Somavamshi dynasty: Somavamshi King Janamajaya-I Mahabhavagupta (c. 882–922 CE) consolidated the eastern part of his kingdom comprising the modern undivided Sambalpur and Bolangir districts and established a matrimonial relationship with the Bhauma-Kara dynasty ruling over modern coastal Odisha. After Uddyotakeshari (c. 1040–1065 CE), the Somavamshi kingdom declined gradually. After the decline of the Somavamshis the area came under the Telugu Chodas for a short period. The last Telugu Choda king of south Kosala was Somesvara III, who was defeated by Kalachuri king Jajalladeva-I around 1110 CE.
Kalachuri Dynasty: Jajalla-deva, a ruler of the Kalachuri dynasty of Ratanpur (the historical capital of Chhattisgarh), defeated the ruler of Sonpur and annexed it to his kingdom in 1110. The region was administered under the Kalachuri rulers of Ratanpur from 1110 to 1238.[1]
Eastern Ganga Dynasty: The last ruler of the Kalachuri Dynasty, Pratapmalla, invaded the frontiers of the Ganga territory along with his son Paramardi Dev. Anangabhima Deva III, the Eastern Ganga ruler, sent a large force under the command of his able Brahman commander, Vishnu. The two forces met face to face at the Seori Narayana village in undivided Sambalpur district on the banks of the river called Bhima near the Vindhya hills and the Kalchuris were defeated for the first time by the Gangas. The Chateswara Temple Inscription of Anangabhima mentions that Vishnu terrorized the Kalachuri king so much that the latter "perceived Vishnu every where throughout his kingdom."[7] Pratapmalla was taken prisoner and forced to cede the Sambalpur-Sonepur-Bolangir tracts along with parts of what is now Chhattishgarh state to the Ganga kingdom. Later, with the advice of his minister Vishnu, Anangabhima established a diplomatic and matrimonial alliance with the Kalachuris by offering the hand of his daughter Chandrika in marriage to the Kalachuri prince, Paramardi Dev. Once the alliance was secured, the Ganga forces multiplied in strength. Paramardi Dev died in the final recorded battle of Narasingha Deva I's invasion of Bengal at Umurdan (present-day Amarda in Mayurbhanj district).
Gajapati Empire: After the Eastern Ganga dynasty, Western Odisha was ruled by the mighty Gajapati Empire. Under Kapilendra Deva, the Gajapatis built an empire stretching from the lower Ganga in the north to the Kaveri in the south. But continued aggression of the Bengal sultanate from the north and Vijayanagara and Bahmani empires from the south weakened the Gajapati empire. Ultimately, Ramai Deva, a Chauhan Rajput from North India, founded Chauhan rule in western Orissa. According to the details placed in all the contemporary literary accounts, Ramai Deva was born to one of the queens of Hutumbur Sing, alias Hambir Dev. His pregnant queen, Jayanti Devi, fled Garh Sambhar with some of her followers when Vishala Dev was killed by a Muslim king in a battle, who has been identified with Firuz Shah Tughlaq. Jayanti Devi found refuge in the house of a Brahmin ruler of Kholangarh division of the Patna state known as Chakradhar Panigrahi. Ramai Deva possibly murdered or killed the rulers and became ruler of this region.

Western Odisha is culturally influenced by several different cults and religions. Its history dates back to the Mahabharat and Buddhist period. Folk songs and dances of this area have been revived and recognized during the last quarter century, including Danda (Danda Yatra and Danda Nata), which is considered to be one of the oldest forms of variety entertainment in India, as well as the modern "Krushnaguru Bhajan", a type of folk lyrics and songs. Sambalpuri songs are quite popular throughout Odisha. Some hits include Rangabati, Ekda Ekda, Dalkhai, and Panbala Babu.[5][6]
Rangabati is a modern Sambalpuri song inspired by folk music, written in 1975, which enjoyed international popularity in the 1970s and 1980s. It was sung by Jitendra Haripal and Krishna Patel.
