Alliance with Argos, Elis and Mantinea
IG I3 83 Date: 420 BC
[Of the Argives, Mantineans], Eleans.[1] A treaty was made for a hundred years by the Athenians and by the Argives, Mantineans and Eleans with one another,
on behalf of themselves and the allies whom they rule on each side, without deceit or damage, by land and
by sea. It shall not be permitted to bear arms for hurt, either to the Argives, Eleans and Mantineans (5) and their allies against the Athenians and the allies whom the Athenians rule, or to the Athenians and the
allies whom the Athenians rule against the Argives, Eleans and Mantineans and their allies, by any craft
or contrivance. On these terms the Athenians and Argives and Mantineans and Eleans shall be allies for a hundred years. If enemies go against the land of the Athenians, the Argives and Mantineans and
Eleans shall go to Athens in support, as summoned by the Athenians, in the strongest way they can as
(10) they are able. If they ravage and depart, this city shall be an enemy of the Argives and Mantineans and Eleans and Athenians, and shall suffer harm at the hands of all these cities. It shall not be permitted to put an
end to the war against this city to any of the cities unless decided by all. Also the Athenians shall go in
support to Argos and Mantinea and Elis if enemies go against the land of the Argives or
Mantineans or Eleans, as summoned by these cities, in the strongest way they can
(15) as they are able. If they ravage and depart, this city shall be an enemy of the
Athenians and Argives and Mantineans and Eleans, and shall suffer harm at the hands of all these
cities. It shall not be permitted to put an end to the war against this city to any of the cities unless decided
by all. They shall not allow men bearing arms to pass for war through their own land and the land
of the allies whom each rule, nor by sea, unless all the cities vote that
(20) there shall be passage, the Athenians and Argives and Mantineans and Eleans. For those who go in support the sending
city shall provide food for up to thirty days after their arrival at the city which summoned
them to support, and on the same terms when they go back. If the city which invited it wishes to use the army
for a longer time, it shall provide food: for a hoplite, a light-armed or an archer three Aiginetan obols
for each day, and for a cavalryman an Aiginetan drachma. The inviting city
(25) shall have the command of the army when the war is in its own territory. If all the cities
decide in common to make a campaign, each of the cities shall have an equal share in the command. The treaty shall be sworn
to by the Athenians on behalf of themselves and their allies; the Argives and Mantineans and
Eleans and the allies of these shall swear by cities . . . .
