In the early 19th century, the araucanization of the natives of northern Patagonia intensified, and many Mapuches migrated to Patagonia to live as nomads that raised cattle or pillaged the Argentine countryside. The cattle stolen in the incursions (malones) were later taken to Chile through the mountain passes and traded for goods, especially alcoholic beverages. The main trail for this trade was called Camino de los chilenos and runs a length around 1000 km from the Buenos Aires Province to the mountain passes of Neuquén Province.
