The classical Buddhist text Milinda Pañha praises Menander, saying there was "none equal to Milinda in all India". His empire survived him in a fragmented manner until the last independent Greek king, Strato II, disappeared around 10 CE. Around 125 BCE, the Greco-Bactrian king Heliocles, son of Eucratides, fled from the Yuezhi invasion of Bactria and relocated to Gandhara, pushing the Indo-Greeks east of the Jhelum River. The last known Indo-Greek ruler was Theodamas, from the Bajaur area of Gandhara, mentioned on a 1st-century CE signet ring, bearing the Kharoṣṭhī inscription ""Su Theodamasa"" (""Su"" was the Greek transliteration of the Kushan royal title ""Shau"" ("Shah" or "King")). Various petty kings ruled into the early 1st century CE, until the conquests by the Scythians, Parthians and the Yuezhi, who founded the Kushan dynasty.
