In the rule of his son Maharaja Achal Singh, they fought with Aurangzeb and lost that war , then they moved to Palamu area and established Namudag -Mahuari Raj (detailed information in the upcoming paragraph).

 * The Ranka Line : The younger son, Prince Puran Mal, set his sights on Palamu. Under the guidance of his father, Dev Shah, Puran Mal served as the General of the army that assisted the Chero King, Bhagwat Rai, in conquering Palamu. In gratitude for his valor, the Chero King appointed Puran Mal as his Dewan and granted him the estates of Ranka and Chainpur. Though they began as allies, the Ranka branch later fought the Cheros to secure their own independent territory. In British Era they got title of Princely state. Raja bahadur of Ranka raj also participated in the world war 2 with the British and got much respect.
