Euthydemus I c. 260 BC – 200/195 BC) was a Greco-Bactrian king and founder of the Euthydemid dynasty. He is thought to have originally been a satrap of Sogdia, who usurped power from Diodotus II in 224 BC. Literary sources, notably Polybius, record how he and his son Demetrius resisted an invasion by the Seleucid king Antiochus III from 209 to 206 BC. Euthydemus expanded the Bactrian territory into Sogdia, constructed several fortresses, including the Derbent Wall in the Iron Gate, and issued a very substantial coinage.
