The oldest settlement in Sawai Madhopur was around the Ranthambhore fort. The exact origin of the Ranthambhore fort is still disputed but it is generally accepted that there was a settlement at the site of the Fort, as far back as the 8th century AD. It is widely believed that the construction of the Ranthambhore fort was started during the reign of the Chauhan rajput king Sapaldaksha in 944 A.D. Another theory stipulates that King Jayant, also a Chauhan rajput, built the Ranthambhore fort during 1110 AD. It is most likely that the construction of the fort commenced during the mid 10th Century AD and continued for a few centuries after that.

Since, the Ranthambhore Fort controlled the trade routes between North India and Central India: it was highly coveted by the rulers of North India. The Ranthambhore Fort has its golden moments during the reign of the king Rao Hammir, the last ruler of the Chuhan dynasty 1282-1301 AD). During 1300 AD, Ala-uddin khilji, the ruler of Delhi sent his army to capture the fort. After three unsuccessful attempts, his army finally conquered the Ranthmbhore Fort in 13th century and ended the reign of the chauhanas. In the nest three centuries the Ranthambhore Fort changed hands a number of times, till Akbar, the great Mughal emperor, finally took over the Fort and dissolved the State of Ranthambhore in 1558. The fort stayed in the possession of the Mughal rulers till the mid 18th century.

During the mid 18th century, the Maratha rulers of western India were gradually increasing their influence in this region. In order to check the growing influence of the Marathas, Sawai Madho Singh, the ruler of Jaipur state, unsuccessfully, requested the Mughal emperor to hand over the Ranthambhore fort to him, in 1763, Sawai MadhoSingh fortified the nearby village of Sherpur and renamed it Sawai Madhopur. This town, which is now commonly known as the " "Sawai Madhopur city" lies in a narrow valley between two parallel hills, at the south western edge of the Ranthambhore National Park. Two years later, the Mughals handed over the fort to the Jaipur state.
