Leonidas II in Wikipedia

Leonidas II (Greek: Λεωνίδας B; "Lion's son", "Lion-like"), was Agiad King of Sparta from 254 to 235 BC. He was raised at the Persian Court, and according to Plutarch's Life of Agis IV, he married a Persian woman. According to other sources, this non-Spartan wife was actually a Seleucid, possibly the daughter of Seleucus I Nicator by his Persian wife Apama. She was therefore not fully Persian, but half-Macedonian and half-Persian. His Persian-influenced lifestyle, his non-Spartan (therefore foreign) wife and his half-Spartan children would all be made issues by the ephor Lysander, the co-king Agis IV and their supporters. Leonidas III opposed the attempted reforms of his Eurypontid co-regent, Agis IV. The ephor, Lysander, claimed to have seen a sign from the gods against Leonidas, and Leonidas fled to avoid his trial. In his absence, Leonidas was deposed from the throne and replaced by his son-in-law, Cleombrotus. Family He was the father of two children by his wife Cratisiclea,[1] who belonged to the Seleucid dynasty founded by Seleucus Nicator.[2] His son Cleomenes III eventually succeeded him, having been married at age 18 to Agiatis (d. 224 BC), widow of Agis IV, the Eurypontid king; they had at least one son together who died in Egypt with his grandmother. His daughter Chilonis was married to Cleombrotus who replaced his father-in-law as king for some time. She was notable for her fidelity to her father, whom she followed into exile, and then to her husband whom she also followed into exile after her father returned to power.[3]
