Prithvivarman was succeeded by his son Madanvarman. Many incidents of his reign can be known from contemporary inscriptions and coins. He ruled for a period of 34 years. He had conquered the Chedi king, Kashi king, Malava king and some other kings.
Conquest over Chedi dynasty: Madanvarman conquered the II king Gayakarna and established his authority over his kingdom. 48 silver coins of Madanvarman have been found in villages Pawar of Rewa state.
War with Gahadvala king: Madanvarman reconquered Chattarpur from Govindachandra in 1147 A.D. However, it is learnt from the drama, `Rambhamanjari` that Govinda chandra`s son vijaya chandra had defeated Madanvarman. It indicates that Chandel king might have been successful in the beginning but in the end Gahadvala king defeated Madanvarman.
War of Malava: It is learnt from the drama of `Rambhamanjari` that king Govinda had conquered Malava from Yasovarman of Parmara dynasty. But in the way of eastern Malava lied the kingdom of the Chandellas. So either the Chandellas gave way to Govinda Chandra or he moved further after defeating the Chandellas.
Augasi inscription indicates that in 1134 Madanvarman had written a grant in Bhilasa. This indicates that he had conquered Bhilasa from Yasovarman. According to Dr. Chakarvarti, Yasovarman`s son Lakshamanvarman ruled over Bhilasa. This shows that Lakshmivarman had again conquered Bhilasa from Madanvarman.
War with the Chalukyas: According to `Kumarapala Charit Siddharaj` the king of Gujrat had defeated king Madanpala of Mahoba and then attacked Kalanjar. Chandrabardai has mentioned the defeat of the Chalukya king. Kalinjar inscription also indicates that Madanvarman had defeated the Chalukya king.
Extent of the empire: According to historians the empire of Madanvarman extended to Rewa in the east Betava in southwest, Yamuna in the north and river Narmada in the south.
