"History of Greece, Volume 06 (of 12)" by George Grote is a historical account written in the mid-19th century. This volume continues to explore the events and political dynamics surrounding Athens and its empire in the period leading up to the Peloponnesian War. Grote delves into the complexities of Athenian imperial policies, the relationships with its allies, and the sociopolitical landscape shaped by key figures such as Periklês. The opening of this volume outlines the Athenian political environment following the Thirty Years’ Truce. It details how the citizens of Athens became more engaged in governance, leading to an era of significant maritime expansion and the transformation of the Delian League into an Athenian empire. Key topics include the strengthening of Athenian naval power, the economic benefits derived from tribute collected from subject allies, and the resulting complacency that came from their dominance at sea. Furthermore, Grote introduces the political opposition led by Thucydidês, which critiqued Periklês for his policies concerning the management and expenditure of Athenian resources, foreshadowing the tensions that would eventually lead to war.
