Mir Qasim, who continued to provide military support to him in his battles against the
Mughal Emperor from
Monghyr to
Buxar in Bihar; he opposed the Dewani powers that the British had gained over Bengal, Bihar, and Orissa as a result of the
Treaty of Allahabad in 1765. In 1772, he marched into Huseypur and killed Govind Ram who was appointed as the revenue farmer for the East India Company.

Chait Singh of
Benares state in 1781 he renewed his campaign against the Britishers or in other words the
East India Company. He later established
Tamkuhi Raj approximately 109 kilometers from Husseypur, northeast of modern-day
Kushinagar within the Kingdom of
Oudh, seeing the growing influence and power of the
East India Company. Maharaja Fateh Shahi changed his tactics and around 1789, he ceased his rebellious ways and handed the administration of the state to his sons . ==Legacy==
