"Euthydemus I (Greek: Εὐθύδημος) c. 260 BC – 200/195 BC) was a Greco-Bactrian king. He is thought to have originally been a general or governor, who seized the throne by force from Diodotus II or Antiochus Nicator around 230 or 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 to encompass all of Sogdia, Ferghana and Margiana, and constructed several fortresses, including the Wall of Darband, separating Bactria from Sogdia, and issuing a very substantial coinage. Euthydemus was the founder of the Euthydemid dynasty, that ruled until 10 CE with Strato III in Northern India." - (en.wikipedia.org 11.08.2021)
