Jagadeva, also known as Jagaddeva or Jagdev Parmar, was an 11th-12th century prince from the Paramara dynasty of central India. He is known from an inscription discovered at Jainad and some folk legends. His political status is uncertain, although according to one theory, he may have been a vassal of the Western Chalukyas.
The coins and inscriptions from Jagadeva's period have been found in the northern parts Berar and Deccan regions, not the traditional Paramara territory of Malwa. These regions were dominated by the Chalukyas of Kalyani. An inscription discovered at Jainad names Jagaddeva as the son of the Paramara king Udayaditya (reigned c. 1060–1086). Four gold coins bearing the name "Shri-Jagadeva" have also been discovered. Several scholars, including P. C. Roy, identify the issuer of these coins as the Paramara prince. M. H. Krishna surmised that the Chalukya king Someshvara was known by the title "Jagaddeva" ("Lord of the world") in the northern part of his kingdom, and it was he who issued these coins. However, all the known Chalukya coins feature Kannada script, while coins of Jagaddeva feature the Nagari script used by the Paramaras. Therefore, Krishna's theory is purely conjectural.
V. P. Rode theorizes that Jagadeva accepted the suzerainty of Vikramaditya VI of Kalyani. Vikramaditya made him governor of Berar and a part of Deccan. P. C. Roy disagrees with this theory, arguing that a vassal could not have issued gold coins in his own name, and the coins do not mention the Chalukyas.
A legendary account in the Ras-Mala states that Jagadeva succeeded Udayaditya as the king. Therefore, D. C. Ganguly suggested that Jagadeva was another name for Lakshmadeva (r. c. 1086-1094 CE). According to Ganguly's theory, he abdicated the throne in favour of his brother Naravarman (r. c. 1094-1133 CE). He then governed the southern part of the Paramara kingdom (northern parts of Berar and Deccan) until at least 1112 CE. Later, he lived at the Chalukya court at Vikramaditya's invitation. K. C. Jain disagrees with this theory, arguing that Jagaddeva and Lakshmadeva were two distinct princes.
