# Puelches, La Pampa

Puelches is a village and rural locality (municipality) lying on the National Route 152 in La Pampa Province in Argentina. It serves as the administrative center of the Curacó Department with its rural area expanding into the Lihuel Calel Department in the south of the province.
Though it was founded as a cattle town, in a traditional farming area, the main economic activities are salt production and mining. It is considered Argentina's geographical center by a national decree from 1978.

## Etymology

The town was referred to as Los Puelches by the media in the early 20th century. In 1941, the Governor of the province, Miguel Duval, proposed to rename it Coronel Bedoya to honor one of the officers who participated in the Conquest of the Desert. The proposal met criticism and it was decided to keep the original name which refers to the native Puelche people that inhabited the area before the arrival of the Argentine Army. The Mapudungun word can be translated as 'people from the east'.

## History

The area of Puelches has been populated by a series of natives for thousands of years, who were generally known as Puelche. The term did not refer to them as an ethnic group, but was rather a reference to the area they inhabited. In the 16th century, the Mapuche started their expansion into the area, assimilating the then-local hunting-gathering tribes, who called themselves gününa-këna, into their culture. The area was taken over and incorporated into the Argentine state, after the natives were defeated in the Conquest of the Desert in the 1870s by the national troops.
The village was founded in 1900 as an agricultural colony, named Los Puelches, by a national decree. Six years later, the local school, the magistrate's court and the civil registry were opened. In the early years of the 20th century Spanish and French settlers came into the region and integrated with the remaining locals and the creole population. Into the 1940s the region flourished as the growing flow of the Salado River enabled activities such as cattle farming, fishing and mining. It came to an end when the river flow was diverted by western provinces, causing a significant loss of surface waters in the whole province.
In 1978, Puelches was officially recognized as Argentina's geographical center by a national decree. A stone marker indicates the exact center. The developing committee was granted the municipality status in 1995.

## Geography

The village lies in south of La Pampa province, serving as the seat of the Curacó Department with its rural area expanding into the Lihuel Calel Department.
