Udayaditya Sindhuraja (IAST: Sindhurāja) was an Indian king from the Paramara dynasty, who ruled the Kingdom of Malwa in the late 10th century.
According to the 14th century poet Merutunga's Prabandha-Chintamani, Sindhuraja was the biological son of Simhadantabhatta (Siyaka), while Munja was an adopted child.
[1] Tilaka-Manjari, a work composed by the Paramara court poet Dhanapala eulogizes Sindhuraja as a great hero and "a lion for the line of rutting elephants of Indra".
This suggests that he recovered the territories on the Paramara kingdom's southern frontier, that his predecessor Munja had lost to the Kalyani Chalukya king Tailapa II.
[4] The Nava-sahasanka-charita narrates a partly-mythological story about Sindhuraja defeating the demon king Vajrankusha to win over the Naga princess Shashiprabha; in this campaign he is supported by the vidyadhara leader Shashikhanda.
According to the inscription, when Sindhuraja saw Chamundaraja's army from a distance, he fled with his elephant forces, and lost his well-established fame.
[15][13] The 1092 CE Sasbahu Temple inscription of the Kachchhapaghata ruler Mahipala states that his ancestor Kirtiraja defeated the prince of Malava, whose soldiers fled the battlefield, leaving behind their spears.
