Definition of Raghuvamsha

Kalidasa's Raghuvamsha tells of the family of Rama and his descendants, including the conqueror Raghu. The warrior Raghu leads a military expedition to Transoxiana. He defeats and subjugates local peoples along the way (presumably on his march through Central Asia) until he reaches the Vankshu, as the ancient Indians called the Oxus River. There, Raghu's army battles the Hepthalites, or White Huns, whom the Indians called Hunas and Mlecchas (barbarians). The Hepthalites are defeated, and the Raghuvamsha boasts of "The exploits of Raghu, whose valor expressed itself amongst the husbands of the Huna women, became manifest in the scarlet color of their cheeks."
