How was Athens affected by the Trojan War?

Troy was a rising power that would have eventually threatened the later supremacy of Athens in Greek politics. At the end of the bronze age, Athens was not as prominent as it was in later years. The Greek armies were led by the kings of Mycenae and Sparta, and were called in the Iliad "Danaans" (a reference to Perseus' mother Danae and his role as the founding Greek king) or "Achaeans" (a reference to the power of the Achaean capital, Mycenae... Athens is in Attica).
