The Orang National Park has historically been home to a variety of mixed settlement patterns. Up until 1900, members of the local ethnic community lived in the park. The indigenous population left the area because of an epidemic sickness. But in 1919, the British government designated the entire region as the Orang Game Reserve. As a result, the Game Reserve is directly under the State Government Forest Department’s management in order to satisfy all Project Tiger requirements for the National Parks. Later in 1985, the Park officially became a recognised wildlife sanctuary. But after being renamed Rajiv Gandhi Wildlife Sanctuary in 1992, it was later changed back due to popular outcry. The sanctuary finally received full National Park status in the year 1999.
