Indo-Greeks, Shakas & Kushanas

Between the fall of the Mauryas and the rise of the Guptas, a succession of Central Asian invaders ruled north-west and northern India — the Indo-Greeks, the Shakas (Indo-Scythians) and the Kushanas — and, far from being a dark age, this era (c. 200 BCE–300 CE) was one of extraordinary cultural synthesis. Fix the vocabulary first: Yavanas is the Indian name for Greek-speaking foreigners; a satrap (Indian kshatrapa) is a provincial governor, a title of Persian–Greek origin; and the Kushanas were a branch of the nomadic Yuezhi (Tocharians) from the Chinese frontier. These dynasties gave India its first portrait coins and bilingual inscriptions, the first anthropomorphic image of the Buddha (Gandhara & Mathura art), the Shaka era that is now the national calendar, and the Silk Route trade that linked India to Rome and China — while themselves being absorbed into the Indian religious and social order.

1. The Indo-Greeks (c. 200–10 BCE)

• The Indo-Greeks descended from Alexander's Bactrian satrapies, which broke from the Seleucids under Diodotus I (~250 BCE); Demetrius I first pushed into India (~190 BCE). Their most celebrated king was Menander I (Milinda) (~165–130 BCE), remembered in the Milindapanha — a Pali philosophical dialogue with the monk Nagasena on the soul, rebirth and nirvana — after which he is said to have converted to Buddhism. (The text is paracanonical, not part of the Tipitaka.)
• Their lasting contribution was numismatic and artistic: they introduced to India the die-struck portrait coin (the first royal portraits and the first bilingual coins — Greek on the obverse, Kharosthi on the reverse), and their Hellenistic realism (drapery, acanthus, scroll) became the seed of Gandhara art. Some Indo-Greeks even worshipped Indian deities, and the age produced the famous Heliodorus pillar at Besnagar (Vidisha, ~110 BCE), where the Greek envoy Heliodorus dedicated a Garuda pillar to Vasudeva (Vishnu) — the earliest known foreigner to adopt Vaishnavism. Squeezed by the Shakas and Parthians, the last Indo-Greek king, Strato II, fell around 10 CE.

2. The Shakas (Indo-Scythians)

• The Shakas were Iranian nomads pushed into India by the Yuezhi, entering via Bactria and Sindh to rule in several branches — Maues in the Taxila/NW branch, Rajuvula at Mathura, and the long-lived Western Kshatrapas in Gujarat and Malwa. They governed through kshatrapas (satraps), often in a father–son co-regency, and integrated readily into Indian society, patronising Hinduism (especially Shaivism) — the Manusmriti absorbing them as "vratya Kshatriyas" (lapsed Kshatriyas).
• Their greatest ruler was Rudradaman I, whose Junagadh Rock Inscription (150 CE) is the first long inscription in chaste (correct) Sanskrit prose — a landmark in the shift from Prakrit to Sanskrit — and records his repair of the Sudarshana Lake (built under Chandragupta Maurya, modified by Ashoka's Yavana governor Tushaspa) and his victories over the Satavahanas. The Western Kshatrapa Nahapana had earlier been defeated by Gautamiputra Satakarni, and the whole Shaka dynasty was finally extinguished by Chandragupta II Vikramaditya (~415 CE). Most consequentially, the Shaka era of 78 CE became the base of the Indian National Calendar — not to be confused with the Vikram Samvat of 57 BCE.

3. The Kushanas & Kanishka

• The Kushanas were one of five clans of the Yuezhi (Tocharian) nomads, unified under Kujula Kadphises, who founded the dynasty and took Kabul and Gandhara; Vima Kadphises then reached Mathura and issued India's first large-scale gold dinara (modelled on Rome's denarius) as a Shaivite. The empire peaked under Kanishka I (c. 127 CE — his exact accession date is famously debated), stretching from the Oxus to the Ganga plains, its capital at Purushapura (Peshawar) astride the Silk Route.
• Kanishka is above all the great Buddhist patron: he convened the Fourth Buddhist Council (in Kashmir, presided by Vasumitra with Ashvaghosha present), which compiled the Mahavibhasha and formalised the Sarvastivada school, even as Mahayana Buddhism rose and spread along the Silk Route to Central Asia and China. Yet his coins are strikingly eclectic — the Buddha alongside Greek (Helios), Iranian (Mithra, Nana) and Hindu (Shiva) deities — and he bore the composite title Maharaja Rajatiraja Devaputra ("great king, king of kings, son of god"), blending Indian, Iranian and Chinese imperial vocabulary. His court hosted the poet-philosopher Ashvaghosha (Buddhacharita) and, by tradition, the physician Charaka.

4. Gandhara, Mathura & the first Buddha image

• The Kushana age produced the first anthropomorphic images of the Buddha, ending the aniconic tradition. The Gandhara school (NW India/Pakistan) is Greco-Roman in style — the Buddha modelled on Apollo, with wavy hair, a toga-like sanghati, elongated features and classical drapery, carved in grey/blue schist. The Mathura school (UP) grew from the indigenous Yaksha tradition — a robust, sensuous Buddha in a thin clinging robe, carved in red spotted sandstone. The scholarly consensus is that the two developed roughly simultaneously (~1st c. CE) rather than one strictly preceding the other.
• A third, southern, contemporary school — Amaravati (Andhra) — worked in white limestone with dynamic narrative panels (treated in the Satavahana leaf). The comparison of these schools is a classic exam question.

5. Trade, administration & decline

• The Kushana empire was the lynchpin of the Silk Route, linking China through Central Asia to Parthia and Rome. India exported cotton textiles, spices and gems and imported Roman glass and wine, and the Periplus of the Erythraean Sea names the ports of Barbaricum (Sindh) and Barygaza (Bharuch); the Begram hoard (Roman glass, Indian ivory, Chinese lacquer) and the gold dinara are vivid evidence of this global commerce, of which Taxila was a great hub. Administratively the Kushanas ruled through satraps and a commander-in-chief, introducing Iranian feudal elements and Greek-titled governors (strategos).
• The empire declined under Sassanid pressure (Ardashir I from 224 CE; then Shapur I), fragmenting into local chiefdoms and the vassal Kidarite Kushanas, with the east absorbed by Samudragupta's Gupta empire in the 4th century. Kushana influence lived on through the Kidarites and the Hephthalites (White Huns).
