In 1922 AD, the Koya tribal community revolted at Rampa against the British under leadership of Alluri Sree Rama Raju. They  revolted against the British Forest laws and the exploitation of the tribes by the tribal chiefs called Muthandars. But, the revolt  was suppressed when Alluri Sree Rama Raju was assassinated at Mampa village, Visakhapatnam on May 7, 1924.
