Nogai's daughter married a son of Kublai's niece, Kelmish, who was wife of a Qongirat general of the Golden Horde. Nogai was angry with Kelmish's family because her Buddhist son despised his Muslim daughter. For this reason, he demanded Toqta send Kelmish's husband to him. Nogai's independent actions related to Rus' princes and foreign merchants had already annoyed Toqta. Toqta thus refused and declared war on Nogai. Toqta was defeated in their first battle. Nogai's army turned their attention to Caffa and Soldaia, looting both cities.. Within two years, Toqta returned and killed Nogai in 1299 at the Kagamlik, near the Dnieper. Toqta had his son stationed troops in Saqchi and along the Danube as far as the Iron Gate. Nogai's son Chaka of Bulgaria, first escaped to the Alans, and then Bulgaria where he briefly ruled as emperor before he was murdered by Theodore Svetoslav on the orders of Toqta.
