Indo-Greek Kingdoms

c. 200 BCE – 10 CE

Overview

Hellenistic kingdoms in NW India founded by Demetrius I of Bactria. Peak under Menander I (Milinda). Famous for Greco-Buddhist art and bilingual coinage. Displaced by Sakas ~10 BCE.

Hellenistic Kingdoms (Alexander → Indo-Greek)

Succession of Hellenistic states in Central and South Asia: Alexander's brief conquest, the Seleucid eastern satrapies, the independent Greco-Bactrian Kingdom, and the Indo-Greek kingdoms that survived until c. 10 BCE.

Territory Phases

Alexander's Empire327 BCE – 315 BCE
Alexander the Great's conquest reached the Indus and Punjab (327-325 BCE). Defeated Porus at the Hydaspes, founded cities including Alexandria-on-the-Indus and Bucephala. His troops mutinied at the Hyphasis (Beas), forcing Alexander to turn back. He died in Babylon in 323 BCE; the eastern satrapies passed to his successors.
Seleucid Empire (in India)312 BCE – 300 BCE
Seleucus Nicator inherited the eastern satrapies of Alexander's empire after the Wars of the Diadochi. Briefly held Gandhara, Arachosia, and Gedrosia until Chandragupta Maurya's conquest. The Chandragupta-Seleucus treaty (~305 BCE) ceded these territories in exchange for 500 war elephants, sealing the friendship between the Mauryan and Seleucid dynasties.
Greco-Bactrian Kingdom255 BCE – 180 BCE
Greco-Bactrian Kingdom — Hellenistic successor state in Bactria and Sogdiana north of the Hindu Kush. Founded when Diodotus I declared independence from the Seleucids ~250 BCE. Capital at Bactra (Balkh) and the unique Greek city of Ai-Khanoum on the Amu Darya. Famous for refined Hellenistic coinage, Greek-language inscriptions, and cultural fusion with local traditions.
Indo-Greek Kingdoms180 BCE – 85 BCE
Indo-Greek Kingdoms — established when Demetrius I of Bactria crossed the Hindu Kush ~180 BCE. Peak under Menander I (Milinda, ~165-130 BCE), who extended rule deep into the Indo-Gangetic plain and is celebrated in the Buddhist text 'Milinda Panha' (Questions of King Milinda). Famous for bilingual Greek-Kharoshthi coinage and the synthesis of Hellenistic and Indian traditions visible in Gandharan art.
Indo-Greek Kingdoms (Late)90 BCE – 10 BCE
Late Indo-Greek period — fragmenting under pressure from the Saka (Indo-Scythian) migrations from the north and the Yuezhi from Central Asia. Multiple small Indo-Greek kingdoms persisted in pockets of Gandhara and the upper Indus. The last Indo-Greek king Strato II was defeated by the Sakas around 10 BCE, ending nearly two centuries of Greek rule in northwest India.

Key Rulers

Alexander III of Macedon

Also known as: Alexander the Great, Sikandar

336 BCE – 323 BCE

★★★★★

Macedonian king who crossed the Hindu Kush and defeated Porus at the Hydaspes (326 BCE). His troops mutinied at the Beas, forcing retreat. Died in Babylon 323 BCE.

Seleucus I Nicator

305 BCE – 281 BCE

★★★★

Founder of the Seleucid Empire. Inherited eastern satrapies but ceded them to Chandragupta Maurya (~305 BCE) in exchange for 500 war elephants.

Diodotus I

250 BCE – 230 BCE

★★★★

Seleucid satrap of Bactria who declared independence ~250 BCE, founding the Greco-Bactrian Kingdom.

Demetrius I of Bactria

200 BCE – 180 BCE

★★★★

Greco-Bactrian king who crossed the Hindu Kush ~180 BCE, establishing Indo-Greek rule in the Punjab and Gandhara.

Apollodotus I

Also known as: Apollodotos I Soter

180 BCE – 160 BCE

★★

Early Indo-Greek king, possibly a kinsman or general of Demetrius I. Consolidated Greek control over Gandhara, the western Punjab, and Sindh, and issued an abundant bilingual Greek/Kharoshthi coinage (elephant and humped-bull types) that circulated widely; the Periplus of the Erythraean Sea (§47) records that drachms of both Apollodotus and Menander were still passing as currency at Barygaza generations later.

Eucratides I

170 BCE – 145 BCE

★★★★

Rival Indo-Greek king who seized Bactria from the Euthydemid line. Issued the largest known gold coin of antiquity. His conflicts with Menander I fragmented Indo-Greek power.

