History of the Peloponnesian War

The Argives began by accepting this proposal, and the Lacedaemonian army returned home from Tegea. After this intercourse was renewed between them, and not long afterwards the same party contrived that the Argives should give up the league with the Mantineans, Eleans, and Athenians, and should make a treaty and alliance with the Lacedaemonians; which was consequently done upon the terms following:—

The Lacedaemonians and Argives agree to a treaty and alliance for fifty years upon the terms following:—1. All disputes shall be decided by fair and impartial arbitration, agreeably to the customs of the two countries.2. The rest of the cities in Peloponnese may be included in this treaty and alliance, as independent and sovereign, in full enjoyment of what they possess; all disputes being decided by fair and impartial arbitration, agreeably to the customs of the said cities.

3. All allies of the Lacedaemonians outside Peloponnese shall be upon the same footing as the Lacedaemonians themselves, and the allies of the Argives shall be upon the same footing as the Argives themselves, continuing to enjoy what they possess.

4. If it shall be anywhere necessary to make an expedition in common, the Lacedaemonians and Argives shall consult upon it and decide, as may be most fair for the allies.
