Jayachandra

Jaya-chandra (IAST: Jayacandra, r. c. 1170–1194 CE) was a king from the Gahadavala dynasty of northern India. He is also known as Jayachchandra (IAST: Jayaccandra) in inscriptions, and Jaichand in vernacular legends. He ruled the Antarvedi country in the Gangetic plains, including the important cities of Kannauj and Varanasi. His territory included much of the present-day eastern Uttar Pradesh and some parts of western Bihar. The last powerful king of his dynasty, he was defeated and killed in 1194 CE, in a battle near Yamuna against a Ghurid army led by Muhammad of Ghor.

A fictional account of Jayachandra (as Jaichand) occurs in a legendary text ''Prithviraj Raso''. The epic poem was likely written centuries after his death. According to this account, he was a rival of another Indian king, Prithviraj Chauhan. His daughter Samyukta eloped with Prithviraj against his wishes, and he allied with the foreign non-Hindu Ghurids to ensure Prithviraj's downfall. The name "Jaichand" became synonymous with the word "traitor" in folklore of northern India because of this legend. Provided by Wikipedia
