The largest settlement within Zonda is concentrated towards the northeast of the department in the village of Villa Basilio Nievas, which is also known simply as "Zonda". Much of the west of the department has a mountainous, rugged terrain that is sparsely populated.
The name of the department comes from indigenous[which?] roots, meaning "high sky". Its name refers to the warm wind characteristic of the province. Zonda has a hilly landscape with sparse vegetation and its economy centers around wine and fruit cultivation, as well as tourism.
History
Settlement of the region dates back to the Ullum-Zonda, a community of the Huarpe people of the first millennium. Their presence in the region was characterized by agricultural practices and the production of ceramics. When the Spanish arrived in the region in the 16th century, following the establishment of San Juan de la Frontera, they did not immediately settle in Zonda. As time progressed and the empire expanded, the Huarpe people of the area began to disappear.[further explanation needed]
The late 17th and 18th centuries saw the beginning of Spanish agricultural conversion of the region, when land owners such as Matias Sanchez de Loria and Cornelius Albarracín (maternal grandfather of Domingo Faustino Sarmiento) began using the land to cultivate grapes and olives.
Because the region has been sparsely populated compared to other regions within Argentina, it was initially part of a larger department within San Juan Province which contained the settlements of Marquesado (in present-day Rivadavida) and Villa Ibáñez. Marquesado had been founded in the late 19th century by the Echezarreta brothers, and it popularized the Quebranda de Zonda, a ravine on the district's eastern border, as a summer resort within the province. Zonda did not become an independent department until the 20th century, when a 1935 act separated it from Rivadavida. Its official borders were not defined until 1942, when the organic municipal act of September 4 was enacted. The department's largest settlement, Villa Basilio Nievas, was established as the government seat of Zonda.
