Caucasus in the country of the Yonas, to be present at the building of the Ruwanwelisaya. Milindapanha Another example is that of the Milinda Panha (Chapter I), where "Yonaka" is used to refer to the great Indo-Greek king Menander (160–135 BC), and to the guard of "five hundred Greeks" that constantly accompanies him. Invasion of India The Vanaparava of Mahabharata contains prophecies that "Mleccha kings of the Shakas, Yavanas, Kambojas, Bahlikas etc. shall rule the earth un-righteously in Kaliyuga ...". This reference apparently alludes to chaotic political scenario following the collapse of the Maurya and Shunga Empires in northern India and its subsequent occupation by foreign hordes such as of the Yonas, Kambojas, Sakas and Pahlavas. There are important references to the warring Mleccha hordes of the Shakas, Yavanas, Kambojas, the Pahlavas and others in the Bala Kanda of Valmiki's Ramayana. Indologists like Dr H. C. Raychadhury, Dr B. C. Law, Dr Satya Shrava and others see in these verses the clear glimpses of the struggles of the Hindus with the mixed invading hordes of the barbaric Sakas, Yavanas, Kambojas, Pahlavas etc. from north-west. The time frame for these struggles is 2nd century BCE downwards. The other Indian records prophecies the 180 BCE Yona attacks on Saket, Panchala, Mathura and Pataliputra, probably against the Shunga Empire, and possibly in defence of Buddhism: "After having conquered Saketa, the country of the Panchala and the Mathuras, the Yavanas, wicked and valiant, will reach Kusumadhvaja ("The town of the flower-standard", Pataliputra). The thick mud-fortifications at Pataliputra being reached, all the provinces will be in disorder, without doubt. Ultimately, a great battle will follow, with tree-like engines (siege engines)." "The Yavanas will command, the Kings will disappear. (But ultimately) the Yavanas, intoxicated with fighting, will not stay in Madhadesa (the Middle Country); there will be undoubtedly a civil war among them, arising in their own country, there will be a terrible and ferocious war." The "Anushasanaparava" of the Mahabharata affirms that the country of Majjhimadesa was invaded the Yavanas and the Kambojas who were later utterly defeated. The Yona invasion of Majjhimadesa ("middle country, midlands") was jointly carried out by the Yonas and the Kambojas. Majjhimadesa here means the middle of Greater India which then included Afghanistan, Pakistan and large parts of Central Asia.
