The province is home to four indigenous groups: The Tehuelches, the Puelches, the Pehuenches, and the Mapuches. Almost all of the indigenous population in the province are the Mapuches with the rest being small in number where their few descendants live in the neighbouring provinces. The Mapuches along with some of the Pehuenches originally lived in the western parts of the province although today, they mainly live in the southern parts of the province. The Tehuelches were nomadic people that hunted on the steppes in the province. The Puelches, being also nomadic, lived on the northern margins of Nahuel Huapi Lake and the surrounding forests in the Andean mountains, living off hunting and fishing. It is estimated that Mapuches started coming to the region before 1880 from Chile, leading to the imposition of their culture onto the other indigenous groups. Originally agricultural people, the Mapuches became nomadic upon arrival to the province due to the utilization of horses.
