The history of Arusha National Park is deeply rooted in the presence of the
Rwa people, the first inhabitants of the region. Their legacy predates significant
colonial exploration and control in the area. In 1876, Hungarian explorer
Count Teleki visited the
Momella area, one of the park's key attractions in the region. Following his visit, he remarked on the abundance of hippopotamuses and black rhinos he observed. In 1907, the Trappe family from England settled in the park during the occupation of the
British's
Tanganyika Territory, primarily for farming in Momella, and utilized large portions of the area as a cattle ranch. Mrs. Trappe, the first female professional hunter in East Africa, generously donated a significant portion of the Momella estate to establish a game reserve. This farm was incorporated into the park when it was founded in 1960. Initially, the park was established as
Ngurdoto Crater National Park, encompassing only a small section of what would become Arusha National Park, primarily to protect areas like the Ngurdoto Crater. At that time, Mount Meru was not included in the park's boundaries. In 1967, the park's name was changed to Arusha National Park after the Mount Meru area was added. The name "Arusha" is derived from the
Waarusha people who inhabited the western portion of the region. Following Tanzania's independence, the park was officially established, and the entire Mount Meru was integrated into its boundaries. ==Ecology==
