Raghuvaṃśa
Raghuvamsha (Sanskrit: रघुवंश, Raghuvaṃśa) is a Sanskrit mahakavya (epic poem) by the most celebrated Sanskrit poet Kalidasa. Though an exact date of composition is unknown, the poet is presumed to have flourished in the 5th Century CE. It narrates, in 19 sargas (cantos), the stories related to the Raghu dynasty, namely the family of Dilipa and his descendants up to Agnivarna, who include Raghu, Dasharatha and Rama. The earliest surviving commentary written on the work is that of the 10th-century Kashmirian scholar Vallabhadeva.
The most popular and widely available commentary, however, is the Sanjivani, written by Mallinatha (ca.1350-1450).
Geographical and historical references
The warrior Raghu leads a military expedition to Transoxiana. He defeats and subjugates local people 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."
