The Wayuu had never been subjugated by the Spanish. The two groups were in a more or less permanent state of war. There had been rebellions in 1701 , 1727 , 1741, 1757, 1761 and 1768. In 1718, Governor Soto de Herrera called them "barbarians, horse thieves, worthy of death, without God, without law and without a king". Of all the Indians in the territory of Colombia, the Wayuu were unique in having learned the use of firearms and horses.
