Himatnagar was founded in by Ahmad shah of Gujarat Sultanate and named it Ahmednagar after himself. He founded the town to keep Raos of Idar State in check.
In 1658, Aurangzeb became emperor and reintroduced jizya. Through his ferman of 1665 he prohibited Jains and Hindus from closing their shops on ‘Pachusan’ (paryushan), last day of the month and eleventh day; ordered that arrangements be made to ensure that Kolis of Himmatnagar do not disturb Muslims when they recite their Friday prayers.
When the Marwar dynasty took Idar in 1728, Ahmednagar soon fell into their hands. After the death of Maharaja Shivsing, in 1792, his brother Sangramsing took Ahmednagar and the country around; and, in spite of the efforts of his nephew Gambhirsing, became an independent chief. Sangramsing was succeeded by his son Karansing. The later died in 1835, and Erskine, the British Agent, who was in the neighbourhood with a force, moved to Ahmednagar to prevent the queens from becoming satis. The sons of the deceased Maharaja begged Erskine not to interfere with their customs. Finding him resolved to prevent the sati practice, while pretending to negotiate, they secretly summoned the Bhils and other turbulent tribes, and in the night, opening a way through the fort wall to the river bed, the queens burnt themselves with their deceased husband. The sons of the deceased Maharaja fled, but subsequently gave themselves up, and, after entering into an engagement with the British Government, Takhtsing was allowed to succeed his father as Maharaja of Ahmednagar. Some years later he was chosen to fill the vacant throne of Jodhpur State. He tried to keep Ahmednagar and its dependencies, but, after a long discussion, it was, in 1848, ruled that Ahmednagar should revert to Idar State.
