The Chahamanas of Ranastambhapura were a 13th century Indian dynasty. They ruled the area around their capital Ranastambhapura (Ranthambore) in present-day Rajasthan, initially as vassals of the Delhi Sultanate, and later as sovereigns. They belonged to the Chahamana (Chauhan) clan of the Rajputs, and are also known as Chauhans of Ranthambore in vernacular Rajasthani bardic literature.
The Chahamana dynasty of Ranastambhapura was established by Govinda-raja, a member of the Shakambhari Chahamana family (also known as the Chauhans of Ajmer). Govinda was the son of Prithviraja III, who was defeated and killed in a battle with the Ghurids, in 1192 CE. The Delhi Sultan Muhammad of Ghor appointed Govinda as his vassal at Ajmer. However, Prithviraja's brother Hari-raja de-throned him, and himself became the ruler of Ajmer. Govinda then established a new kingdom with its capital at Ranastambhapura (modern Ranthambor). After the Muslim conquest of Ajmer, he granted asylum to Hari.
Balhana, the son of Govindaraja, is recorded as a vassal of the Delhi Sultan Iltumish in 1215 CE, but declared independence in the later years. Balhana's elder son Prahlada succeeded him, and died in a lion-hunt. Prahlada's son Viranarayana was invited to Delhi by Iltumish, but was poisoned to death there. Iltumish captured the fort in 1226 CE. Balhana's younger son Vagabhata then ascended the throne. He recaptured Ranthambore during the reign of the Delhi ruler Razia (r. 1236-1240). He successfully defended the fort against the Delhi Sultanate's invasions in 1248 and 1253 CE.
Vagbhata's son Jaitrasimha achieved military successes against Paramaras of Malwa and other Rajput chiefs. He, however, lost his sovereignty to Nasir-ud-din, and ended up paying tribute to the Delhi Sultanate.
Hammira-Deva, the last ruler of the dynasty, was also its most powerful ruler. He ascended the throne sometime between 1283 and 1289 CE. Hammira Mahakavya, his biography by Nayachandra, is one of the few non-Muslim sources for the region's history from that period, and enables the historians to verify the accounts of the Muslim chronicles. The Balvan inscription of 1288 CE mentions that Hammira captured the elephant force of Arjuna II, the Paramara king of Malwa. The Hammira-Mahakavya suggests that he also defeated Arjuna's successor Bhoja II. He also subjugated the Paramara branch of Abu. He is said to have marched to Chitrakuta (Chittor). He raided several neighbouring Rajput territories, including Medapata (Mewar) and Vardhamanpura (modern Wadhwan). Hammira's wars with fellow Hindu Rajputs ultimately left him without any allies against the Delhi Sultanate. He successfully resisted invasions by Jalal-ud-din and Ala-ud-din's general Ulugh Khan. But he was killed in an invasion led by Ala-ud-din Khilji in 1301.
