According to Tiruvalangadu plates of Rajendra Chola, Madhurantaka Uttama's reign is placed after Aditya II.

Due to his young age, his rights to the Chola throne were probably set aside and Gandaraditya's younger brother Arinjaya was crowned king.

[4] Arinjaya ruled for a very short time – possibly for less than a year and on his death, his son Parantaka II (Sundara Chola) succeeded him.

[5] By the time Uttama was old enough to claim the crown, Sundara Chola had two sons – Aditha Karikalan (the one who took the head of the Vira Pandya) and Arulmozhi Varman.

[6][7] The Tiruvalangadu plates of Rajendra Chola I reveal that following Aditha Karikalan’s death, questions arose regarding succession.

Dated to the second regnal year of Rajaraja Chola, the Udaiyargudi inscription records that the government seized the lands of several people and their relatives, including Soman, Ravidasan (alias Panchavan Brahmadhirajan), Parameswaran (alias Irumudichola Brahmadhirajan), and Malaiyanur Revadasa Kramavittan, along with the property of Kramavittan’s son and mother.

[8][6][7] Despite Aditya II’s assassination in 971 CE, no action appears to have been taken by Uttama Chola during his reign to bring the perpetrators to justice.

It seems reasonable to conclude that if any credible evidence had existed against Uttama, Rajaraja’s son, Rajendra Chola, would not have adopted the coronation title of Madhurantaka II.

Under the guidance of his mother, Uttama played a significant role in codifying temple patterns, epigraphy, art, sculpture, and administrative record-keeping.

Other queens included Kaduvettigal Nandippottairaiyar, likely a Pallava princess, and Siddhavadavan Suttiyar, who was related to Vikramasola-Miladudaiyar, a prominent feudal king ruling over Miladu (part of present-day South Arcot District).

At other places like the Choleeswara temple at Kurralam which was sung by Appar and Sundarar, there is an inscription that says it was built by Sembiyan Mahadevi[2] She survived this king and lived on for another 16 years into the reign of Rajaraja I.

[17] Two sculptures of Uttama (Madhuranthaka Devar) and his mother can be found in the Southern wall of the inner Prakara of the Konnerirajapuram (aka Thirunallam) temple near Kumbakonam.
