
In her article Athens and the Macedonian Kingdom from Perdikkas II to Philip II, historian Selene Psoma examines these relations from the perspective of both kingdoms. She argues that Macedonian opposition to Athens was often a response to Athenian attempts to control Macedonian resources and territory.
Psoma’s central purpose is to provide the Macedonian point of view and challenge the bias of ancient sources that were primarily Athenian. Her study shows that Athens used diplomacy, agreements, alliances, and settlements to obtain timber, but these methods could also create distrust and conflict.
The importance of Macedonian timber
The Athenian navy was the foundation of the city’s military power. The victory over the Persians at Salamis in 480 BC demonstrated the importance of warships to the survival of Athens. However, maintaining a large fleet required a constant supply of suitable timber. Macedonia possessed valuable forests, particularly those producing silver fir, which was especially suitable for shipbuilding.
Psoma explains that timber was a royal monopoly in the kingdom of Macedon. The king therefore exercised significant control over the supply of this important resource. Athens could not always obtain timber through ordinary commercial transactions without considering the political interests of the Macedonian ruler.
The earlier relationship between Athens and King Alexander I illustrates how diplomacy could help secure access to Macedonian resources. Psoma notes that Alexander I was an Athenian proxenos (consul) and euergetes (benefactor), terms associated with representing and benefiting the interests of another community. She suggests that his friendly relations with Athens may have been connected with the timber trade. The Athenian fleet that fought at Salamis had, in part, been built using Macedonian timber.
This example demonstrates that diplomatic friendship could produce practical benefits. Good relations with a foreign king could help Athens obtain materials essential to its security. However, such cooperation depended on the willingness of the Macedonian ruler to continue supplying them.
Perdikkas II and the limits of friendly relations
The reign of Perdikkas II, who ruled Macedonia from approximately 454 to 413 BC, reveals the difficulties involved in maintaining this relationship. At first, Athens and Macedonia had reasons to cooperate. Athens needed timber, while the Macedonian king could benefit from trade with a powerful maritime state.
Nevertheless, their interests gradually diverged. Athens wanted reliable access to Macedonian resources, but it also sought to expand its influence in the northern Aegean. The Macedonian king, meanwhile, wanted to preserve his authority and prevent Athens from gaining excessive control over neighboring territories.
Historian Konstantinos Karathanasis explores this conflict in his 2019 article, “A Game of Timber Monopoly: Atheno-Macedonian Relations on the Eve of the Peloponnesian War.” He argues that Perdikkas opposed Athenian expansion by restricting the supply of valuable shipbuilding timber. His study describes the king’s timber policy as a means of resisting Athenian imperialism.
This interpretation suggests that trade was also a diplomatic instrument. By controlling the export of timber, Perdikkas could put pressure on Athens and defend Macedonian interests. The Athenians, in turn, had to consider whether cooperation with the king would continue to serve their naval ambitions.
Amphipolis and the Athenian diplomatic strategy
The foundation of Amphipolis in 437 BC was an important development in the struggle for access to northern resources. Located near the River Strymon, Amphipolis gave Athens a strategic position in a region rich in timber and other valuable resources.
The settlement reduced Athenian dependence on the Macedonian king because it offered a potential alternative source of timber. At the same time, it strengthened Athenian influence in an area that mattered greatly to Macedonia.
Psoma explains that Athens repeatedly sought to establish a presence in the Strymon region. The capture of Eion in 476 BC and the later foundation of Amphipolis formed part of a broader effort to secure control over strategically important territories.
These developments reveal both the possibilities and the limits of diplomacy. Athens could negotiate with Macedonian rulers for timber, but it also attempted to secure resources by establishing its own settlements. Such policies might improve its bargaining position, yet they could also threaten the interests of the Macedonian kingdom.
From the Athenian perspective, gaining access to forests and trade routes was essential to maintaining naval strength. From the Macedonian perspective, the establishment of an Athenian settlement near its sphere of influence represented a potential threat. Consequently, the search for timber became inseparable from the struggle for regional power.
Alliances as a means of securing resources
One of the clearest examples of Athenian diplomatic strategy was its alliance with Philip, the brother of Perdikkas II, and Derdas, another opponent of the Macedonian king. Thucydides records the consequences of this decision in his History of the Peloponnesian War.
The ancient Greek historian explains that Perdikkas became an enemy of Athens because the Athenians had formed an alliance with Philip and Derdas, who were opposed to him. This move shows that Athenian diplomacy could undermine an existing relationship. Instead of relying exclusively on Perdikkas, Athens established connections with his rivals. Such an alliance could weaken the king’s position and potentially provide Athens with access to territories and resources beyond his direct control.
Karathanasis interprets this policy as part of an elaborate Athenian strategy. He argues that the alliance could help Athens bypass Perdikkas’ restrictions on timber exports and regain access to valuable shipbuilding materials.
The evidence does not prove that timber was the only motive behind the alliance. Political and military considerations also played important roles. Nevertheless, the timber trade provides a convincing explanation for why control of Macedonian territory mattered so much to Athens.
The episode also illustrates an important weakness in Athenian diplomacy. By supporting the king’s rivals, Athens risked destroying the goodwill necessary for future commercial cooperation. Diplomacy could create new opportunities, but it could also produce lasting hostility.
Treaties and the return to cooperation
Despite these conflicts, Athens continued to seek agreements with Macedonian rulers when its circumstances demanded it. The capture of Amphipolis by the Spartans in 424/423 BC weakened Athens’s independent access to the region’s resources. The city once again had strong reasons to seek timber from Macedonia.
Psoma discusses an agreement involving Athens, its allies, and Perdikkas II and his children, in which Macedonian oars were explicitly mentioned. The inscription known as IG I³ 89 provides evidence of the practical importance of these arrangements. Later, during the reign of Archelaos, Macedonian timber exports to Athens are also attested.
These agreements show that diplomatic relations could recover when the interests of both parties aligned. Athens needed timber and other naval supplies, while Macedonian kings could benefit from maintaining useful connections with a powerful Greek city-state.
Cooperation continued under later rulers. In the late 370s BC, during the reign of Amyntas III, Athens again established an alliance with Macedonia, and evidence indicates that timber was exported to the city. Psoma uses these developments to demonstrate the recurring relationship between Athenian naval needs and Macedonian diplomacy.
However, such cooperation was never guaranteed. Changes in military circumstances, dynastic struggles, and competition for territory could quickly disrupt the supply of timber.
