 The stele was originally erected near the statue of Zues Eleutherios and in front of the Stoa of Zeus in Athens.The decree, often known as the "Charter of the Second Athenian Confederacy," formalized earlier Athenian diplomacy inviting states to join Athens and her allies in a permanent alliance.The stele lists around sixty states as being members of the Second Athenian Confederacy, although it is possible that additional states may have also been members.
