Ramanuj Pratap Singh Deo

Ramanuj Pratap Singh Deo (1901-1958) was the last ruler of erstwhile Korea State. He was crowned as the king of Korea in 1925 and continued to rule the state until the state's merger with independent India on 1 January 1948. He was a Rajput by caste. He had represented the ruling Chief in the second Round Table Conference held in London in 1931.

He is notorious for killing the last three surviving Asiatic cheetahs of India. It is believed that he killed as many as 1,710 tigers in the central part of India. His granddaughter, Ambica Singh, defended her grandfather claiming that he never killed big cats for fun but rather hunted only those animals who had turned man-eaters. Nevertheless, while tigers are well-known for occasionally becoming man-eaters, there is no documentation of wild cheetahs ever killing a human, and the number of tigers reported to have become man-eaters in his lifetime is far less than the as many as 1,710 tigers he reportedly killed.

He died in 1958.
