Indo-Greeks are qualified, together with the Sakas, Kambojas, Pahlavas and Paradas as Kshatriya-pungava i.e. foremost among the Warrior caste, or Kshatriyas. The Majjhima Nikaya explains that in the lands of the Yavanas and Kambojas, in contrast with the numerous Indian castes, there were only two classes of people, Aryas and Religion In addition to the worship of the Classical pantheon of the Greek deities found on their coins (Zeus, Herakles, Athena, Apollo...), the Indo-Greeks were involved with local faiths, particularly with Buddhism, but also with Hinduism and Zoroastrianism. Interactions with Buddhism Chandragupta Maurya, the founder of the Mauryan Empire, conquered the Greek satraps left by Alexander, which belonged to Seleucus I Nicator of the Seleucid Empire. The Mauryan Emperor Ashoka would then establish the largest empire in the Indian Subcontinent through an aggressive expansion. Ashoka converted to Buddhism following the destructive Kalinga War, abandoning further conquests in favor of humanitarian reforms. Ashoka erected the Edicts of Ashoka to spread Buddhism and the 'Law of Piety' throughout his dominion. In one of his edicts, Ashoka claims to have converted his Greek population along with others to Buddhism. The last Mauryan Emperor Brihadratha was assassinated by Pushyamitra Shunga, the former senapati or "army lord" of the Mauryan Empire and founder of the Shunga Empire. Pushyamitra is alleged to have persecuted Buddhism in favor of brahmanism, likely in attempt to further remove the legacy of the Mauryan Empire. It is possible that Menander I Soter or the "Saviour king", choose Sakala as his capital due to the Buddhist presence there. Menander I, is stated to have converted to Buddhism in the Milinda Panha, which records the dialogue between Menander and the Buddhist monk Nagasena. Menander is claimed to have obtained the title of an arhat. The wheel he represented on some of his coins was most likely Buddhist Dharmachakra,. Another Indian text, the Stupavadana of Ksemendra, mentions in the form of a prophecy that Menander will build a stupa in Pataliputra. Plutarch also presents Menander as an example of benevolent rule, and explains that upon his death, the honour of sharing his remains was claimed by the various cities under his rule, and they were enshrined in "monuments" (μνημεία, probably stupas), in a parallel with the historic Buddha: The Butkara stupa was "monumentalized" by the addition of Hellenistic architectural decorations during Indo-Greek rule in the 2nd century BC.
