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")). It is during this period that the fusion of Hellenistic and South Asian mythological, artistic and religious elements becomes most apparent, especially in the region of Gandhara. Local Greek rulers still exercised a feeble and precarious power along the borderland, but the last vestige of the Greco-Indian rulers were finished by a people known to the old Chinese as the Yeuh-Chi. Indo-Scythian Kingdom The Indo-Scythians were descended from the Sakas (Scythians) who migrated from Central Asia into South Asia from the middle of the 2nd century BCE to the 1st century BCE. They displaced the Indo-Greeks and ruled a kingdom that stretched from Gandhara to Mathura. The first Indo-Scythian king Maues established Saka hegemony by conquering Indo-Greek territories. The power of the Saka rulers declined after the defeat to Chandragupta II of the Gupta Empire in the 4th century. Indo-Parthian Kingdom The Indo-Parthian Kingdom was ruled by the Gondopharid dynasty, named after its first ruler Gondophares. For most of their history, the leading Gondopharid kings held Taxila (in the present Punjab province of Pakistan) as their residence, but during their last few years of existence the capital shifted between Kabul and Peshawar. These kings have traditionally been referred to as Indo-Parthians, as their coinage was often inspired by the Arsacid dynasty, but they probably belonged to a wider groups of Iranic tribes who lived east of Parthia proper, and there is no evidence that all the kings who assumed the title Gondophares, which means "Holder of Glory", were even related. Kushan Empire The Yuezhi nomads had driven the Sakas from the highlands of Central Asia, and were themselves forced southwards by the nomadic Xiongnu. One group, known as the Kushan, took the lead, and its chief, Kadphises I, seized vast territories extending south to the Kabul valley. His son Kadphises II conquered North-Western India, which he governed through his generals. His immediate successors were the fabled Hindu kings: Kanishka, Huvishka, and Vasushka or Vasudeva, of whom the first reigned over
