Menander I Soter (Ancient Greek: Μένανδρος Σωτήρ, romanized: Ménandros Sōtḗr, lit. 'Menander the Saviour'; Pali: Milinda), sometimes called Menander the Great, was an Indo-Greek king (reigned c. 165/155 –130 BC) who administered a large territory in the northwestern regions of the Indian subcontinent and Central Asia. Menander is noted for having become a patron of Greco-Buddhism and is regarded as the greatest and most well-known of the Indo-Greek kings.
Menander might have initially been a prince or king of Bactria. After conquering the Punjab, as far as Taxila and Sagala, he established an empire which stretched from the Kabul River in the west to the Ravi River in the east, and from the Swat River valley in the north to Arachosia (the Helmand Province). The Greek geographer Strabo wrote that he "conquered more tribes than Alexander the Great." Ancient Indian writers indicate that he possibly launched expeditions southward into Rajputana (Rajasthan, Gujarat and Sindh) and central India (Gujarat and Malwa) and as far east down the Ganges River Valley as Pataliputra (Patna).
