Gangeyadeva (IAST:, r. c. 1015-1041 CE) was a ruler of the Kalachuri dynasty of Tripuri in central India. His kingdom was centered around the Chedi or Dahala region in present-day Madhya Pradesh. During the early part of his reign, Gangeyadeva seems to have ruled as a vassal, possibly that of the Paramara king Bhoja. He fought against the Chalukyas of Kalyani in an alliance with Bhoja, but was forced to retreat after some initial successes. In the 1030s, he raided several neighbouring kingdoms and established himself as a sovereign ruler. He appears to have annexed Varanasi to Kalachuri dominions. As a feudatory Gangeyadeva succeeded his father Kokalla II on the throne of Tripuri around 1015 CE. In his 1019 CE Mukundpur inscription, Gangeyadeva assumes the modest titles Maharha-Maha-Mahattaka and Maharaja. This title is not as high as the imperial title Maharajadhiraja, which suggests that Gangeyadeva was a feudatory to another king, possibly the Paramara king Bhoja. Chalukyas of Kalyani Gangeyadeva fought a war against the Chalukyas of Kalyani, possibly as a vassal of Bhoja. The triple alliance of Bhoja, Gangeyadeva and Rajendra Chola engaged the Chalukya king Jayasimha II at multiple frontiers. The Kalachuri inscriptions boast that the king of Kuntala (that is, Jayasimha) abandoned his spear while wanting to run away from Gangeyadeva. The Chalukya inscriptions also claim success against their enemies. Thus, it appears that Gangeyadeva and his allies achieved some military successes in the beginning, but were ultimately forced to retreat. Paramaras The Kalvan inscription, the Udaipur Prashasti inscription and Merutunga's Prabandha-Chintamani state that Bhoja defeated the ruler of Chedi. Parijata-Manjari (c. 1213 CE) by Bala Saraswati Madana, specifically identifies the defeated ruler as Gangeya. A verse engraved on a stone slab in Bhoj Shala also suggests that Bhoja defeated Gangeyadeva of Tripuri. The 1223 CE Dhar inscription of the Bhoja's descendant Arjunavarman also mentions Bhoja's victory over Gangeya. It is not certain whether Bhoja defeated Gangeyadeva before or after their joint war against the Chalukyas of Kalyani. According to one theory, Bhoja defeated Gangeyadeva before his Chalukya campaign, in which Gangeyadeva must have fought as a Paramara vassal. V. V. Mirashi believed that Bhoja may have subjugated Gangeyadeva before 1019 CE, when Gangeyadeva issued his Mukundpur inscription. A contradictory theory is that the two turned enemies after their campaign against the Chalukyas. Based on an inscription found at Mahoba, K. M. Munshi theorized that the two
