Chandra or Chandar was a Hindu Brahmin ascetic who succeeded his brother, Chach of Alor, as king of Sindh region of the Indian subcontinent.
Chach ascended to the throne by marrying the king's widow, and appointed Chandar as his deputy.
Matta had formerly been the autonomous chief of Siwistan; however, he had been subjugated during one of Chach's campaigns, and intended to regain independence.
He sent an emissary to Siharas, ruler of Kannauj, noting that Chandar was a monk who allegedly spent his entire day at prayer, and who would thus be a weak foe.
During a parley with Sindhi forces, Siharas was seized; he agreed to end the war, sending hostages with robes of honor to Chandar.
