There are records that show that the Northwest of India was once ruled by Greeks.
However the relations between the Greeks and India,especially the Tamils date back to centuries earlier.
These Greek Kings later ,some of them, converted to Buddhism.
They held both Hinduism and Buddhism that they minted Coins in honor of the Deities of these religions.though Buddhism does not endorse the view of God.
These coins date back to 185 BC.
- “Arunad Yavanah Sāketam” (“The Yavanas (Greeks) were besieging Saketa”)
- “Arunad Yavano Madhyamikām” (“The Yavanas were besieging Madhyamika” (the “Middle country”)).-Patanjali in Mahabhasya.
“Sudras will also be utterers of bho (a form of address used towards an equal or inferior), and Brahmins will be utterers of arya (a form of address used towards a superior), and the elders, most fearful of dharma, will fearlessly exploit the people. And in the city the Yavanas, the princes, will make this people acquainted with them: but the Yavanas, infatuated by war, will not remain in Madhyadesa.”
—Yuga Purana, Paragraph 55–56, 2002 edition.
There is also significant archaeological evidence, including some epigraphic evidence, for the Indo-Greek kings, such as the mention of the “Yavana” embassy of king Antialcidason the Heliodorus pillar in Vidisha.
Agathocles Dikaios (Greek: Ἀγαθοκλῆς ὁ Δίκαιος; epithet meaning: “the Just”) was a Buddhist Indo-Greek king, who reigned between around 190 and 180 BC. He might have been a son of Demetrius and one of his sub-kings in charge of the Paropamisadebetween Bactria and India. In that case, he was a grandson of Euthydemus whom he qualified on his coins as Βασιλεὺς Θεός,Basileus Theos (Greek for “God-King”).
At the same time, Agathocles issued an intriguing range of bilingual coinage, displaying what seems to be Buddhist as well as Hinduist symbolism. The coins, manufactured according to the Indian standard, using either Brahmi, Greek orKharoshthi (a first in the Greek world), and displaying symbols of the various faiths in India, tend to indicate a considerable willingness to accommodate local languages and beliefs, to an extent unseen in subsequent Indo-Greek kings. They may be indicative of the considerable efforts of the first Indo-Greek kings to secure support from Indian populations and avoid being perceived as invaders, efforts which may have subsided once the Indo-Greek kingdoms were more securely in place.’
