f. Bactria
After Alexander's death, Greek auxiliaries mutinied and were crushed by Perdiccas. Control over Bactria, frequently nominal, passed from Perdiccas (d. 319), to Eumenes (d. 316), to Antigonus, and to Seleucus, who campaigned in the eastern provinces (311–302).  1
c. 250–210?
Diodotus, the satrap of Bactria, made himself independent and conquered Sogdiana. He founded a dynasty that withstood the attacks of the Seleucids.  2
Euthydemus overthrew Diodotus II (c. 210?) and withstood a two-year siege at Bactra by Antiochus III before making an alliance (208–206?). After the defeat of Antiochus at Magnesia (190), Euthydemus and his son Demetrius began to expand into the Indus Valley. But while Demetrius was campaigning in the Punjab, Eucratides made himself king of Bactria (c. 170). Menander (c. 155–130) then became king of Bactria and extended his power into India. About 100 the Yuezhi crossed the Oxus River, breaking Bactrian Greek power and confining their territory to the Hindu Kush and the upper Indus and Swat Valleys. They were then overcome by the Sakas and Scytho-Parthians.  3
