Nimaj is an ancient town under the Pratihar rulers of Mandore.
The Gurjar Pratihar rulers built numerous temples in Nimaj during the 9th century. Magarmandi Mata temple is one of them.
Rao Uda Ji, grandson of Rao Jodha Ji (founder of Jodhpur) became a Sovereign ruler of Nimaj and Jaitaran, and founded the sub clan popularly known as Udawat Rathores. Thakur Jagram Singh was the first Thikanedar of Nimaj from 1708. Nimaj was later amalgamated with Jodhpur. Thakur Surtan Singh fought and died in battlefield in 1820 AD against Ali Gol and Marwar Army. The present Thakur is the 23rd generation of descent from Rao Jodha Ji. The Thakurs of Nimaj were one of the eight "Sirayats" (highest honour given to feudal lords for their bravery and they formed the permanent advisory senate of privileged Thakurs) of Marwar. Once Sher Shah Suri told that "for a handful of Bajra I would have lost the sultanate (Kingdom) of Delhi" after the fighting with Udawat - Rathores at the battlefield of "Giri Sumel". In the history, Dingal Poetry, Shubraj and folklores a lot about bravery, sacrifice, courage and chivalry of the Thakurs of Nimaj is there. They are also called as "Marwar ra Bhad Kiwad", Meaning the fortress gates of Marwar in the honur. 
Now Nimaj Palace is opened for tourism as a hotel. Nearby, Chhatrasagar is also a good tourist place, which is made by Thakur Chhatra Singh in the nineteenth century.
