The Seleucid king Seleucus II Callinicus undertakes an expedition into the interior of Iran to try to regain Parthia, but his efforts come to nothing. According to some sources, he is even taken prisoner for several years by the Parthian king, Arsaces I. Other sources mention that he establishes a peace with Arsaces I by recognising his sovereignty over Parthia.
Roman Republic
Despite the opposition of the Roman Senate and of his own father, the Roman political leader Gaius Flaminius Nepos wins the passage of a measure to distribute land among the plebeians. The Romans decide to parcel out land north of Rome (the Ager Gallicus) into small holdings for its poorer citizens whose farms have fallen into ruin during the First Punic War.
