Juan de Ayolas

Juan de Ayolas was the leader of a 1537 Spanish expedition up the Paraná River, sent in the search for a route to the Incas. His encounter with the Guaraní led to the founding of Asunción and offered the Spanish a settlement model very different from their failed first stay at Buenos Aires: one in which they took control of existing labor and tribute systems rather than relying on coerced labor that local people resisted.## Expedition and Encounter The Spanish had begun settling Buenos Aires in 1534, but the settlement struggled to survive. The Charrúas and Querandí refused to supply food or work for the newcomers, and the area offered no local silver or gold. Spanish expeditions consequently set out to find richer territory and populations they believed they could compel to work.

In 1537, Ayolas led one of those expeditions upriver along the Paraná, searching for a route to the Inca state. The expedition encountered the Guaraní, a sedentary agricultural people whose crops included maize and cassava. After a brief conflict, the Spanish overcame Guaraní resistance. The contrast with Buenos Aires was consequential: the expedition had found a population and an established society whose existing structures could be appropriated for colonial rule.## Asunción and Colonial Rule The Spanish founded Nuestra Señora de Santa María de la Asunción, the town that remains Paraguay’s capital. The conquistadors married Guaraní princesses and established themselves as a new aristocracy. Rather than build their colony around independent Spanish farming, they adapted the Guaraní systems of forced labor and tribute, placing themselves at the top of those arrangements.

Within four years, Buenos Aires was abandoned as the Spaniards who had settled there moved to the new town. Buenos Aires would not be resettled until 1580. The movement from the failed settlement to Asunción thus records a change in colonial strategy: the Spanish sought not simply favorable land, but a population and labor system they could dominate.## Historical Significance Ayolas’s expedition forms part of the book’s account of the logic of European colonization in the Americas. The Spaniards’ initial difficulty at Buenos Aires exposed the limits of a settlement where local people could not be made to provide labor and where the hoped-for precious metals were absent. At Asunción, by contrast, the colonists appropriated existing systems of labor and tribute and made themselves the ruling elite.

The episode also anticipates the book’s broader account of extractive institutions. Political power allows a narrow group to organize economic life for its own benefit; the resulting wealth, in turn, can help that group maintain its power. The description of the Guaraní settlement does not establish every later development of that institutional pattern, but it presents its colonial foundation in concrete form: a new aristocracy at the helm of labor and tribute.
