Eucratides I the Great (Koinē Greek: Εὐκρατίδης, Eúkratides Mégas) (reigned 172/171–145 BC) was one of the most important Greco-Bactrian kings. Eucratides overthrew the Euthydemid dynasty and restored the Diodotids to power. He fought against the easternmost Hellenistic and Indian rulers in India, holding territory in the Indus and as far as Barigaza until he was finally defeated by Menander and pushed back to Bactria. Eucratides minted a vast and prestigious coinage, suggesting a rule of considerable importance and prosperity. His son, Heliocles I was the last Greek king to rule in Bactria, as the Yuezhi overran the country c. 120 BC.
Eucratides was born c.204 BC in the Hellenistic city of Ai-Khanoum, to 'Heliocles' and 'Laodice' as depicted on various finds of his coinage. His parents were likely members of the ousted Diodotid dynasty. It is unclear exactly what background or motive Eucratides had, or whether he and his family held any positions of rank during the reigns of Euthydemus I and Demetrius I.
Eucratides came to the throne by overthrowing the Euthydemid dynasty in Bactria, possibly when its king, Demetrius was conquering northwestern India. The king whom Eucratides dethroned in Bactria was probably Antimachus I.
It is unclear whether Eucratides was a Diodotid Bactrian nobleman who raised a rebellion, or, according to the claims of some scholars, a cousin of the Seleucid king Antiochus IV Epiphanes who was trying to regain the Bactrian territory. The Seleucid claim is highly unlikely and has been discredited by modern historians, and it is believed that Eucratides mother, Laodice was solely of the Diodotid dynasty. Justin explains that Eucratides acceded to the throne at about the same time as Mithridates, whose rule is accurately known to have started in 171 BC, thereby giving an approximate date for the accession of Eucratides:
Almost at the same time that Mithridates ascended the throne among the Parthians, Eucratides began to reign among the Bactrians – Justin, trans. J. S. Watson
Some of the coins of Eucratides represent his parents, where his father is named Heliocles, and his mother, Laodice, who is depicted wearing a royal diadem and therefore of royal descent. Narain and other modern authors propose that she was a daughter of Diodotus I.
Having become master of Bactria after de-throning the Euthydemid dynasty, Eucratides was faced with a Parthian invasion which began when Demetrius I was conquering India. Having taken Tapuria and Margiana from Demetrius in about 170 BC, the powerful Mithridates I attempted to conquer Bactria itself but was checked by Eucratides who wisely reformed the Diodotid alliance with the Parthia, likely paying a sum of Indian war-Elephants. Having secured his western borders, Eucratides then conquered parts of the India, campaigning as far south as Barigaza (modern day Bharuch), solidifying Greek presence in Northern India with the Indo-Greek Kingdom. According to the single remaining source, Roman historian Justin, Eucratides defeated Demetrius of India, but the identity of this king is uncertain: he could be either Demetrius I, or Demetrius II, but more likely Menander I.
Numismatic evidence suggests that Eucratides I was a contemporary of the Indo-Greek kings Apollodotus I, Apollodotus II and Diodotus III. In any case, Eucratides' advances into India are proved by his abundant bilingual coinage that are spread all over northern India and Pakistan.
The city of Eucratideia (Εὐκρατίδεια), which is mentioned by ancient Greek geographers as city of great wealth straddling the Oxus River, was probably named after Eucratides. It might have been a totally new foundation or an existing city which he had renamed after himself. The location of the city is uncertain, but it was probably Ai-Khanoum or perhaps Dilbarjin.
Justin ends his account of Eucratides' life by claiming that the warlike king was murdered on his way back from India by his son, who hated Eucratides so much that he mutilated and dragged his dead body after his chariot. This may have been a misinterpretation by Justin, and the regicide could instead have been perpetrated by an Euthydemid prince, Demetrius II, the son and successor of Demetrius I. Justin appears to believe Eucratides was killed by his own son, Heliocles I, but this is unlikely as patricide was uncommon in the Hellenistic age.
The murder of Eucratides probably brought about a civil war amongst the members of the dynasty. The successors to Eucratides were Eucratides II and Heliocles I (145–130 BC), who was the last Greek king to reign in Bactria. Once the Yuezhi tribes overpowered Heliocles, the Greco-Bactrians lost control of the provinces north of the Hindu Kush.
Two other members of the dynasty were Plato of Bactria and probably Demetrius II, who in that case was not identical with the king Justin claimed was the enemy of Eucratides I.
The rule of the Greco-Bactrians soon crumbled following these numerous wars:
However, the rule of the Indo-Greeks over territories south of the Hindu Kush lasted for a further 150 years, ultimately collapsing under the pressure of the Yüeh-chih and Scythian (Saka) invasions in around 10 BC, with the last Indo-Greek ruler Strato II.
Full account of Justin on Eucratides:
"Almost at the same time that Mithridates ascended the throne among the Parthians, Eucratides began to reign among the Bactrians; both of them being great men. But the fortune of the Parthians, being the more successful, raised them, under this prince, to the highest degree of power; while the Bactrians, harassed with various wars, lost not only their dominions, but their liberty; for having suffered from contentions with the Sogdians, the Drangians, and the Indians, they were at last overcome, as if exhausted, by the weaker Parthians. Eucratides, however, carried on several wars with great spirit, and though much reduced by his losses in them, yet, when he was besieged by Demetrius king of the Indians, with a garrison of only three hundred soldiers, he repulsed, by continual sallies, a force of sixty thousand enemies. Having accordingly escaped, after a five months’ siege, he reduced India under his power. But as he was returning from the country, he was killed on his march by his son, with whom he had shared his throne, and who was so far from concealing the murder, that, as if he had killed an enemy, and not his father, he drove his chariot through his blood, and ordered his body to be cast out unburied."— Justin, Epitome of the Philippic History of Pompeius Trogus, XLI 6.1-5, IIe CE.
Da Afghanistan Bank which is the central bank of Afghanistan, in its seal has a Eucratides I-era coin having the Greek text, "ΒΑΣΙΛΕΩΣ ΜΕΓΑΛΟΥ ΕΥΚΡΑΤΙΔΟΥ" which means “Of the great king Eucratides.”
