The book Economy, War, Strategy, and Institutions approaches the economic, political, and institutional peculiarities of the Achaean League, as well as Greece in general, during the period 389-146 BC.

Through extensive bibliography and contemporary approaches applied for the first time on such a subject, the present book explores the origins of the establishment of the Achaean League, as well as the other Greek leagues, highlighting the innovative political and economic institutions that the League established and implemented (such as equality among citizens, consulates, and magistracies), fully imbued with democratic ideals.

At the same time, it showcases the multifaceted actions of its key protagonists, Aratus and Philopoemen, who played a crucial role in establishing the Achaean League as a leading power in southern Greece, within a particularly demanding geopolitical environment, with shifts between friendly and rival players, such as Sparta, Macedonia, the Aetolian League, the Boeotian League, the Hellenistic Kingdoms of the East, and Rome.

Finally, this study illuminates the democratic way in which the Achaean League made its decisions on a range of critical timeless issues, concerning security and defense policy (peace or war), the state budget, fiscal and monetary policy, etc., while offering a new perspective on specific issues, such as its contribution to the formulation of the U.S. Constitution, and what lessons the European Union could draw from its organization for the future of Europe.
