Powerful Hellenistic states were established in the areas of Bactria and Sogdiana, and later northern India for three centuries following the conquests of Alexander the Great around 330 BCE: the Seleucid empire until 250 BCE, followed by the Greco-Bactrian kingdom until 130 BCE, and the Indo-Greek kingdom from 180 BCE to around 10 BCE.
The clearest examples of Hellenistic art are found in the coins of the Greco-Bactrian kings of the period, such as Demetrius I of Bactria. Many coins of the Greco-Bactrian kings have been unearthed, including the largest silver and gold coins ever minted in the Hellenistic world, ranking among the best in artistic and technical sophistication: they "show a degree of individuality never matched by the often more bland descriptions of their royal contemporaries further West". ("Greece and the Hellenistic world").
These Hellenistic kingdoms established cities on the Greek model, such as in Ai-Khanoum in Bactria, displaying purely Hellenistic architectural features, Hellenistic statuary, and remains of Aristotelician papyrus prints and coin hoards.
