Mahadeva, who ruled approximately 1261–1270 CE, was a king of the Seuna (Yadava) dynasty in the Deccan region of India.

His reign saw Mahadeva defeating the Shilaharas of Kolhapur and crushing a rebellion by the Kadamba rulers, who were under his authority.

He initiated campaigns against other kingdoms, waged an inconclusive war against the Kakatiya queen Rudrama, and was defeated by the Hoysala king Narasimha II.

At the time of his death, it is likely that his son Ramachandra was either not yet born or still too young to be crowned yuvaraja (heir apparent) or to ascend the throne.

[3][4][5] Many powerful officials and generals who had sworn allegiance to Mahadeva, including Hemadri and Tikkama, sided with Ramachandra.

[1] A third Mahanubhava text, Bhanuvijaya, has a highly exaggerated version of the event, claiming Ammana was executed,[5] but this account is considered unreliable.

[1] After usurping the throne from his cousin Ammana with a coup in the capital Devagiri, Ramachandra increased the Senua dynasty by precipitating wars with neighboring states including the Paramaras, Vaghelas, Hoysalas, and the Kakatiyas.

[1][2] By 1296 CE, following an invasion from a Muslim army from the Delhi Sultanate led by Alauddin Khalji, the Yadavas had to pay an annual tribute.

[3] But after around 1303–1304 CE, when Ramachandra ceased to pay the tribute, Alauddin sent his general Malik Kafur and launched an invasion in 1308.
