seems to have died out, and their place was taken by the foreign dynasty of the Kshaharatas, the Saka satraps of Surashtra (Kathiawar), who in 120 had mastered Ujjain and Gujarat and had built up a rival kingdom to the north. Since about A.D. 40 the coast cities had been much enriched by trade with the Roman empire, which both the Satavahanas and the satraps did much to encourage; but after the fall of Palmyra (273) and the extinction of the main Kshaharata dynasty (c. 300) this commerce fell into decay. The history of the century and a half that follows is very obscure; short-lived Saka dynasties succeeded one another until, about 388, the country was conquered by the Guptas of Magadha, who kept a precarious tenure of it till about 470, when their empire was destroyed by the White Huns, or Ephthalites (q.v.), who, after breaking the power of Persia and assailing the Kushan kingdom of Kabul, poured into India, conquered Sind, and established their dominion as far south as the Nerbudda. Under the Hun tyranny, which lasted till the overthrow of the White Huns on the Oxus by the Turks (c. 565), native dynasties had survived, or new ones had established themselves. In Kathiawar a chief named Bhatarka, probably of foreign origin, had established himself at Valabhi (Wala) on the ruins of the Gupta power (c. 500), and founded a dynasty which lasted until it was overthrown by Arab invaders from Sind in 770.[1] The northern Konkan was held by the Mauryas of Puri near Bombay, the southerly coast by the Kadambas of Vanavasi, while in the southern Deccan Chalukyas and Rashtrakutas struggled for the mastery. A new power, too, appeared from the north: the Gurjaras (ancestors, it is supposed, of the Gujar caste), who had probably entered India with the White Huns, established their power over Gujarat and (c. 600) overran north-eastern Kathiawar, made the raja of Valabhi their tributary, and established a branch at Broach (585-740). During the short-lived empire of Harsha (d. 647 or 648), Malwa, Gujarat and Kathiawar were subject to his sway; but the southern boundary of his kingdom was the Nerbudda, south of which the Chalukyas in the 7th century, having overcome the Rashtrakutas and other rivals, had absorbed the smaller kingdoms into their empire. In 710-711 (92 A.H.) the Arabs invaded India, and in 712 conquered and established themselves in Sind; they did not, however, attempt any serious attack on the Gurjara and Chalukya empires, confining themselves to more or less serious raids. In 770 they destroyed the city of Valabhi and, as already mentioned, brought its dynasty to an end. Meanwhile the Chalukyas, after successfully struggling with the Pallavas (whose capital was taken by Vikramaditya II., c. 740), had in their turn succumbed to their ancient rivals the Rashtrakutas, who succeeded to the bulk of their dominions, including Gujarat, where they had set up a branch line. For some two centuries (c.