Menander I

Also known as: Milinda

165 BCE – 130 BCE

★★★★★

Greatest Indo-Greek king, ruling from Sagala (Sialkot). Extended Indo-Greek territory deep into the Gangetic plain. Celebrated in the Buddhist Milindapanha for his philosophical dialogue with the monk Nagasena.

Strato I

Also known as: Strato I Soter

130 BCE – 110 BCE

★★

Indo-Greek king of the eastern Punjab in the line of Menander I. During his minority his mother Agathokleia ruled as regent and struck joint coinage bearing her own portrait and name — among the very few women named on Hellenistic coins. His reign marks the onset of post-Menander fragmentation among the Indo-Greek kings.

Antialcidas

Also known as: Antialcidas Nikephoros

115 BCE – 95 BCE

★★

Indo-Greek king ruling from the Paropamisadae and Gandhara (capital at Taxila). His ambassador Heliodorus erected the Garuda pillar at Besnagar (Vidisha) at the Shunga court of Bhagabhadra, dedicated to Vasudeva — the foremost surviving evidence of Indo-Greek diplomacy and a Greek's adoption of Indian Bhagavata devotion.

Hippostratus

Also known as: Hippostratos Soter

65 BCE – 55 BCE

★

One of the last major Indo-Greek kings of the western Punjab. His defeat by the Indo-Scythian king Azes I (c. 55 BCE) ended significant Greek control in the western Punjab and Gandhara and confined the surviving Greek kings to a shrinking pocket of the eastern Punjab around Sagala.

Strato II

25 BCE – 10 BCE

★★★

Last known Indo-Greek king, ruling a small domain in the eastern Punjab. Defeated by the Indo-Scythians (Sakas) ~10 BCE, ending Greek rule in India.

Key Events

Battle of the Hydaspes326 BCE

Alexander defeated King Porus on the Hydaspes (Jhelum) river. Despite Porus's war elephants, Alexander's tactical river crossing secured victory. Porus was reinstated as a vassal.

Bactrian secession from Seleucids250 BCE

Diodotus I, Seleucid satrap of Bactria, declared independence ~250 BCE, founding the Greco-Bactrian Kingdom as a separate Hellenistic state.

Demetrius' invasion of India180 BCE

Demetrius I crossed the Hindu Kush ~180 BCE, conquering Gandhara and the Punjab and establishing Indo-Greek rule in the Indian subcontinent.

Eucratides' war and the division of the Greek realm165 BCE

Eucratides I of Bactria warred against the Euthydemid Indo-Greek kings (c. 170-145 BCE), seizing the Paropamisadae around Kabul and substantially disrupting the political link between Bactria and the Indian territories — though Menander I subsequently recovered ground east of the Hindu Kush. The conflict divided the Greco-Bactrian and Indo-Greek spheres and accelerated Indo-Greek fragmentation.

Milindapanha — Menander's dialogue with Nagasena150 BCE

The Milindapanha records a philosophical dialogue between Indo-Greek king Menander I (Milinda) and the Buddhist monk Nagasena at Sagala. It is a key text of Theravada Buddhism and primary evidence for Menander's engagement with Buddhism.

Menander I's conquests into the Gangetic plain145 BCE

At the height of Indo-Greek power Menander I campaigned east of the Punjab. Strabo, citing Apollodorus of Artemita, claims he conquered more peoples than Alexander, and Indian sources (Patanjali, the Yuga Purana) record Yavana raids reaching Saketa, Mathura, and even Pataliputra. The deepest eastern advances were raids rather than lasting administration.

Heliodorus Pillar at Besnagar113 BCE

Heliodorus, a Greek (Yona) ambassador of the Indo-Greek king Antialcidas, erected a Garuda column at Besnagar (Vidisha) at the court of the Shunga king Bhagabhadra, dedicated to Vasudeva (Vishnu). Its Brahmi inscription is the foremost epigraphic evidence of Indo-Greek diplomacy and a Greek's devotion to a Bhagavata deity.

Azes I defeats Hippostratus55 BCE

The Indo-Scythian king Azes I defeated the Indo-Greek king Hippostratus c. 55 BCE, conquering the western Punjab and Pushkalavati. The surviving Greek kings were confined to a shrinking pocket of the eastern Punjab around Sagala until the end of Greek rule c. 10 BCE.

End of Indo-Greek kingdoms10 BCE

The last Indo-Greek king Strato II was defeated by the Indo-Scythians (Sakas) ~10 BCE, ending nearly three centuries of Greek political presence in the Indian subcontinent.
