292 THE GUPTA EMPIRE AND THE WHITE HUNS destroyed or absorbed into the surrounding popula- tion. The extinction of the Ephthalite power on the Oxus necessarily dried up the stream of Hun immigration into India, which enjoyed immunity from foreign attack for nearly five centuries after the defeat of Mihiragula. The following chapters will tell how India made use, or failed to make use, of the opportunity thus afforded for internal development unchecked- by foreign aggres- sion. Very little is known about the history of India during the second half of the sixth century. It is cer- tain that no paramount power existed, and that all the states of the Ganges plain had suffered severely from the ravages of the Huns, but, excepting bare catalogues of names in certain local dynastic lists, no facts of general interest have been recorded. The king called Siladitya of Mo-la-po by the Chinese traveller, Hiuen Tsang, has no political connection with Harsha-Sila- ditya of Kanauj and Thanesar, as has been commonly supposed, or with the history of Northern India.
