Princely State of Sarwan was amongst the former native states during the rule of the British Empire in India. During the early 19th century, the region was appointed as one of the princely states of India under the indirect rule of the British administration. The region was scattered over a total area of 71 sq km and is a part of the Indian state of Gujarat. The region comprised of a total population of 5,545 in the year 1921. The erstwhile princely state of Sarwan was under the administrative control of the Central India Agency, which was a political office of the British Government of India that spanned over the northern half of current Indian state of Madhya Pradesh. The princely state of Sarwan was located around 15 miles towards the north northwest of the town of Ratlam.
The Rathor Rajputs were the ruling family of Sarwan state. In the year 1728, the jagir was granted to the grand nephew of the founder of Ratlam state. This was done as a reward for providing a service. The state of Sarwan consisted of 14 villages and 2 villages of them were seized from the native ruler or the Thakor of Sonkhera in Gwalior; one village from the princely state of Panth Piploda; 6 villages from the princely state of Ratlam; one village from the princely state of from Sailana; 3 villages from the princely state of from Piploda; and one village from the princely state of Dewas Junior. Only the first 3 villages were guaranteed, and the rest, including the village of Sarwan, were not guaranteed. The native ruler of the princely state of Sarwan held the title of Thakor and possessed the Jagir of Sakatkheri in Panth Piploda from the jagirdar of Mandawal on an annual tribute. In the year 1909, the claims of the princely state of Ratlam, Piploda and Jaora and the Amargarh village were discarded by the British Government of India. The region was held by Sarwan under the suzerainty of Ratlam.
The last ruler of the princely state, who was the 11th of his line, acceded his state to the newly formed Union of India, also known as Dominion of India after the partition of India on 15th August 1947.
