Why Athens had bad Military strength Alliances?

Answer 1

Athens had weakened military strength alliances primarily due to its overreliance on naval power and a democratic political structure that often hindered swift decision-making. The Athenian empire, while strong at sea, struggled to maintain effective land forces, which left it vulnerable to powerful land-based rivals like Sparta. Additionally, the shifting loyalties of its allies, who sometimes resented Athenian dominance, further eroded the effectiveness of its military alliances. This combination of factors ultimately contributed to Athens' difficulties in sustaining a cohesive and powerful military coalition.
