In 1838 A.D., English rulers separated Jhalawar state from Kota state and gave it to Jhala Madan Singh, the grandson of Jhala Zalim Singh. He developed his administration services to develop the state of Jhalawar. He resided in Jhalara Patan for a long time and started to build the Garh Palace (1840 - 1845 A.D). He was the first ruler of Jhalawar state and made a significant contribution in the history of Jhalawar. Jhala Madan Singh ruled Jhalawar from 1838 to 1845. After his death, Jhala Prithvi Singh became the ruler of Jhalawar and ruled for around 30 years.
