He married the wealthy Archidamia, and they had two children, Archidamus IV and Agesistrata. There is evidence that Eudamidas I owned the half of his wife's wealth in land. His reign of Sparta was a time of peace. Pausanias devotes more space to Agis II (427–400 BC) and Agesilaus II (400–360 BC) than to other kings, such as Agis III (338–330 BC) and Eudamidas I, whose lives he passed by briefly, as the Eurypontid line ‘fades’.

Title: Archidamus II
Content:  Archidamus II was a Eurypontid king of Sparta who reigned from approximately 476 BC to 427 BC. His father was Zeuxidamus (called Cyniscos by many Spartans). Zeuxidamus married and had a son, Archidamus. However, Zeuxidamus died before his father, Leotychidas. After the death of his son and heir, Leotychidas married Eurydame, the sister of Menius and daughter of Diactorides. While they had no male offspring, they did have a daughter, Lampito, whom Leotychidas gave in marriage to his grandson Archidamus. They had a son Agis II. Archidamus' later second marriage was to Eupoleia. The Ephors objected to this union, arguing that due to Eupolia's short stature, “She will bear us kinglets instead of kings”. He married her nonetheless and was for that fined by the Ephors. To them were born a son, Agesilaus II, and a daughter, Cynisca.

He interceded with his own father to spare his aites's (ἀΐτας, lover) father's life in a legal matter, an action which further intensified friction between Athens and Sparta. He later led the Spartan forces both before and during his rule. Archidamus headed the force sent to aid the Spartan army after its defeat by the Thebans at the Battle of Leuctra in 371 BC and was commander later during the fighting in the Peloponnese.
