With Eukratides I, we are for once lucky in finding more than very brief mentions about the Greco-Baktrian Kingdom in western historiography. A passage from the Roman historian Justin refers to his campaigns in India, in the course of which Eukratides prevailed over a certain 'Demetrios, King of India' (Justin XLI 6): this must be either Demetrios I or Demetrios II. The victor pushed the boundaries of the Greco-Baktrian Kingdom to their greatest extent and adopted the title 'Great King', but when he was returning home from India, he was killed by his unnamed son and co-ruler - perhaps Eukratides II, Heliokles or Plato. Whoever the offender was, the patricide must have resulted from bitter hate, as Justin reports that the murderer 'drove his chariot through his [father's] blood, and ordered his body to be cast out unburied'
